Classification and Advantages of Plug Valves(2024年01月30日)

tznt — 2024-01-30T10:48:18+0900

https://www.wsv-valve.com/classification-and-advantages-of-plug-valves.html

Classification and Plug Valve Advantages
Ⅰ. Introduction of plug valves

Plug valve is a quick opening and closing through the valve. Because the movement between the rotary sealing surfaces has the function of wiping, it can completely prevent contact with the flowing medium when fully opened, so it can also be used for the medium with suspended particles. Another important feature is that it is easy to adapt to multi-channel structure, so that one valve can obtain two, three or even four different flow channels. This can simplify the design of the piping system, reduce the consumption of valves and some connecting accessories required in the equipment.

Ⅱ. Classification of plug valves

According to the structural form, it can be divided into four types including tight plug valve, self-sealing plug valve, plug valve and oil filling plug valve. According to the channel form, it can be divided into straight plug valve, three-way plug valve and four-way plug valve. There are also ferrule plug valves. Plug valves are classified by purpose including soft sealing plug valve, oil lubricated hard seal plug valve, lifting plug valve, three-way and four-way plug valve.

1. Soft seal plug valves

Soft seal plug valves are often used in harsh environments such as corrosive, highly toxic and high hazard media, where leakage is strictly prohibited, and where valve materials will not pollute the media. According to the working medium, the valve body can be made of carbon steel, alloy steel and stainless steel.

2. Oil lubricated hard seal plug valves

Oil lubricated hard seal plug valves can be divided into conventional oil lubricated plug valves and pressure balanced plug valves. Special grease is injected from the top of the plug body between the conical hole of the valve body and the plug body, then an oil film is formed to reduce the opening and closing torque of the valve, to improve sealing performance and service life. The working pressure can reach 64mpa, the maximum working temperature can reach 325 degrees, and the maximum diameter can reach 600mm.

3. Lifting plug valves

There are many structural forms of lifting plug valve material. According to the materials of sealing surface, lifting plug valve is divided into soft seal and hard seal. The basic principle is to raise the cock when it is opened. The friction between the cock and the sealing surface of the valve body can be reduced when the cock rotates 90 degrees to the full opening of the valve; When closing the valve, turn the cock 90 degrees to the closed position and then lower it to contact the sealing surface of the valve body to achieve sealing.

4. Three-way and four-way plug valves

Three-way and four-way plug valves are suitable for fluid reversing, changing medium flow direction or medium distribution. According to the requirements of service conditions, soft seal bushing or soft seal and hard seal lifting plug valve can be selected.

Ⅲ. Advantages of plug valves

1. The plug valve is used for daily operation, which can be opened and closed quickly and easily.

2. The plug valve has small fluid resistance.

3. The plug valve has the advantages of simple structure, small relative volume, light weight and easy maintenance.

4. The plug valve has good sealing performance.

5. The plug valve is not limited by the installation direction and the flow direction of medium can be arbitrary.

6.The plug valve has no vibration and low noise.

Brief Introductin of Seven Kinds of Industrial Valves
The industrial gate valve is a device that guides or regulates flow by opening, closing or partially blocking a channel. If you want to become a plumbing expert, you also need to know about industrial valves and fittings. Without a valve, there is no way to control pipeline flow.

Types of Industrial Valve
1. Butterfly valve

The Weidouli butterfly valve is designed to adjust the flow, but its control capability is limited. It is a relatively simple industrial valve, which can be operated by rotating the handle 90 degrees.

2. Check Valves

The check valve is also called NRV and only allows fluid to flow in one direction. The purpose of the check valve is to prevent backflow. There are many kinds of "retainers" that can prevent backflow in the check valve. Ball check valves and piston check valves work with small pressure. The backflow force is not enough to bring the ball or piston back in the opposite direction. The flow in the rotating check valve pushes a hinged disc that opens only to one direction to ensure that fluid does not flow backwards.

3. Industrial valve: safety valve

It is a kind of industrial valves & fittings whose installation purpose is to limit the pressure in the system. This type of angled air supply valve is strictly used to prevent overpressure that may cause damage to the system.

4. Ball valve

The ball valve has a very good closing function. Simply rotate 90 degrees to fully open or close the valve. This feature can minimize the operating time of the valve and reduce the possibility of leakage due to wear of the sealing gasket.

