Rotary Motion Control Valves

Rotary motion control is a kind of action of rotary 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 globe valve 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 Globe Valves
1. From the flow path, the rotary motion valves are 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 motion 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 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.
Rotary Motion Control Valves Applications
The rotary motion valve is used in diverse industries for precise flow control. The rotary control valve finds applications in oil and gas operations, chemical processing, power generation, water and wastewater treatment, petrochemical manufacturing, HVAC systems, mining, pharmaceuticals, food and beverage production, automotive and aerospace systems, pulp and paper processing, and marine and offshore installations. These motion control valves enable accurate regulation of fluid and gas flow rates, ensuring efficiency, reliability, and safety in critical processes. The rotary globe valve or rotary globe control valve or rotary plug control valve is essential components in a wide array of industrial processes, ensuring efficient and precise flow control in various applications across different sectors.
