Flange Cryogenic Check Valve DN10-25mm PN32MPa for LNG LO2 LN2 Applications -196℃ to +80℃
Stainless steel flange cryogenic check valve with straight-through design for extreme low-temperature applications. Features PN32MPa pressure rating, -196℃ to +80℃ temperature range, and compliance with GB/T24925-2010 standards. Ideal for LNG, LO2, LN2, and LAr systems with custom options available. ISO 9001 certified manufacturer with comprehensive testing.
Flange type cryogenic stainless steel check valve designed for straight-through flow applications in extreme low-temperature environments.
During operation, the medium flows in the designated direction. When flowing forward, the valve disc opens due to medium pressure. During reverse flow, the valve disc seals tightly against the valve seat through combined action of disc weight and reverse medium pressure, effectively preventing backflow.
