Wafer Ball Valve
The ball valve with clamp connection has the characteristics of natural anti-static structure, anti-misoperation structure and reliable sealing of valve stem. The valve body adopts an integral structure. Through precise processing and assembly, the ball core is loaded from one end, and the compression ring is tightened to keep good contact and sealing between the two soft sealing seats and the ball core. The valve pressure ring inner gasket is also well sealed so that the leakage of the valve is zero. Because of the integral structure of the valve body, so the valve to achieve ultra-short flange distance, the weight of the machine greatly reduced, only about 50% of the same kind of ordinary ball valve.

Structural characteristics
1. eccentric design makes friction free transmission between the sealing surfaces extend the service life of the valve.
2. elastic seal is generated by torque.
3. The clever wedge design makes the valve more closed and tighter automatic sealing function. The sealing surfaces are compensatory and zero leakage.
4. small size, light weight, easy operation and easy installation.
5. pneumatic and electric devices can be configured to meet the needs of remote control and program control.
