Wafer Ball Valve with simple structure, small size and light weight, more, only consists of a few parts. Moreover, it can be quickly operated by rotating 90°, and the item is with good fluid control characteristics. When the ball valve is in the fully open position, the thickness of the valve plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small.

Application
Wafer Ball Valve is widely used in: chemical, petrochemical, smelting, pharmaceutical, food and other industries in SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid The medium is used as a regulating and shut-off device on the pipeline.
Strength of Ball Valve
1. The unique design of the eccentric makes the frictionless transmission between the sealing surfaces, which prolongs the service life of the valve.
2. The elastically seat generated by torque.
3. Ingenious wedge design makes the valve have a tighter and tighter automatic sealing function, with compensatory and zero leakage between the sealing surfaces.
4. Small size, light weight, light weight and easy to install.
5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
6. Replacement seat material can be applied to a variety of media.
