Valve for medium with temperature of -40℃ to -196℃ is called cryogenic valve. Cryogenic valve includes cryogenic ball valve, cryogenic gate valve, cryogenic globe valve, cryogenic check valve and cryogenic throttle valve. It’s mainly for ethylene, liquefied natural gas device, natural gas LPG LNG storage tank, air separation equipment, petroleum and chemical end gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tank and tanker and other device. The output low temperature liquid medium is not only flammable and explosive, it’s gasified when heating-up, and the volume expands hundreds times after gasification.

Application & Function:
Cast steel Gate valves are primarily used for stop valves fully opened or fully closed. They are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the flow. Gate valves usually have a minimum pressure drop when fully open, provide tight shut-off when fully closed, and remain relatively free of contamination buildup.

Accessories:
Accessories such as gear operators, actuators, bypasses, locking devices, chain wheels, extended stems and bonnets for cryogenic service and many others are available to meet the customers’ requirements.
