REXROTH OIL CONTROL阀VRFC3-VS-BPE系列介绍
从E到R建立了恒定的压力补偿流量，而最小压力差约为。两个端口之间存在5 bar（70 psi）的压力。供应给E的输入流量超过R处的调节输出，将被旁路到T。调节流量可以从关闭到阀的标称最大额定值变化，并且其压力由溢流阀控制，该溢流阀将排放到Tank上。如果达到最大压力，则输出流量。断电时，常开螺线管盒会将所有入口流量旁路到油箱。从R到E的逆流受节流阀的选定开度限制，并且没有压力补偿。不允许从T到R的流量。
A constant pressure compensated flow rate is established from E to R, while a minimum pressure differential of appr. 5 bar (70 psi) exists between the two ports. Input flow supplied to E in excess of the regulated output at R is by-passed to T. Regulated flow can be varied from closed to the nominal maximum rating of the valve and its pressure is controlled by a relief cartridge which will dump to Tank the output flow if the maximum pressure is reached. A normally open solenoid cartridge by-passes all Inlet flow to tank when de-energized. Reverse flow from R to E is limited by the selected opening of the restrictor and is not pressure compensated. Flow from T to R is not permitted.
