Valves & Actuation

Pressure ratings shown above are the maximum allowable inlet pressure for the solenoid followed by the maximum allowable back pressure @ 73°F.

Series RVDM In-Line Pressure Relief Valves feature a primary rolling diaphragm and 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.  Series RVDM valves are supplied with adjustment screws so that the user can make his own setting according to pressure requirements. Pressure settings can also be made at the factory to customer’s requirements. RVDM valves can be set from 5 to 100 psi (5 to 120 psi for 1/2" size) by simply turning the adjusting bolt.
