原理：通電時(shí)，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān) 閉件周圍形成上低下高的壓差，流體壓力推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。
GSR先導(dǎo)閥是一種先導(dǎo)閥與主閥兩者間相互的閥體當(dāng)電磁閥線圈通電，動(dòng)鐵芯與靜鐵芯吸合使導(dǎo)閥孔開放，閥芯背腔的壓力通過導(dǎo)閥孔流向出口，此時(shí)閥芯背腔的壓力低于進(jìn)口壓力，利用壓差使閥芯脫離主閥口，介質(zhì)從進(jìn)口流向出口。當(dāng)線圈斷電，動(dòng)鐵芯與靜鐵芯脫離，關(guān)閉了導(dǎo)閥孔，閥芯背腔壓力受進(jìn)口壓力的補(bǔ)充逐漸趨于和進(jìn)口平衡，閥芯因彈簧力作用下把閥門緊密關(guān)閉。 特點(diǎn)：功率消耗低、通徑較大，而結(jié)構(gòu)簡單、安裝方向任意，但只能用于電磁閥兩端有一定壓差的場合，主要應(yīng)用在汽車，電廠，鋼廠，船廠等行業(yè)
原裝正品德國GSR氣動(dòng)閥現(xiàn)貨
1）GSR與固定液阻組成先導(dǎo)控制液橋，根據(jù)輸入信號(hào)對(duì)主閥或次級(jí)閥或變量杠進(jìn)行控制；
2）GSR首級(jí)先導(dǎo)閥的流量一般都只在1升/分左右，zui大3升/分。二級(jí)先導(dǎo)閥流量就要根據(jù)實(shí)際需要決定。
3）GSR輸入信號(hào)都比較小；
4）GSR可以接受多種輸入方式，如手動(dòng)、電動(dòng)、液動(dòng)、氣動(dòng)、機(jī)械凸輪、電比例等；
5）GSR在變量泵控制等情況，多種先導(dǎo)閥形成模塊化結(jié)構(gòu)，多種功能取舍方便；
6）GSR先導(dǎo)閥本身往往就是一種小規(guī)格控制閥，多為壓力控制閥。