5. Gate valve

A gate valve is common in the industry. The gate is lifted and the fluid in the pipeline starts to flow. Gate valves are designed to be fully open or closed; they are usually used as shut-off valves to isolate pipeline systems. When the gate valve is opened, there is no blockage in the flow path, which causes little or no friction loss. When a straight fluid flow and a small limit are required, a gate valve can be used. The gate valve is usually controlled by a hand wheel, pneumatic diaphragm, electric motor or piston mechanism.

6. Globe valve

The globe valve is used to control the flow in the pipeline, and is different from the "full-pass or full-close" function of the gate valve. The globe valve is adjusted by the position of the movable disc (or plug) relative to the fixed ring seat. The port of the shut-off valve can go straight or be at a certain angle. This type of angled feed valve is usually used for corrosive or viscous fluids that are prone to solidification.

7. Industrial valve: needle valve

The needle valve is essentially a shut-off valve used to control the flow very finely. The needle valve contains a slender conical plug that can adjust the flow with high precision.

As a reliable industrial valve company, we will do our best to meet all the needs of customers.

Application of Titanium Valves(2024年01月30日)

tznt — 2024-01-30T10:46:04+0900

https://www.wsv-valve.com/application-of-titanium-valves.html

Application of Titanium Valves
1. Introduction of titanium valves

Usually people choose different types and specifications of titanium control valves according to different needs, especially in the petrochemical industry titanium valves are widely used. Because most of these industries have strong corrosive media, valves of general materials cannot withstand the corrosion of these strong corrosive media, so titanium valves that are resistant to corrosion and oxidation are needed.

2. Application of titanium valves

Valve titanium is a kind of pipeline accessories, it is a fluid control device used to change the passage section and the flow direction of the medium, and control the movement of the conveyed medium. Whether in industry, agriculture, national defense, or daily life, this fluid control equipment is inseparable.

Titanium valves, like ordinary valves, have many types and models, which can be classified into the titanium ball valve, titanium globe valve, titanium check valve, titanium butterfly valve, titanium gate valve, and other types of valves. They all have the same chemical properties and can effectively resist corrosion and oxidation. They are essential titanium valves for some special industries and special working conditions. Titanium valves made of titanium have a silver-white transition metal appearance, light weight, high strength, strong metallic luster, and excellent corrosion resistance, especially in sea water, aqua regia, chlorine and other media. Titanium valves have stable chemical properties, high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, and high strength, low density and other advantages are favored by people.

A Gate Valve and Its Advantages(2024年01月30日)

tznt — 2024-01-30T10:45:00+0900

https://www.wsv-valve.com/a-gate-valve-and-its-advantages.html

Gate Valves and Its Advantages
A surface gate valve is a wedge disc for opening and closing. The movement direction of the brake is required to be perpendicular to the direction of the fluid. It can be opened and closed completely, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the metal material is sealed and welded to improve the wear resistance. The gate is divided into rigid and elastic gates and is widely used in chemical, petroleum, light industry, hospitals, environmental protection, etc.

Ⅰ. How does a gate valve work

How does a gate valve work? The opening and closing disc of the gate valve is the wedge disc, which has two sealing surfaces. The most commonly used mode is that the two sealing surfaces of the gate valve form a wedge. The wedge angle depends on the valve parameters, which is usually 5°, and is 2°52' when the medium temperature is not high. The gate of the wedge gate valve can form a whole, which is called a rigid gate. It is possible to manufacture gates that can produce slight deformation so as to improve the manufacturability, and compensate for the deviation of the sealing surface angle during processing. This kind of gate is called an elastic gate. After the gate valve is closed, the sealing surface can only be sealed by the pressure of the medium. In other words, according to the media pressure, the sealing surface of the gate can be pushed into the other side to ensure the sealing of the sealing surface, which is called self-sealing. Most gate valves adopt the method of forced sealing.

Ⅱ. Gate Valve Advantages

1. The flow resistance is small. The media channel inside the valve is straight, and the flow resistance is small.

2. It is easier for it to do the opening action. Because compared with the shut-off valve, the movement direction of the gate valve is perpendicular to the direction of the medium flow, whether it is open or closed.

3. High and long opening and closing time. The opening and closing stroke of the gate is relatively large, and the elevator is carried out by screws.

4. Water hammer is not easy to occur.

5. The two sides of the channel are symmetrical, and the medium can flow in any direction from both sides, which is convenient for installation.

6. The structure length (the distance between the two connecting end faces of the system shell) is small.

7. The gate valve has simple body shape, short structure, good manufacturing technology and wide application range.

8. The gate valve boasts compact structure, good valve rigidity, soft channel, small flow resistance, long sealing surface between stainless steel and hard alloy, long service life, PTFE packing, reliable sealing, light and flexible operation.

