Series RVDM in-line pressure relief valves feature a primary rolling diaphragm and a secondary flat diaphragm which incorporates the Plast-O-Matic patented Fail-Dry design for added protection. If the rolling diaphragm should fail, liquid will weep through the vent port which is located between the two diaphragms. Leakage indicates maintenance is required and can be conveniently scheduled eliminating an emergency shutdown. The second diaphragm protects the control spring from the liquid. Additionally, the rolling diaphragm eliminates crystallization problems. PP and PVDF available.
