NJ Stainless Steel Globe Valve

Uses: NJ check valves are used for safe shutoff of pipelines, featuring resistance to high temperature and fire in the shutoff state.

Features: 1) Hardened disk contributes to long life of the valves; 2) 100% gas tightness test, applicable to various gases; 3) stem PTFE packing seal is compensated with a disc spring to ensure good tightness in high or low temperature applications.
