黏度:≤ 21mm2/s
閥體材質:不銹鋼
密封材質:NBR(標準),FKM、EPDM(可選)
標準電壓:AC220V(50/60Hz);DC24V(0Hz)
電壓變化:±10%
防護等級:IP65
安裝:好使線圈朝上
工作原理:
通電時,電磁力把先導孔打開,上腔室壓力迅速下降,在關閉件周圍形成上低下高的壓差,流體壓力推動關閉件向上移動,閥門打開;
斷電時,彈簧力把先導孔關閉,入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差,流體壓力推動關閉件向下移動,關閉閥門。 動作時間很短頻率較高時一般選用直動式,大口徑選用先導式。
流體壓力范圍上限較高,可任意安裝(需定制)但必須滿足流體壓差條件。

How it works:
Energized, the electromagnetic force open the pilot hole, the upper chamber pressure decreased rapidly formed around the closed lower on the high pressure, the fluid pressure to promote off pieces to move up, the valve opens; energized, the spring force of the pilot hole closed , the inlet pressure chamber through the bypass hole quickly formed around the closing valve under high pressure low on fluid pressure to promote off pieces moving down, close the valve. Action time is very short at higher frequencies generally used in direct-acting, large caliber use Pilot.
Features:
Fluid pressure range limit is higher, can be any installation (to be customized) but must meet the conditions of fluid pressure.
