Key Specifications/Special Features:
Low pressure reliable sealing:
Air: ANSI/FC170-2ClassV
Fire safe guarantee: Absolute firesafe design.
Metal to metal contact is designed between ball and seat, where is unconditional fire safe function.
Flexible graphile gasket can prevent fluid leakage from between body and seat or body and 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 and anti-static device.
High temperature service:
General soft seated ball valves working temperature is limited up to 400°F, but metal-seated ball valves are guaranteed for maximum service temperature of 800°F.Low pressure reliable sealing:
Metal-seated ball valves adopt seat spring structure, which can push upstream seat tightly against the ball surface creating a reliable sealing event if extremely low pressure.
Pressure test:
