Cryogenic Gate Valves

Services that handle fluids at sub-zero temperatures present several technical challenges. AIL’s specially-adopted, extended-bonnet gate and globe valves provide the right solution for such low-temperature and cryogenic services. AIL offers a range of gate and globe valves (as well as check valves) for low temperature and cryogenic services, used in processing, storage and transportation of liquefied gases such as Ethylene, LPG, LNG, Hydrogen, Helium, Oxygen, Nitrogen and Argon. Low temperature services of up to -460C are covered by low-temperature carbon steels like LCB and LCC materials. Cryogenic services at -1960C are covered by stainless steel grades like CF8M and CF8. AIL Cryogenic Gate and Globe Valves are available in ASME Class 150, Class 300 and Class 600 ratings. Refer page 3 for detailed manufacturing programme. Extended Bonnet Optional extended bonnet with vapour column length according to BS 6364 and or customer specifications is furnished. The vapour column allows the stem packing to be functional by keeping it away from the cryogenic fluid. Testing and Standards AIL Cryogenic Valves are type-tested as per valve standards and specifications of leading oil companies as part of the design verification process.
