Back pressure/relief valves

Griffco Unibody back pressure and 2-port pressure relief valves feature single-piece construction, with union connections machined together with the valve body. Designed for hard-to-seal or problematic pumping systems, they are available with PVC and CPVC construction in sizes from 1/2 to 1 in. (DN 15 - DN 25). Used in chemical-feed, metering and dosing pump systems, the valves include no threads, gaskets, glue or welds.
