Product Description
Product Overview
Flange Type Emergency Cryogenic Shut Off Valve manufactured in SS304 and SS316 materials, available in sizes from DN10 to DN100mm. Designed for reliable operation in extreme low-temperature environments.
Manufacturing Excellence
Liang Chuan Company employs strict manufacturing processes and specialized equipment for low-temperature valves. All components undergo cryogenic treatment in cooling media for 2-6 hours to release stress and ensure dimensional stability, preventing leakage due to thermal deformation in low-temperature conditions. Assembly includes thorough cleaning to remove oil stains and ensure optimal performance.
Installation Guidelines
- Ensure piping system is thoroughly cleaned before installation
- Align valve flow direction arrow with fluid flow direction
- Maintain clean storage conditions as valves are pre-degreased
- Open all valves after pipeline construction to flush out residues
- Perform degreasing for systems requiring oil-free operation
- Operate valves slowly during opening and closing cycles
- Replace worn components (disc, seat, stem) promptly
- Always use new gaskets and sealing materials during maintenance
