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.

Markets:
• Industrial

• Gauge port
• RDM2 – NG06 (CETOP 03), RDM3 – NG10 (CETOP 05)

Applications:
• Suitable for general hydraulic applications

Function:
Code PT: pressure is relieved from P to T at the adjusted value
Code TT: pressure pre-loading in T
