DUPLOMATIC泄壓閥MRQA系列介紹
MRQA 是一種用于底板安裝的自動卸荷閥。該閥專用于帶有蓄能器的回路，以在蓄能器達(dá)到預(yù)期壓力水平時(shí)優(yōu)化泵的能耗。當(dāng)達(dá)到通過螺桿調(diào)節(jié)的壓力值時(shí)，MRQA 閥的作用是將所有泵流量轉(zhuǎn)向油箱，直到工作管路中的壓力下降到設(shè)定壓力的百分比（63% 或 75%，取決于版本） . 然后，通過止回閥恢復(fù)泵向回路的流量，直到再次達(dá)到設(shè)定壓力。
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.
