Cryogenic Service

Almost all Butterfly 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. If required by the customer, specific Cryogenic Tests are performed to verify the behaviour of valves sealing capability, emissions vs the ambient.