What Are Valves? How Do They Work?

The most basic function of valves is to control, adjust or guide the flow in a system or process. Each of them has a series of characteristics to match the most suitable equipment.

Functions of valves

Valves have various functions, including:

They can start or stop flow based on valves condition

They can adjust flow and pressure in the piping system

They can control the flow direction in the piping system

They can throttle the flow rate in the piping system

They can improve safety by releasing pressure or vacuum in the piping system

Explanation of valves opening method

Although many valves can achieve similar goals, their mechanical properties are different. The way valves open and close not only affect the overall performance, but also determine the degree of flow control and the speed at which valves are operated.

Classification of valves

In addition to the mechanical movement associated with valves, the driving method also needs to be considered. In most cases, valves are divided into three categories:

Manual valves: They are usually manually adjusted. These valves are driven by manual wheels, manual level gauges, gears or chains.

Actuator valves: They are usually connected with an electric motor, an air or pneumatic system, a hydraulic system or a solenoid. These valves can be used for remote control and automation of high-precision or large-scale applications.

Automatic valves: Some valves are activated when certain flow conditions are met, such as check valves that close during the backflow process or relief valves that activate when overpressure conditions are detected.

https://www.wsv-valve.com/water-treatment.html

Water treatment control valves of good corrosion resistance and reliably sealing. Ball valves or sewage treatment butterfly valves are usually used in water treatment to control the flow, opening, and closing of water, thus achieving zero leakage and long service life. Valve material depends on the nature of sewage, such as whether it contains acidity and alkalinity.

Wastewater Treatment Industry
Wastewater is the water supply of a community after it has been soiled by use. It may contain human and household wastes, industrial wastes as well as groundwater. The wastewater treatment process can range from relatively simple to very complex. Because wastewater from households or agriculture does not contain the same substances as industrial wastewater. In the food processing industry, the composition of wastewater is different from that in the chemical industry. Wastewater is most often collected by gravity sewers and then lifted by pumps to allow it to flow through the treatment process. Raw sewage is, by its very nature, a difficult material to control.

Angle-type control valves are the most critical control valves used in the discharge pipe between autoclave in oxygen pressure leaching workshop and flash tank, being able to affect the normal operation and stability of the device as well as the production cost.

Angle-type control valves are the best choice for mining, smelting, chemical industry equipment in the pipeline. Weidouli Valves company researched “Angle type control valve” which has a strong anti-erosion performance. In order to meet the customer's use requirements, our angle-type control valves have made reasonable designs in structure and material selection.

The Structure and Material Selection of Angle Type Control Valves

Valve chamber cushioning design

When the pulp passes through the valve core, it must first be decompressed to facilitate the cushioning effect. With cushioning design, the inner chamber can reduce the medium pressure instantaneously, and the pulp will not wear and wash the valve body too heavily.

No dead band design at turning position

The no-dead band design can keep the fluid flowing smoothly, without frontal erosion of shell walls and inner parts due to sharp turning.

Special Materials

The plug and seat are made of WSV alloy material with strong cavitation resistance, which can effectively reduce the damage of the plug and seat caused by cavitation. Therefore, our angle-type control valves can work longer in a high-speed flow medium.

Hawking Metal Surface Processing Technology

The surface roughness of the elements processed by the Hawking Machine is less than Ra0.2, which improves its surface hardness and wear resistance, reduces the wear of sealing filler and the valve torque, and makes the seal of the dynamic sealing part more reliable.

Spring-loaded to compensate seal automatically

The Belleville spring is used to load the connecting bolt between packing and gland flange to prevent an abnormal change of pressure and temperature in the pipeline. The Belleville spring can automatically compensate for and protective sealing.

tznt — 2023-03-29T10:53:35+0900

https://www.wsv-valve.com/products/duplex-plug-valves.html

Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel.

Strength: Duplex stainless steels are about twice as strong as regular austenitic or ferritic stainless steels.

Super duplex valves are used in many industries such as petrochemical, chemical equipment, food processing, oil, and gas.

Corrosion Resistance Of Duplex Plug Valves
As with all stainless steel, corrosion resistance depends mostly on the composition of the stainless steel. For chloride pitting and crevice corrosion resistance, their chromium, molybdenum, and nitrogen content are most important. Duplex stainless steel grades have a range of corrosion resistance, similar to the range for austenitic stainless steels, i.e from Type 304 or 316 (e.g. LDX 2101©) to 6% molybdenum (e.g. SAF 2507©) stainless steels.

