Description

The Cryogenic Gate Valve is available in two bonnet designs: Bolted Bonnet and Welded Bonnet. The Bolted Bonnet design features bolts and nuts connecting the valve body to the bonnet, utilizing wound gaskets made of 316 flexible graphite. Metal rings can be incorporated upon special request. Alternatively, the Welded Bonnet design securely welds the valve body and bonnet, ensuring a fully sealed connection. Penetration welding can also be utilized based on customer specifications.

Applicable Medium: Suitable for handling low-temperature media such as Methane, Liquid natural gas, Hexene, Carbon dioxide, Liquid ammonia, Liquid oxygen, Liquid nitrogen, Liquid hydrogen, and more.
