BACCARA GEM-SOL GEM-B-31 230V 50HZ 8W电磁阀分为二通式，三通式，230V电压接口1/4~1/2  常闭及常开；当通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，阀门打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差，流体压力推动关闭件向下移动，关闭阀门。 先导式电磁阀为有压差启动，管道内必须有0.3bar启动压力。

BACCARA GEM-SOL GEM-B-31 230V 50HZ 8W solenoid valve is divided into two types, three types, 230V voltage interface 1/4 ~ 1/2 normally closed and normally open; when energized, the electromagnetic force opens the pilot hole The pressure in the upper chamber drops rapidly, forming a high and low pressure difference around the closing member. The fluid pressure pushes the closing member upward and the valve opens. When power is turned off, the spring force closes the pilot hole and the inlet pressure passes through the bypass hole The chamber forms a low, high, and high pressure differential around the valve closing member. The fluid pressure pushes the closing member downward to close the valve. The pilot solenoid valve is activated with a pressure difference, and there must be a starting pressure of 0.3 bar in the pipeline.
