DF(ZCS)-15二位二通水用电磁阀是一种广泛应用于工业自动化控制的流体控制元件。该电磁阀采用先导膜片式结构，具有良好的密封性能和较高的可靠性。它适用于以水或其他液体为工作介质的管路系统，能够实现自动化控制或远程控制，广泛应用于楼宇自控、暖通空调、水厂、环保水处理、石油化工等多个领域。

该电磁阀的工作原理是通过电磁力控制副阀和主阀的开闭。当线圈通电时，电磁力将活动铁芯吸起，副阀打开，主阀腔内的介质外泄，主阀膜片上下产生压力差，膜片被迅速托起，主阀口开启，实现通路。断电时，电磁力消失，活动铁芯复位，副阀关闭，主阀膜片压向阀座，阀门关闭。

DF(ZCS)-15电磁阀的阀体材质为铸铁，膜片密封材料可选用丁腈橡胶（NBR）或氟橡胶（Teflon），能够适应-5℃至80℃的介质温度。其工作形式包括常闭式和常开式，用户可根据实际需求选择。此外，该电磁阀对介质的清洁度要求较低，但为确保性能，建议在阀前安装过滤器。

The DF(ZCS)-15 two-way, two-position water solenoid valve is a widely used fluid control component in industrial automation. This solenoid valve features a pilot diaphragm structure, which ensures good sealing performance and high reliability. It is designed for use in pipeline systems with water or other liquids as the working medium and can achieve automated or remote control. It is widely applied in building automation, HVAC, water plants, environmental water treatment, petrochemical, and many other fields.

The working principle of this solenoid valve is based on electromagnetic force to control the opening and closing of the pilot valve and the main valve. When the coil is energized, the electromagnetic force lifts the movable iron core, opens the pilot valve, and allows the medium in the main valve chamber to be discharged. This creates a pressure difference between the upper and lower parts of the main valve diaphragm, which quickly lifts the diaphragm and opens the main valve port to establish flow. When the coil is de-energized, the electromagnetic force disappears, the movable iron core returns to its original position, the pilot valve closes, and the main valve diaphragm presses against the valve seat to close the valve.

The DF(ZCS)-15 solenoid valve has a cast iron valve body and offers diaphragm sealing materials such as NBR or Teflon, which can adapt to medium temperatures ranging from -5℃ to 80℃. It is available in normally closed and normally open types, allowing users to choose according to their specific needs. Additionally, this solenoid valve has low requirements for medium cleanliness, but it is recommended to install a filter before the valve to ensure performance.
