Product Description

Features of forged trunnion ball valves are as follows: 

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) Anti-blow out design

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) Low torque in operation

6) Double block&bleed(DBB)

7) Emergency sealing

8) 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.

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