三、进口零压差电磁阀性能特点：

1、有活塞式结构和膜片式结构；

2、零压启动、低压结合，性能稳定；

3、塑封线圈，提高阀的可靠性并能防水、防潮，不易烧毁，线圈不易烧毁；

4、线圈启动阀芯同时拉动活塞，在零压时都能正常工作；

5、长时间停止动作重新启动，动作同样灵敏，使用寿命长。

3、 Performance characteristics of imported zero differential pressure solenoid valve:

1. There are piston structure and diaphragm structure;

2. Zero voltage start, low voltage combination, stable performance;

3. The plastic sealing coil can improve the reliability of the valve, prevent water and moisture, and is not easy to burn;

4. The coil starts the valve core and pulls the piston at the same time, which can work normally at zero pressure;

5. Long time stop action restart, action is also sensitive, long service life.
