Stainless Steel Flanged Ball Valves


Stainless steel flanged ball valves can be closed tightly only with a 90-degree rotation and a small torque. It can be used for pipe opening and closing, throttling or flow adjustment in harsh environments.


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

2.Simple structure, small size and light weight.

3.All metal parts come available in stainless steel with superior performance against the corrosion in harsh environment.

4. It only need rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Convenient maintenance with replaceable seat and packing. 

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface.
