Parker Series RDM(AP) Direct Operated Pressure Relief Valve

Parker’s pressure relief valves series RDM in sandwich design enable an easy configuration of stack systems. The direct operated piston type valves provide low hysteresis and thus a precise pressure control. Series RDM can be used as P-T relief or as T-T controlled counter balance valve. The valve body is equipped with a pressure gauge port.
