Plast-O-Matic Valves”Series PRHM thermoplastic pressure regulator is capable ofconverting inlet pressures up to 150 PSI to a predetermined maximumdownstream pressure ranging from 5 PSI to 125 PSI. Unique to theseregulators is the rolling diaphragm seal, which isolates the springchamber from the downstream pressure sensing liquid and assuressensitive, smooth, accurate performance. Other important featuresinclude all-molded body construction, which eliminates internal leakagethat could cause a malfunction, and a heavy-duty shaft seat towithstand pressure surges. The new valve also includes a built-in portfor a pressure gauge. Regulators are available in _”, _” and 1″ pipesize, in Grade 1 Type 1 PVC.