The Cost Of Duplex Plug Valves
Duplex stainless steels have lower nickel and molybdenum contents than their austenitic counterparts of similar corrosion resistance. Due to the lower alloying content, duplex stainless steels can be lower in cost, especially in times of high alloy surcharges. Additionally, it may often be possible to reduce the section thickness of duplex stainless steel, due to its increased yield strength compared to austenitic stainless steel. The combination can lead to significant cost and weight savings compared to a solution in austenitic stainless steel.

Duplex Plug Valves applications
Duplex valves are versatile and can be used in various applications where reliable and efficient flow control is required, for example: chemical processing, oil and gas pipelines, water treatment, power generation and so on.

Working Principles of Butterfly Valves(2023年01月24日)

tznt — 2023-01-18T15:16:26+0900

https://www.wsv-valve.com/working-principles-of-butterfly-valves.html

How Does a Butterfly Valve Work?

The butterfly valve opening and closing part is a butterfly plate, which is driven by the valve stem and rotates 90° around its own axis in the industrial valve body to achieve the purpose of opening and closing or adjustment. It has simple structure, small size, short structure length, small size, light weight, which is suitable for large-diameter large butterfly valves.

Ⅰ. The butterfly valve working principle

The butterfly valves are usually less than 90° from fully open to fully closed. The butterfly valves and the butterfly stems have no self-locking ability. For the positioning of the butterfly plate, a worm gear reducer must be installed on the valve stem. The use of worm gear reducer can not only give the butterfly plate self-locking ability, making the butterfly plate stop at any position, but also improve the operation performance of the valve. The characteristics of the industrial butterfly valves: high temperature resistance, high applicable pressure range, large nominal diameter of the valve, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. The large high temperature butterfly valves are made of steel plate welding, and are mainly used for flue ducts and gas pipes of high temperature media.

Ⅱ. The structural characteristics of the butterfly valves

1. The butterfly valves have the characteristics of simple structure, small size, light weight, low material consumption, small installation size, rapid switching, 90° reciprocating rotation, and small driving torque. They are used to cut off, connect, and adjust the medium in the pipeline. They have good fluid control characteristics and close sealing performance.

2. The butterfly valves can transport mud, and the accumulation of liquid at the pipe mouth is the least. Under low pressure, good sealing can be achieved with good adjustment performance.

3. The streamlined design of the butterfly plate makes the fluid resistance loss small, which can be described as an energy-saving product.

4. The valve stem is a through-rod structure, after quenching and tempering and it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valves are opened and closed, the valve stems only rotate and do not move up and down. The packing of the valve stem is not easy to be damaged and the sealing is reliable. It is fixed with the butterfly plate cone pin, and the extended end is designed to prevent the valve stem from collapsing when the connection between the valve stem and the butterfly plate is accidentally broken.

5. Connection methods include flange connection, butt connection, butt welding connection and lug butt clamp connection.

Working Principle of Globe Valve(2023年01月23日)

tznt — 2023-01-18T15:15:50+0900

https://www.wsv-valve.com/working-principle-of-globe-valve.html

The globe valve, also called the gate, is one of the most widely used valves. The reason why it is popular is that the friction between the sealing surfaces is small during the opening and closing process, it is more durable, easy to manufacture, the opening height of it is not large, and it is convenient to maintain. It is not only suitable for medium and low pressure, but also suitable for high pressure.

1. The closing principle of the globe valve
Relying on the pressure of the valve stem, the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the flow of the medium. The valve "Three Chemicals" once stipulated that the flow direction of the globe valves shall be from top to bottom, so there is a directionality during installation. The structural length of the globe valve is longer than that of the gate valve, and at the same time, the fluid resistance is large, and the sealing reliability is not strong during long-term operation.

2. The role of the globe valve
As one of the most important shut-off valves, the globe control valve plays an important role in the aerospace field. As an important component of aerospace equipment, the globe valves realize the functions of medium transportation, cutoff and adjustment, and its sealing performance directly affects the safe and reliable operation of aerospace equipment. The study of the influencing factors and influence rules of the sealing characteristics of typical globe valves have guiding significance for the structural design of the valve sealing pair, thereby improving the sealing performance and reliability of the valve.

3. Working principle and characteristics of the globe valve
The valve plays an important role in cutting and throttling the medium in the pipeline where it is located. Globe valve, as an extremely important cut-off valve, is sealed by applying torque to the valve stem, and the valve stem applies pressure to the valve disc in the axial direction, so that the sealing surface of the valve disc and the sealing surface of the valve seat are tightly fitted, it is achieved by preventing the leakage of the medium along the gap between the sealing surfaces.

