PTFE Lined Ball Valve

The PTFE lined ball valve uses high-quality PTFE material and a sealing pair structure design for the valve seat cone sealing surface, which can effectively guide the operation trajectory of the opening and closing parts. It also adopts an axial fixed design. When the ball rotates 90° relative to each other to complete the entire opening and closing process, the operating torque is small, the opening and closing are smoother and more stable, and good sealing effects can be achieved.

Design Advantages

The ball and valve stem are made of integrated castings.

The surface is equipped with through holes and dovetail grooves to tightly bond the lining layer with the metal parts and should not be detached. When the valve chamber is abnormally pressurized, the valve stem will not fly out.

There is an anti-static device between the valve body and valve stem.

The explosion-proof device design of the valve stem can be selected for various harsh situations.

Low fluid resistance.
