Plast-O-Matic Valves has introduced the series UPRS pressure regulator said to offer superior purity and performance in a full shutoff design. The regulator is available with or without isolated pressure gauge and has an all-thermoplastic fluoropolymer construction.
Components are treated with proprietary boil/acid/scavenge cleaning for minimal particle shedding, the company says.
The downstream pressure reducing valve features full shutoff design —pressure will not equalize across the regulator in a no-flow condition, it adds.
Kynar 740 body and Kalrez FFKM ultrapure grade perfluoroelastomer specification is said to provide the lowest metal ion contamination performance in semiconductor and other high purity applications.
BCF spigots are standard and flare, sanitary and other connection types available. Sizes range from 25 to 63 mm and the set pressure ranges from 5 to 100 psi.
The series UPRS complements the company’s series UPR non shutoff design to provide the purity in process control for deionized water and other critical applications.
