(1) The system is simple, easy to connect to the computer, and the price is low. The solenoid valve itself has simple structure and low price. It is easier to install and maintain than other kinds of actuators such as regulating valve. More significantly, the automatic control system is much simpler and the price is much lower. Because the solenoid valve is controlled by switching signal, it is very convenient to connect with industrial control computer. In today's era of popularization of computers and sharp decline in prices, the advantages of solenoid valves are more obvious.

(2) The external leakage is blocked, the internal leakage is easy to control, and the use is safe. Internal and external leakage is an element endangering safety. Other automatic control valves usually extend the valve stem, and the rotation or movement of the valve core is controlled by electric, pneumatic and hydraulic actuators. This should solve the problem of leakage of long-term action valve stem dynamic seal; Only the solenoid valve is completed by using electromagnetic force on the iron core sealed in the magnetic isolation sleeve. There is no dynamic seal, so the external leakage is easy to be blocked. The torque control of electric valve is not easy, which is easy to produce internal leakage and even break the head of valve rod; The structure of the solenoid valve is easy to control the internal leakage until it is reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially for corrosive, toxic or high and low temperature media.

(3) The action is express, the power is small, and the shape is light. The response time of the solenoid valve can be as short as a few milliseconds, and even the pilot solenoid valve can be controlled within tens of milliseconds. Because of its own circuit, it is more sensitive than other automatic control valves. The properly designed solenoid valve coil has low power consumption and is an energy-saving product; In addition, it can only trigger the action and automatically maintain the valve position without power consumption at ordinary times. The solenoid valve has small overall size, which not only saves space, but also is light and beautiful.

(4) Various models and wide applications. Although the solenoid valve has inherent shortcomings, its advantages are still very prominent, so it is designed into a variety of products to meet different needs and has a wide range of uses. The progress of solenoid valve technology is also centered on how to overcome congenital deficiencies and give better play to its inherent advantages.
