CRYOGENIC BUTTERFLY VALVE
The PROVAL valve utilizes a double offset disc design, coupled with a flexible metal seat design which provides an independent static and dynamic seal. Seat design allows for self-centering on the disc. The valve is capable of achieving tight shut off at cryogenic temperatures, bidirectional sealing, and is firesafe.
The use of an all metal seat design, allows the valve to withstand a partial or full burn in a condition. The metal seat design provides a fire safe seal, all the time; and is not dependent on fire intensity.
THE PROVAL CRYOGENIC BUTTERFLY VALVE range has been extensively used on applications including low temperature gas and liquid service(Liquid Nitrogen, Oxygen & Hydrogen)
LNG Tankers on process duties, Onshore LNG Production Plants and Onshore Gas Distribution Terminals.
