Product features

The pneumatic three piece ball valve is composed of a three piece ball valve and a pneumatic actuator. It adopts a three-stage structure. It is composed of left and right valve bodies and the middle valve body. It is connected by bolts into a whole. It has the advantages of simple disassembly and easy maintenance. The pneumatic three piece ball valve can be divided into double action and single action according to the action form. The single action form has the spring return function, which can automatically return to the open or closed state in case of failure or no air source. The pneumatic three piece ball valve uses compressed air as the power source to drive the valve core to rotate back and forth at 0-90 degrees, which can realize the opening and closing of the valve. It is widely used in various industries and is a common control valve.
 
Advantages of pneumatic three piece ball valve:
 
1. Three section valve body, threaded connection, compact structure, light weight, can be used from high vacuum to high pressure.
2. Compact shape, saving installation space, especially suitable for working conditions with small mechanical volume and narrow space.
3. The threaded three piece pneumatic ball valve has reliable sealing, long service life, quick switch action, convenient maintenance and easy disassembly.

Three piece ball valve and one piece and two piece ball valve difference:
 
The one-piece ball valve is an integral valve body, which is fixed by a plug. It is an integral valve body and is commonly used for small valves.
The two-piece ball valve is composed of two parts. It is fixed by two valve bodies clamping the ball. The maintenance is relatively complicated. The tightness of the screw in the middle is critical, which is related to the possibility of leakage.
The three piece ball valve consists of the left and right valve bodies and the middle valve body, and is clamped by the neck flanges on both sides. Its pressure is higher than that of the other two types of ball valves.
Generally, the internal screw ball valve is mostly one piece or three piece, while the three piece ball valve is generally precision cast valve, and the two piece valve is mostly used for flange valve.
