The new pressure-reducing valve uses thermoplastic materials selected specifically for semiconductor, pharmaceutical, and other industries requiring ultra-high purity. The Series PRH-U is constructed of a machined Kynar 740 PVDF body and metal-ion-free EPDM seals to provide high purity in a fused piping system. In addition to the ultra-pure materials, the company uses a three-step cleaning process, which includes a proprietary pre-assembly clean room treatment; a post-assembly hot and cold 8-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, according to the manufacturer. The Series PRH-U also 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-inch, 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.
