REXROTH OIL CONTROL閥VRFC3-VS系列介紹
從E到R建立了恒定的壓力補償流量，而最小壓力差約為。兩個端口之間存在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)輸出時，將被旁路到T。輸出流量可以從關(guān)閉到閥的標(biāo)稱最大額定值變化。閥模塊包括一個小的先導(dǎo)溢流閥芯，該閥芯可感測調(diào)節(jié)流量的壓力，并在達到最大允許壓力時將其導(dǎo)流至油箱。從R到E的逆流受節(jié)流閥的選定開度限制，并且沒有壓力補償。不允許從T到E或從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 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.
