DUPLOMATIC泄压阀MRQA系列介绍
MRQA 是一种用于底板安装的自动卸荷阀。该阀专用于带有蓄能器的回路，以在蓄能器达到预期压力水平时优化泵的能耗。当达到通过螺杆调节的压力值时，MRQA 阀的作用是将所有泵流量转向油箱，直到工作管路中的压力下降到设定压力的百分比（63% 或 75%，取决于版本） . 然后，通过止回阀恢复泵向回路的流量，直到再次达到设定压力。
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.
