1 IN Plastomatic PRHM100V-PV PVC PRV

Series PRH offers the highest available performance in a standard, spring-type regulator -- please scroll below to see the competitive test results. Based on the same large area frictionless rolling diaphragm, poppet seat, isolated pressure sensing chamber and pressure balanced shaft of Series PR, this valve uses higher capacity springs and an expanded base to accommodate the increased pressure settings. -Downstream pressure setting is infinitely adjustable from 30 psi to 125 psi. -Maximum inlet pressure is 150 psi. -Available in PVC, Natural Polypro, Kynar PVDF and PTFE; sizes 1/4", 1/2", 3/4", 1", 1-1/2", 2" & 3". -Balanced Geon PVC shaft provides smooth, non-stick operation; assures reliable service for millions of cycles. -Large surface area of the frictionless diaphragm provides exceptional sensitivity. -Double u-cups prevent leakage along the shaft and eliminate the possibility of "creep". -Designed for low maintenance and easy to adjust. -High capacity, heavy-duty design. Corrosion resistant, also excellent for high purity and water applications. The standard connections are female NPT threaded ports. Springs (not wetted) and external fasteners are stainless steel.
