Company has developed a new pressure reducing valve using 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, according to the manufacturer. In addition to the ultra-pure materials, the manufacturer uses a three-step cleaning process, which includes a proprietary pre-assembly clean room treatment; a post-assembly hot and cold eight-hour rinse with de-ionized water; and a final class 100 clean and double-bag procedure. In addition to its ultra-high purity levels, the valve 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- 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.
