Parker派克RE*W系列直動(dòng)式比例溢流閥允許連續(xù)調(diào)整閥的zui低壓力至額定壓力。通常僅用于需要很小流量的液壓設(shè)備調(diào)節(jié)，或作為調(diào)節(jié)變量泵的先導(dǎo)閥。閥的電比例控制采用PCD00A-400數(shù)字放大板進(jìn)行，并可用于壓力的閉環(huán)控制。 派克RE*W系列直動(dòng)式比例溢流閥的結(jié)構(gòu)：比例溢流閥由錐形閥芯和相應(yīng)的閥芯座及比例電磁鐵組成。來(lái)自放大板的命令信號(hào)可以調(diào)定所需的壓力。比例電磁鐵可把放大板的輸出電流轉(zhuǎn)變?yōu)榱Φ妮敵觯饔迷陂y芯上。壓力范圍與電磁鐵的輸出力相對(duì)應(yīng)。
Parker比例溢流閥的原理：在失電條件下，閥處于卸荷狀態(tài)。其上的zui小壓力取決于通過(guò)閥的流量。當(dāng)比例電磁得電時(shí)，產(chǎn)生電磁力，壓力升高，直到作用在閥芯的電磁力與液壓力平衡。
派克RE*W系列直動(dòng)式比例溢流閥的特性：通過(guò)比例電磁鐵直接驅(qū)動(dòng)。zui小調(diào)節(jié)壓力低。磁滯＜±1.5%，重復(fù)精度＜1%，高響應(yīng)。4級(jí)壓力調(diào)節(jié)范圍，可獲得更好的調(diào)整效果；50、105、210及350bar。數(shù)字放大器PCD00A-400.閥及放大器可配套供貨，以保證*性能。
