New Cryogenic Check Valve operates at fluid temperatures down to -196°C

While the standard acceptance testing is performed at room temperature as a cost and time-saving measure, qualification testing for this check valve was performed with the valve submerged in liquid nitrogen. This testing confirmed leakage results of less than 10 SCCM of helium at -320°F (-196°C).

The Cryogenic Check Valve incorporates fitting ends per AS standards, making it easy to integrate into existing systems.

The valve’s materials were carefully selected for their compatibility with hydrogen and other fluids used at cryogenic temperatures.

In addition, the valve’s adaptable construction supports material changes to suit a wide range of environments.

Key features of the Cryogenic Check Valve:
• Temperature range: -320°F to 275°F (-196°C to 135°C)
• Pressure rating: up to 5,000psi
• Leakage: <10 SCCM helium at -320°F (-196°C)
• Lohm resistance: 85Lohms (fully open) (Cv = 0.24)
• Fitting interfaces: AS4395E04 (inlet) & AS4395E06 (outlet)
• Materials: Nitronic 50, 316 CRES, A286 CRES, cobalt alloy, polyimide seat

This product is ideal for use in aerospace and other mission-critical systems that handle ultra-low temperature fluids, such as satellite propulsion systems.

Applications include cryogenic propulsion, thrust vector control, and thermal management loops using liquid hydrogen or oxygen, as well as precision fluid control in life support and fuel management systems.
