The Advantages of Two Pieces Ball Valve

Two pieces ball valve is a new type of ball valve, it has its own unique advantages of the structure, such as the switch without friction, low opening and closing torque, and its seal is not easy to wear. This reduces the specification of the actuator. Small diameter is easy to install, also can realize the tight cutting and adjustment of the medium, widely used in the equipment.

The characteristics of two pieces ball valve are listed as bellow:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe with the same length.

2. Simple structure, small size, light weight.

3. Close tightly and reliable seal, the ball valve sealing surface material widely adopts metal, PTFE, EPDM, EPR and so on. Cause it has high sealing performance, it has been widely used in various industries, even the vacuum system.

4. Convenient operation; rapid opening and closing; as long as 90 degree rotation, it can achieve from fully open to fully closed, and it facilitates remote control.

5. Easy maintenance, simple valve structure, seals are generally moved, demolition and replacement are more convenient than before.

Under the fully open or fully closed condition, the ball and valve seat sealing surface is isolated from the fluid. When the medium pass through, it will not cause erosion of the valve sealing surface. This kind of ball valve has a wide range of applications. Its diameter can be a few millimeters up to few meters. Also applied in high pressure and high vacuum condition. When the ball is rotated 90 degrees,the surface of ball should be completely spherical at the inlet and outlet port, then the flow is cut off.
