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。
Parker派克VB*L系列直動(dòng)式比例溢流閥可以對(duì)壓力從zui小至額定壓力進(jìn)行連續(xù)地調(diào)節(jié)。典型的應(yīng)用在：只需要少量油流的液壓調(diào)節(jié)裝置（例如：*的調(diào)整），或者作為變量泵的液壓調(diào)節(jié)機(jī)構(gòu)的先導(dǎo)閥。閥的電氣控制采用插塞式放大器VS110或數(shù)字式放大器VRD350或VRD355，或者PCD模塊。同樣也可以在閉環(huán)壓力調(diào)節(jié)回路中使用。
