Product Description

API Flanged End Cryogenic Gate Valve (GADZ41H)

Product Description

Cryogenic Valve is often used for the working condition with very low temperature.Generally, such valve is often designed with Extended Stem or Bonnet so as to prevent the Stem Packing being damaged because of low tempeature. Besides this, the valve is also made with the special material and done cryogenic treatment so as to make it resist low temperature.

Specification

Cryogenic Valve Material selection:

1. LCB Material is suitable for working temperature up to -46 Deg C.
2. LCC Material is suitable for working temperature up to -49 Deg C.
3. CF8 Material is suitable for working temperature up to -110 Deg C.
4. CF8M Material is suitable for working temperature up to -196 Deg C.
