REXROTH OIL CONTROL閥VRFC3-VS-BPE系列介紹
從E到R建立了恒定的壓力補(bǔ)償流量，而最小壓力差約為。兩個(gè)端口之間存在5 bar（70 psi）的壓力。供應(yīng)給E的輸入流量超過R處的調(diào)節(jié)輸出，將被旁路到T。調(diào)節(jié)流量可以從關(guān)閉到閥的標(biāo)稱最大額定值變化，并且其壓力由溢流閥控制，該溢流閥將排放到Tank上。如果達(dá)到最大壓力，則輸出流量。斷電時(shí)，常開螺線管盒會(huì)將所有入口流量旁路到油箱。從R到E的逆流受節(jié)流閥的選定開度限制，并且沒有壓力補(bǔ)償。不允許從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.
