The ball core of a one-piece ball valve ss316 should be inserted from the threaded end of the valve body. If the diameter of the ball core runner is processed to the same value as the nominal diameter, the outer circle diameter of the ball core should be larger than the outer circle of the reduced diameter ball core. As a result, the ball core cannot be inserted into the valve body from the valve body thread, because the diameter of the outer circle of the sphere exceeds the inner hole size of the valve thread.

For the one-piece internal threaded ss ball valve, due to the size limitation of the valve body structure, the full bore ball core cannot complete the assembly of the ball core. Not loaded into the valve body. Therefore, the core can only be used in the form of reduced diameter.

QSL1T-2 Reducing Bore 1PC Ball Valve FAQs
What Is The Difference Between One-piece Ball Valve And Two-piece Ball Valve?

(1) The working principle is different: the working principle of the one-piece ball valve is the mechanical pressure of the stem; the working principle of the two-piece ball valve is to make the valve unblocked or blocked by rotating the valve core.

(2) The valve body is different: the one-piece ball valve is fixed by a plug head; the two-piece ball valve is fixed by two pieces of valve body sandwiching the ball. The maintenance is relatively complicated, and the tightness of the bolt in the middle is very important.

(3) The closing parts are different: the closing part of the one-piece ball valve is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing of a valve; while the two-piece ball valve has no special requirements.
