Gate Valve

gate valves are used extensively throughout the refineries,hydrocarbon,energy and process industries.

cryogenic service: gate valves 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 production valves in terms of valve torque, sealing capability, emissions vs the ambient
