Description

The MRQA is an automatic unloading valve for subplate mounting. This valve is specific for circuits with accumulator, to optimize the energy consumption of the pump when the accumulator has reached the expected pressure level. The MRQA valve acts deviating all the pump flow to the tank when the pressure value adjusted by 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. Then, the pump flow to the circuit is restored by means of the check valve until set pressure is reached again. A version for remote check valve (to be ordered separately) is available. The absence of the accumulator, an incorrect pre-charge value or the incorrect calibration of the pressure value on the valve cause valve to switch continuously creating sudden pressure surges in the circuit.
