Butterfly Valve

Butterfly Valve

Butterfly valves have been used in numerous industries to improve processes and applications. Butterfly valves regulate material flow within large pipe diameters by rotating a disc a quarter-turn at a time.

Hightech is well known for its extensive experience in manufacturing Butterfly valves for the hydrocarbon, energy, and process industries.

Cryogenic Service

Almost all Hightech 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 the minimum design temperature required by the Customer. Depending on the requirements of the customer, specific cryogenic tests are performed to determine the valve's sealing capability and emissions.
