Electric valve and solenoid valve the difference between 1. The nature of work: Electric valve drive motor is generally used, more resistant to voltage surge. Solenoid valve is fast opening and quick closing, usually used in low flow and small pressure for large parts of the switching frequency electric valve and vice versa. Electric valve opening can be controlled, the state has opened, closed, half open half closed, you can control the flow of media and pipeline valve to meet this requirement. Solenoid valve flow coefficient is generally small, and the working pressure difference is small. Such as the general circulation of the solenoid valve 25 caliber 15 caliber than the coefficient of the electric valve is much smaller. Solenoid valve is driven by the electromagnetic coil voltage shock more easily damaged. Equivalent to the role of the switch is on and off 2 role. General power to reset the solenoid valve, electric valve to reset this feature requires additional equipment. 2 switches in the form: Electric valve drive motor is generally used, on or off the action will take some time to complete the analog, and can do adjustments. Driven by the solenoid valve coil, only on or off, switch operating time is short. 3 application process: Electric valves are generally used for regulation, but also switch, such as: fan coil end. Solenoid valve is suitable to process some special requirements, such as leakage, fluid medium special and so expensive.

1.工作性质：电动阀的驱动一般是用电机，比较耐电压冲击。电磁阀是快开和快关的，一般用在小流量和小压力，要求开关频率大的地方电动阀反之。电动阀的开度可以控制，状态有开、关、半开半关，可以控制管道中介质的流量而电磁阀达不到这个要求。电磁阀一般流通系数很小，而且工作压力差很小。比如一般２５口径的电磁阀流通系数比１５口径的电动球阀小很多。电磁阀的驱动是通过电磁线圈，比较容易被电压冲击损坏。相当于开关的作用，就是开和关2个作用。　电磁阀一般断电可以复位，电动阀要这样的功能需要加复位装置。 2.开关形式：电动阀的驱动一般是用电机，开或关动作完成需要一定的时间模拟量的，可以做调节。电磁阀通过线圈驱动，只能开或关，开关时动作时间短。 3.适用工艺：电动阀一般用于调节，也有开关量的，比如：风机盘管末端。电磁阀适合一些特殊地工艺要求，比如泄漏、流体介质特殊等，价格较贵。
