Parker派克RE*T(升級(jí)為RE*S)系列比例溢流閥，是由一個(gè)比例電磁鐵操縱的帶集成的電子控制元件的先導(dǎo)級(jí)和一個(gè)DIN-標(biāo)準(zhǔn)的NG25的插裝閥作主級(jí)所組成的。電源電壓以及給定值信號(hào)（電流或電壓值）可以通過(guò)一個(gè)七針插頭進(jìn)行傳輸。輸入的指令可在0至10V或0至20mA間，參見(jiàn)訂貨號(hào)。壓力增大和壓力降低的斜坡時(shí)間可以在兩個(gè)電位計(jì)上互不干涉地進(jìn)行調(diào)節(jié)。當(dāng)不改變?nèi)坑杏玫男盘?hào)范圍時(shí)，zui大和zui小電位可以確定液壓系統(tǒng)的壓力范圍。對(duì)于不同的壓力等級(jí)在先導(dǎo)閥上使用相應(yīng)的調(diào)節(jié)噴嘴。

   溢流閥是一種液壓壓力控制閥，在液壓設(shè)備中主要起定壓溢流作用，穩(wěn)壓，系統(tǒng)卸荷和安全保護(hù)作用。

    定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí)，會(huì)使流量需求減小。此時(shí)溢流閥開(kāi)啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動(dòng)開(kāi)啟）。

    穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓，運(yùn)動(dòng)部件平穩(wěn)性增加。

    系統(tǒng)卸荷作用：在溢流閥的遙控口串接溢小流量的電磁閥，當(dāng)電磁鐵通電時(shí)，溢流閥的遙控口通油箱，此時(shí)液壓泵卸荷。溢流閥此時(shí)作為卸荷閥使用。

    安全保護(hù)作用：系統(tǒng)正常工作時(shí)，閥門(mén)關(guān)閉。只有負(fù)載超過(guò)規(guī)定的極限（系統(tǒng)壓力超過(guò)調(diào)定壓力）時(shí)開(kāi)啟溢流，進(jìn)行過(guò)載保護(hù)，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)zui高工作壓力高10%～20%）。

    實(shí)際應(yīng)用中一般有：作卸荷閥用，作遠(yuǎn)程調(diào)壓閥，作高低壓多級(jí)控制閥，作順序閥，用于產(chǎn)生背壓（串在回油路上）。

    溢流閥一般有兩種結(jié)構(gòu)：1、直動(dòng)型溢流閥 。2、先導(dǎo)式溢流閥。

    對(duì)溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動(dòng)作靈敏，過(guò)載能力大，噪聲小。
