Cryogenic Service: Almost all STEELSTRONG Check Valve 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, emissions vs the ambient.
