8500 Triple Offset Cryogenic Butterlfy valves for Cryogenic

Product Description

CRYOGENIC BUTTERFLY VALVES

Severn’s Cryogenic valve range is developed from our years of control valve knowledge and experience. We have developed our 8100, 8300 and 8500 ranges for cryogenic applications. Open or closed extension bonnets are available for all our valve products, ensuring the gland packings are located away from the line media. By utilizing the principles of our 8100, 8300 and 8500 valve ranges, we can offer a vast range of products, from a single offset swing clear valve, a double offset PTFE seated valve or a Triple Offset valve, all specifically tailored for cryogenic service. Clients can also choose from standard and bespoke face to face and end connection options. With access panels available on Butt Weld End designs when required.
