Plast-O-Matic Valves’ new Series PRHM thermoplastic pressure regulator is capable of converting inlet pressures up to 150PSI to a predetermined maximum downstream pressure ranging from 5PSI to 125PSI. Unique to these regulators is the rolling diaphragm seal, which isolates the spring chamber from the downstream pressure sensing liquid and assures sensitive, smooth, accurate performance. Other features include all-molded body construction, which eliminates internal leakage that could cause a malfunction, and a heavy-duty shaft seat to withstand pressure surges. The new valve also includes a built-in port for a pressure gauge. Regulators are available in 1/2in, 3/4in and 1in pipe size, in Grade 1 Type 1 PVC.
