美國沃克(WORK)運用直動和先導式相結合的原理,當入口與出口沒有壓差時,通電后,電磁力直接把先導小閥和主閥關閉件依次向上提起,閥門打開。當入口與出口達到啟動壓差時,通電后,電磁力先導小閥,主閥下腔壓力上升,上腔壓力下降,從而利用壓差把主閥向上推開;斷電時,先導閥利用彈簧力或介質壓力推動關閉件,向下移動,使閥門關閉。
特點: 在零壓差或真空、高壓時亦能可*動作,但功率較大,要求必須水平安裝。
控制方式:常開常閉
可帶手動操作
公稱通徑:DN1-80mm(DN100以上訂貨時咨詢)

閥體材質:不銹鋼,SS304,WCB,特制SS316
密封材料:NBR,FKM,PTFE,紫銅等
工作溫度:-30℃-60℃(防爆型-20℃-40℃)
適用介質:氣體,液體
流體粘度:≤22mm2/S(其他可定制)
防護等級:普通型IP54,IP65防爆型IP65
電氣參數:
