Almost all Dual Plate Check Valve types can be designed in a special version suitable for cryogenic service. In this case, all the materials and technical features are designed to withstand minimum design temperature required by the Customer, down to Cryogenic -196°C. If required by the customer, specific Cryogenic Tests are performed to verify the behaviour of valves sealing capability and emissions etc. vs the ambient.
