2W水用黃銅、不銹鋼電磁閥里有密閉的腔，在不同位置開有通孔，每個孔都通向不同的油管，腔中間是閥，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來檔住或漏出不同的排油的孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞竿帶動機械裝置動。這樣通過控制電磁鐵的電流就控制了機械運動。2W water brass, stainless steel solenoid valve from the principle divided into three categories (ie: direct acting, step by step direct-acting, pilot), but the difference with the principles from the different valve configurations and materials on again is divided into six branches categories (direct-acting diaphragm structure, step by step re-sheet structure, the pilot membrane structure, direct-acting piston structure, step by step direct-acting piston structure, the pilot piston structure), is divided into two large ones in accordance with gas 2-way, two 3-way, two 4-way, 2 through 5.
Into a single electronically controlled solenoid valve and double solenoid, referring to the number of electromagnetic coils, single coil called a single solenoid, double coil is called double solenoid, two 2-way, two 3-way general When a single solenoid (single coil).
