Almost all HAWA 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.
- Through Conduit Gate Valves? Yes, absolutely! Engineered to client specifications with a host of customizations. This is Hawa Valves…
- Some of the 76 ESD Valves for a prestigious Offshore Project in the ME. Partial Stroking, with SIS Positioner, Quick Closing. Actuator sized at full DP. Local Controls. Challenging, but oh so satisfying!!!
- If valves could speak, what would these impressive large MOV Ball Valves tell you?
