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 the valve body and the 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 of 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.

Advanced hardening technologies have been adopted in producing ball and seat, such as Ultron-sonic spray coating, nick base spray welding, surface specially hardening, stellite spray welding and so on. The application temperature may up to 540ºC, the maximum is 980ºC. The surface material also possesses good resistance properties of friction and impact.
1. Valve stuck prevented under high temperatures.
2. Excellent tightness functions.
3. An entire fire-safe structure.
4. Natural anti-static structure
6. Double block and bleed function.
