Product Description
Product Overview
Emergency cryogenic shut-off valve constructed from SS304 stainless steel, designed specifically for LNG (Liquefied Natural Gas) applications. Available in sizes ranging from DN10 to DN200mm with pressure ratings up to PN4.0MPa/CL300.
Manufacturing & Quality Control
Liang Chuan employs strict manufacturing processes and specialized equipment for low-temperature valve production. All components undergo cryogenic treatment in cooling media for 2-6 hours to release stress and ensure material stability at extreme temperatures. This prevents leakage due to thermal deformation during operation. Assembly includes thorough cleaning to remove oil residues, maintaining optimal performance in cryogenic environments.
Installation & Usage Guidelines
- Ensure piping system is thoroughly cleaned before installation
- Install with flow direction arrow aligned with fluid direction
- Maintain degreased condition during storage and installation
- Open all valves after pipeline construction to remove residual debris
- Perform degreasing for systems requiring oil-free operation
- Operate valves slowly during opening and closing cycles
- Replace worn components (valve disc, seat, stem) promptly
- Always use new gaskets and sealing materials during maintenance
