RQRM3-P, RQRM5-P, RQRM7-P, RQA5M-P and RQA7M-P are unloading valves with solenoid actuated venting, for subplate mounting. These valves are specific for circuits with accumulator, to optimize the energy consumption of the pump. They act deviating all the pump flow to the tank when the pressure value adjusted by the screw is reached, until the pressure in the working line B drops to a percentage (63% or 75%, depending by the version) of the set pressure or when the solenoid valve is switched-off. Then, the pump flow to the circuit is restored by means of the check valve until set pressure is reached or until the solenoid valve is switched-off again. RQAM5-P and RQAM7-P are already equipped with the check valve. Instead, RQRM3-P, RQRM5-P and RQRM7-P have a X port to pilot a remote check valve. The valve is available with DC or AC solenoids. Three pressure control ranges up to 280 bar are available, adjustable by a hexagonal head screw. Upon request they can be equipped with a SICBLOC adjustment knob.
