BACCARA GEM-SOL GEM-B-31 230V 50HZ 8W電磁閥分為二通式，三通式，230V電壓接口1/4~1/2  常閉及常開；當通電時，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。 先導式電磁閥為有壓差啟動，管道內必須有0.3bar啟動壓力。

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.
