2W水用黄铜、不锈钢电磁阀适用于以水或液体为工作介质，可自动化控制或原虫控制水、油、液体等工作介质管路的通断。2W水用黄铜、不锈钢电磁阀由于本阀采用橡胶密封，故对工作介质的清洁大大减低，具有启闭迅速，可靠性等特点。

上海阔志阀门有限公司水用电磁阀的工作原理如下：水用电磁阀为二次开阀的先导式电磁阀，其结构主要由导阀和主阀组成，主阀采用橡胶密封结构。常位时，活动铁芯封住导阀口，阀腔内压力平衡，主阀口封闭。当线圈通电时，产生电磁力将活动铁芯吸上，主阀腔内的介质自导阀口外泄，以至产生压力差，膜片或阀杯被迅速托起，主阀口开启，阀便呈通路了。当线圈断电，磁场消失，活动铁芯复位，封闭导阀口，导阀和主阀腔内压力平衡后，阀又呈关闭状态。2W water at home and abroad with brass, stainless steel solenoid valve from the principle divided into three categories (ie: direct acting, step by step direct-acting, pilot), but from a different valve structure with the principles and materials on The difference 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), the large ones divided according to gas for the two 2-way, two 3-way, two 4-way, 2 through 5.

2W water brass, stainless steel solenoid valve is divided into single and double electric control electric control, referring to the number of electromagnetic coils, single coil called a single solenoid, double coil is called double solenoid, 2 2 pass, two 3-way general when is single solenoid (single coil).
