Metal to metal seat ball valve specifications

High Temperature Service
General soft seated ball valves working temperature is limited up to 400°F, but metal-seated ball valves are guaranteed for a maximum service temperature of 800 °F.
Low Pressure Reliable Sealing
YIHUAN metal-seated 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-seated ball valves maximum allowable seat leakage:
Air: ANSI/FCI 70-2 Class V
Absolute Fire Safe Guarantee
YIHUAN metal-seated ball valves are absolute fire safe design. 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 & adapter 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 the valve will not be damaged by high temperature service.
Blow-out Proof Stem& Anti-Static Device
As general ball valves, YIHUAN metal-seated ball valves are provided with blow-out proof stem& anti-static device.
