High Temperature Service

General soft seated ball valves working temperature is limited up to 400F , but metal-seated ball valves are guaranteed for a maximum service temperature of 800 F.

Low Pressure Reliable Sealing

Enine 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.

Absolute Fire Safe Guarantee

Enine 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 affected by high temperature service.

Blow-out Proof Stem& Anti-Static Device

As general ball valves, Enine metal-seated ball valves are provided with blow-out proof stem& anti- static device.
