Product Description

Metal to Metal Seat Trunnion Ball Valve

High Temperature Service
General soft seat ball valve working temperatureis limited uo to 400° F, but metal-seat ball valves are guaranteed for a maximum service temperature of 800° F.

Low Pressure Reliable Sealing
NIPO metal-seat ball valves adopt seat spring structure, which can push upstream seat tightly against the ball surface creating a reliable sealing even if extremely low pressure

Pressure Test
Metal-seat ball valves maximum allowable seat
Leakage:
Air: ANSI/FC 170-2 CLASS V

Absolute Fire Safe Guarantee
Metal-to-metal contact is designed between ball and seat, where is unconditional fire safe function. Flexible graphite gasket can prevent fluid leakage from between body & seat or body & bonnet even if high temperature environments to reach fire-safe purpose. In addition, other sealing components such as stem packing can also reach fire-safe function and prevent external leakage. So all parts of valve will not be damaged by high temperature service.

Blow-out Proof Stem & Anti-Static Device
As general ball valves, metal-seated ball valves are provided with blow-out proof stem &anti-static device.
