Plast-O-Matic Valves' Series PRH-U pressure-reducing valve improves purity in a fused piping system

Plast-O-Matic Valves' Series PRH-U pressure-reducing valve is constructed of a machined Kynar 740 PVDF body and metal-ion-free EPDM seals to provide improved purity in a fused piping system. Plast-O-Matic uses a three-step cleaning process that includes a proprietary pre-assembly clean room treatment, a post-assembly hot and cold eight-hour rinse with deionized water, and a final class 100 clean and double-bag procedure.

Series PRH-U features a non-rising stem that is designed to minimize installation height. It also has a redesigned internal shaft; the smoother shape is engineered to help maximize flow capacity. All external fasteners are non-wetted and capped to prevent atmospheric corrosion.

Spigot-type bead-and-crevice-free pipe connections are standard in sizes 1/2 inch through three inches. Valves regulate downstream pressure from 10-125 psi, with maximum inlet pressure of 150 psi.
