Pressure-Reducing Valve for High-Purity Applications

Plast-O-Matic Valves' Series PRH-U is a pressure-reducing valve for thermoplastic materials selected specifically for semiconductor, pharmaceutical, and other industries requiring ultra-high purity. The valve is constructed of a machined Kynar 740 PVDF body and metal-ion-free EPDM seals to provide the highest possible purity in a fused piping system. In addition to the ultra-pure materials, Plast-O-Matic uses a three-step cleaning process in the manufacture of this valve. This includes a proprietary pre-assembly cleanroom treatment, a post-assembly hot and cold eight-hour rinse with deionized water, and a final Class 100 clean and double-bag procedure. Spigot-type bead-and-crevice-free pipe connections are standard in sizes 1/2" through three inches and can be specified to match any major PVDF pipe supplier dimensions. Valves regulate downstream pressure from 10-125 PSI, with maximum inlet pressure of 150 PSI.
