Low Temperature and Cryogenic Valves

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.

• Unique loose flange bolted bonnet design allows for thermal expansion and contraction and eliminates leakage at the bonnet gasket
• PTFE/PCTFE seal to ensure tight shut off at all times
• Designed and engineered specifically for cryogenic service