The seal of the globe control valve consists of the disc sealing surface and the valve seat sealing surface. The manual valve stem drives the valve disc to move vertically along the centerline of the valve seat. During the opening and closing process of the globe valves, the opening height is small, which is easy to adjust the flow, and it is convenient to manufacture and maintain, and the pressure is applicable to a wide range.

Compared with another commonly used cut-off valve in industrial production - the noisy valve. Structurally, the globe control valve is simpler than the former, and is easy to manufacture and maintain. In terms of service life, the sealing surface of the globe valve is not easy to wear and scratch, and there is no relative sliding between the valve disc and the sealing surface of the seat during the opening and closing of the valve, so the wear and scratches on the sealing surface are small, then the service life of sealing is improved. In addition, during the fully closed process of the globe valve, the valve flap travel is small, and its height is smaller than that of the noisy valve.

Why Close the Discharge Valve Before Starting the Centrifugal Pump?(2023年01月22日)

tznt — 2023-01-18T15:15:18+0900

https://www.wsv-valve.com/why-close-the-discharge-valve-before-starting-the-centrifugal-pump.html

Reasons for closing the discharge valve
The starting current can be reduced by closing the discharge control valve.

The current will be very high when any motor starts. When the pump is started with an open discharge valve, the discharge head will have greater resistance to the pump. Therefore, the motor must give the pump a larger starting torque, which means that the motor needs to draw more current.

If the pump discharge valves are closed when the pump is started, it means that there is no discharge head and minimum resistance to the pump, and therefore the output current is the smallest. Although the current is greater than the normal value when the motor starts, closing the discharge valve of the centrifugal pump can avoid additional load on the pump.

Situations when the discharge valve can be opened
The nab discharge valves can be opened when there is a check valve. If there is pressure on the discharge side of the centrifugal pump without a check valve when starting, the discharge valve should be closed. With a transparent plastic pipe, leakage can be easily found. It should be used with clear PVC fittings to perform well. It's good to work with clear PVC pipe manufacturer to solve problems together.

Risks of the unclosed discharge valve
Thinking from another aspect, if there are pressures at the discharge end of the pump, it may flow back into the pump before starting. And it will cause backward rotation, which can attract more current and cause damage to the pump. Therefore, it can be prevented by closing the discharge valve of the centrifugal pump when it starts.

When Should We Avoid Using Metal Hard Seal Butterfly Valves(2023年01月19日)

tznt — 2023-01-18T15:13:40+0900

https://www.wsv-valve.com/when-should-we-avoid-using-metal-hard-seal-butterf.html

The sealing pair of the Butterfly Valves usually adopts an elastic sealing material such as rubber or plastic and a metal-to-metal sealing pair, and also partially uses a fluorine-lined or ceramic sealing pair. When used as a shut-off valve, the soft seal butterfly valve seal performance is much better than the metal hard seal butterfly valves.

Metal sealed butterfly valve, although able to adapt to higher operating temperatures, have a longer service life than soft seals, but metal to metal seal valve are difficult to completely seal, so they are generally used for throttling. In the domestic valve manufacturers, due to the different structural forms of the sealing pair, when the metal dn150 hard seal butterfly valve is used as a shut-off valve, the sealing performance is also different.

What Is The Difference Between Gate Valve And Globe Valve?(2023年01月18日)

tznt — 2023-01-18T15:12:47+0900

https://www.wsv-valve.com/what-is-the-difference-between-gate-valve-and-globe-valve.html

What Is The Difference Between Gate Valve and Globe Valve?

It is important to understand the difference between the gate valve and the valve globe type when you need to choose valves. They are both popular valve types and even look similar, but they are used in completely different places.

Basic knowledge of the gate valve

The gate valve can be used to start and stop the flow, but it cannot adjust the flow level. However, they are actually used to isolate or connect liquids. Part of the flow is not ideally managed through the gate valve because it will damage the gate valve and cause vibrations.

The name comes from the operation way, a gate that slides between valve seats at right angles to the fluid flow. The shape of the gate can be wedge, knife or parallel.

Basic knowledge of the globe valve

The globe valve can be used to start, stop and adjust the flow, and the name comes from the shape of the valve body. The tapered plug enters and exits in the fluid flow during operation. The flow rate depends on the distance between the plug and the valve seat. It is necessary for operators to be careful and not to turn the valve stem too far, as this will damage the valve seat.

