RM Series Sandwich Valves

Pilot operated pressure relief valves series RM ensure a long service life due to valve bodies manufactured from steel. The sandwich design enables an easy configuration of stack systems. Depending on type, pressure limiting can be achieved in ports P, A or B with unloading to port T. RM valves may only be mounted in the defined mounting position.

    Mechanical

    Minimum Pressure 10 bar (150 psi) with rated flow, 150 SSU oil, and fluid temperature of 38°C (100°F) Change in flow, temperature or fluid (SSU) rating will affect valve minimum pressure.
    Maximum Pressure 350 bar (5,000 psi) -
    Minimum Flow 3.78 LPM (1 GPM) -
    Maximum Flow RM2: 53 LPM (14 GPM) -
    RM3: 76 LPM (20 GPM) -
    RM6: 341 LPM (90 GPM) -
    Pressure Range Code 07: 10 to 70 bar (150 - 1,000 psi) -
    Code 17: 10 to 175 bar (150 - 2,500 psi) -
    Code 25: 10 to 250 bar (150 - 3,500 psi) -
    Code 35: 10 to 350 bar (150 - 5,000 psi) -
    Filtration ISO 4406 (1999); 18/16/13 (meet NAS 1638:7) -
    Venting Connecting the vent port to tank allows the relief valve to divert flow at minimum pressure. No available on Model RM2.
    Remote Control Remote control valve connected to the vent port can be used to control the pressure. Set main valve pressure 10 bar (150 psi) higher than remote pilot.
