Cryogenic valves are used in various application areas, including natural gas processing and blowdown systems.
These valves operate at temperatures below -50F and down to -320F and below. The extreme low temperatures which valves in Cryogenic service see require special attention be paid to the selection of materials including metallic and non-metallic components.
Cornerstone produces valves suitable for cryogenic services in a full range of pressure classes – all the way up to API 10000. Services include gas and liquefied gasses. Testing is typically performed in a liquid nitrogen bath with helium as the test media.
Cornerstone Cryogenic Valve Design Features:
A company producing and processing natural gas in North Africa’s punishing conditions required a set of carefully designed and fully tested valves to give consistent shut-off results when operating at -150°F in a fractionating plant.
Specially engineered Cornerstone valves were created and rigorously tested by an independent valve testing company. The customer’s engineer witnessed the full valve testing sequences in a submerged liquid nitrogen bath. The 6" valves were the tightest the facility had ever tested in their many years of performing cryogenic tests.
Today in North Africa, Cornerstone valves perform as flawlessly as in the lab.
