Features of forged floating ball valves are as follows: 

Principle of the forged steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.

1) Anti-fire safe design: API 6FA, API607

2) Anti-static device

The static-conduction spring is set between the stem and the ball, the stem and the body. Thus static electricity is conducted to ground    and system safety is secured.

3) Low torque in operation

4) Free leakage of body Sealed construction

The connective position of valve body and bonnet is double sealed by gasket and O-ring, on this base, such factors as fire, high temperature, shock and uneven opening or closing of the torque all can’t induce external leakage.

5) Automatic body cavity relief

When the body pressure going up un-normally as the unstable factor, the trunnion ball valve downstream seat will be pushed by un-normal pressure, and the release the un-normally pressure automatically, it doesn’t damage to the sealing of upstream seat.

6) The valve structure can be 2 pieces or 3 pieces.
