Thread by flange back pressure check valves offer secure connections and prevent backflow in LPG and NH3 systems, ensuring consistent performance.
Designed to provide protection of a container opening when desired flow is always into the vessel. May be used in line applications where flow must be limited to one direction. When used with the appropriate single check filler valve, the combination forms a double check filler valve suitable for use in filling of bulk storage tanks.
