The Series PRHM thermoplastic pressure regulator converts inlet pressures of up to 150 psi to a predetermined maximum downstream pressure ranging from 5 to 125 psi settings. The regulators feature a rolling diaphragm seal that isolates the spring chamber from the downstream pressure sensing liquid, ensuring sensitive, smooth, accurate performance. Other important 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.