It provides greater resistance to fluid flow and has a higher pressure drop even when the valve is fully opened. The bronze pressure regulator also has a great performance in the pressure-reducing process. Apart from that, the OEM brass ball valve also has a good flow regulation function.

The difference between gate valve and globe valve

Physically, the gate valve is higher than the globe valve when they are fully opened, and the gate valve is more likely to cause wear of the valve seat and valve disc than the globe valve.

A major difference between the gate valve and the globe valve china is that the former can be installed in different directions, while the latter can be installed in only one direction.

The gate valves should be installed where the valve can be fully opened and closed. If it is over-tightened, there will be risks of twisting the gate valve.

Usually, the globe valve has better sealing performance and longer service life than the gate valve. And it is more expensive than a similar-sized gate valve, but the extra cost is worth it in the case when throttling is required.

Rotary motion is a kind of action of control valves, its actuator receives the control signal and turns the signal into displacement thrust or angular torque to control the opening and closing of the valve.

Rotary motion control valves have a valve disc driven by the stem to make an angular rotational action perpendicular to the stem, generally in a 90-degree range of reciprocal rotational motion.

Rotary motion control valves contain ball valves, butterfly valves, plug valves, etc.

Rotary motion control valves are widely used in petroleum, chemical, electric power metallurgy and other industries, with detection instruments, can play a role in preventing accidents, when the instrument detects a dangerous signal, the angle-stroke switching valve can immediately act to cut off the media supply to prevent malignant accidents from occurring.

Features Of Rotary Motion Control Valves

1. From the flow path, the rotary control valve is straight through the flow path, more simple.

Small flow resistance, large Kv value(1.5~3 times larger).
Medium straight through, "self-cleaning" and good anti-blocking.
Small size and lightweight (50%~80% lighter).
Small size, good appearance.

2. From the valve disc rotation structure, the defects of the rotary globe control valve are reduced.

Valve disc rotation media leakage outward is difficult, rotation friction is small, can be used to seal better performance of the packing to increase the seal lifetime arrival at 2 ~ 3 times.
Due to the force arm is small, the torque is small, the allowable pressure difference is large.
The rotary globe valve disc is a spherical surface, it with good sealing and small leakage.
Good erosion resistance. The valve disc is in the valve cavity inside, avoiding direct media erosion.
Good elimination of the upper and lower resonance.

Types Of Rotary Motion Control Valves

Control Ball Valves
Weidouli Control Ball Valves contain an On-off control ball valve(O type ball design) and a Control Segment ball valve(V type ball design).

Plug valve is a closed piece or plunger-shaped rotary valve, by rotating 90 degrees to make the valve plug on the channel port and the valve body on the channel port connected or separated, to achieve the opening or closing of a valve.

Its plugs can be cylindrical or conical in shape. In cylindrical plugs, the channel is generally rectangular; in conical plugs, the channel is trapezoidal. These shapes make the plug valve china lightweight. It is most suitable for use as a cut-off and switching medium and for shunting, but depending on the nature of the application and the corrosion resistance of the sealing surface, it may sometimes be used to throttle the flow. It is the ideal product with plug valve advantages of deposit-free, anti-crystallization, anti-corrosion, and anti-high temperature and high pressure for pipe systems.

There are two typical types of plug valves, which are lubricated and non-lubricated. The seat is an integral part of the body in terms of lubricated plug valve. For non-lubricated plug valve, there will be lined and sleeved type, with soft plug valve material to improve leakage tightness of the valve.

The pure nickel ball valve have a small flow resistance, which is one of the small fluid resistances of all nickel valves. Even for a reduced bore ball valve, the fluid resistance is quite small.

Corrosion Resistance Characteristics of Nickel Ball Valves

The hand ball valve has good sealing performance. The pure nickel ball valve seat (seal ring) is generally made of an elastic material such as Teflon, which is easy to ensure the seal, and the sealing force of the ball valve increases as the medium pressure increases.

The hand operated valve stem seal is reliable. When the ball valve is opened and closed, the valve stem only rotates by 90°, so the packing seal of the valve stem is not easily damaged, and the sealing force of the valve stem inverted seal increases with the increase of the medium pressure.

The opening and closing of the pure nickel ball valve only makes 90° rotation, so it is easy to realize automatic control and remote control.

Whether the pure nickel ball valve can resist the corrosion of the working environment medium, the key lies in the chemical stability of the "passive oxide film" on the surface in the corrosive medium.
