Manual DN65 Low Temperature Socket Weld Globe Valve for LN2 -196℃ to +196℃ Temperature Range with 4.0MPa Pressure Rating
Manual DN65 low temperature socket weld globe valve designed for LN2 (liquid nitrogen) applications. This cryogenic valve features stainless steel construction and socket weld connections for reliable performance in extreme temperature environments.
- Ensure pipes are thoroughly cleaned and blown clean before installation
- Install with flow direction arrow on valve body matching fluid flow direction
- Maintain cleanliness during installation as valves are pre-degreased
- After pipeline construction, open all valves to remove residual debris
- Follow degreasing procedures for oil-free system requirements
- Operate valves slowly during opening and closing cycles
- Replace worn components (valve disc, seat, stem) immediately
- Always use new gaskets and sealing materials during maintenance
