Plast-O-Matic Valves, Inc. offers the Series PRA valve, a pneumatically-controlled pressure regulator that uses compressed air and two rolling diaphragms to control liquid pressure with greater accuracy than spring-loaded regulators. Also known as a pressure-reducing valve, it maintains a constant downstream pressure from five to 125 psi over varying flow rates. The unit is available in a number of rugged thermoplastics, including Grade 1 Type 1 PVC, natural polypropylene and Kynar® PVDF with FKM or EPDMelastomers. Pipe sizes range from one-quarter through three email@example.com
