REXROTH OIL CONTROL阀VRFC3-VS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处的调节输出时，将被旁路到T。输出流量可以从关闭到阀的标称最大额定值变化。阀模块包括一个小的先导溢流阀芯，该阀芯可感测调节流量的压力，并在达到最大允许压力时将其导流至油箱。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E或从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 bypassed to T. Output flow can be varied from closed to the nominal maximum rating for the valve. The valve module includes a small pilot relief cartridge which senses the pressure of the Regulated flow and diverts it to tank if the maximum allowed pressure is reached. Reverse flow from R to E is limited by the selected opening of the restrictor and is not pressure compensated. Flow from T to E or from T to R is not permitted.
