Plast-O-Matic Pressure Relief Valves for Commercial RO Systems
Pressure Relief Valves to protect RO systems and equipment from damage due to high pressure.

Series RVDM in-line pressure relief valve features a primary rolling diaphragm and a secondary flat diaphragm which incorporates the Plast-O-Matic patented Fail-Dry design for added protection. For use as back pressure valve, straight relief, by-pass relief or back pressure regulator.

Relief setting is infinitely adjustable from 5 psi to 100 psi. 1/2" size to 120 psi. Maximum inlet pressure is 150 psi. Not recommended for applications with vacuum or backpressure on the outlet
