Check Valves


Check Valves (A400)

NPS: 2″ – 48″

Compact Forged Valves are multiple purpose valves for use as drain, vent and instrument connections. Check valve is used to prevent pressure increase at opposite direction. Globe valve is used for controlled throattling of the flow. They should be preferred where larger differential pressure exists ot where the flowing fluid has to be exhausted to atmosphere. Gate or Ball types are to be used when tightness is required.
