Plast-O-Matic PRH-U valveNew pressure reducing valve uses thermoplastic materials selected specifically for semiconductor, pharmaceutical and other industries requiring ultra-high purity. Series PRH-U 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, the company uses a three-step cleaning process. This 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. 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.
