Pressure Regulator Handles Ultra-Pure Liquids

Plast-O-Matic Valves has developed a new pressure-reducing valve using thermoplastic materials selected specifically for semiconductor, pharmaceutical and other industries requiring ultra-high purity.

Series PRH-U comprises 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. This includes a preassembly 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. Independent lab tests verify that the PRH-U has the lowest contamination levels of any PVDF pressure reducing valve currently available.

In addition to its ultra-high purity levels, series PRH-U features a non-rising stem to minimize installation height. It also has a redesigned internal shaft. The smoother shape helps to 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 ½-inch through 3 inches and can be specified to match any major PVDF pipe supplier dimensions. Valves regulate downstream pressure from 10 to 125 psi with maximum inlet pressure of 150 psi.
