品牌:RETZ瑞茨/我們一直致力于流體控制領域的持續創新,始于2005……進口先導式電磁閥比較適合大口徑場合,高壓力工況下使用,需要注意的是,流通的介質-定要大于0.03Mpa的壓力才能正確使用本產品廣泛應用于蒸汽系統,高壓系統,低溫系統,工業石油供用系統,灌裝系統,液化氣系統,供熱系統,儲灌設備,電廠設備,石化設備,氣動設備,管道自控等自動化裝置retz The pilot operated solenoid valve is more suitable for large diameter occasions and high pressure conditions. It should be noted that the circulating medium must be greater than 0.03Mpa to use correctly. This product is widely used in steam systems, high-pressure systems, low-temperature systems, industrial oil supply systems, filling systems, liquefied gas systems, heating system, storage and irrigation equipment, power plant equipment, petrochemical equipment, pneumatic equipment, pipeline automation and other automation devices
注解-
1.流體中若含有雜質,電磁閥進端必須安裝過濾閥(精度40—200目),
2.電磁閥安裝方位無限制。(S-水平安裝、C-垂直安裝)
3.無粘稠,無凝固及結晶現象。
進口先導式電磁閥控制原理--
常閉:
當線圈通電時,先導閥芯吸合,先導孔打開,閥上腔卸壓,活塞靠下腔介質壓力推動,電磁閥打開。當線圈斷電時,先導閥芯靠彈簧復位,先導孔關閉,閥上腔由活塞節流孔增壓和復位彈簧的推力,電磁閥關閉。
