本色品質,精雕細做-德國卡爾
原理:它是一種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。
廣泛應用在航天、船舶重工、石油化工、工業爐窯、鍋爐、給排水、采暖空調、消防設備、干燥設備
食品醫療設備、清洗設備、景觀灌溉、噴泉、水廠等管道系統中.
It is widely used in aerospace, shipbuilding Heavy Industry, petrochemical, industrial furnaces, boilers, plumbing, heating and air conditioning, fire-fighting equipment, drying equipment,Food medical equipment, cleaning equipment, landscape irrigation, fountains, water and other piping systems

工作原理 Work
☆常閉型:線圈通電時,主閥芯靠介質壓差力打開;線圈斷電,閥關閉。
☆常開型:線圈通電時,閥關閉;線圈斷電,主閥芯靠介質壓差力打開。
☆ Normally closed type: coil power, the main valve to
open by medium pressure force; coil power, valve closed
☆ Normally open type: coil power, the valve closed; coil power,
pressure forces the main valve opens by media
備注:當出口端壓力大于進口端壓力,介質回反向導通。
可安裝止回閥或訂制帶止回功能的閥。
When the exit pressure is greater than the inlet pressure, medium
Back to pass against the wizard.
Check valve can be installed or ordered withnon-return valve function
