Introduction of the advantages of using the solenoid valve

As an actuator of automatic instrument, solenoid valve has increased sharply in recent years. The main advantages of the use of the solenoid valve are as follows:
(1) leakage is blocked, internal leakage is easy to control, and use is safe.
Internal and external leakage is a factor that endangers safety. Other automatic control valves usually extend the stem and control the rotation or movement of the spool by electric, pneumatic and hydraulic actuators. It is necessary to solve the problem of leakage and leakage of the dynamic seal of the valve stem in the long run. Only the electromagnetic valve is used by the electromagnetic force to complete the iron core sealed in the magnetic insulating sleeve, and there is no dynamic seal, so the leakage is easy to plug. Electric valve torque control is not easy, easy to produce internal leakage, or even break the stem head; the structure of the solenoid valve is easy to control leakage, until it drops to zero. Therefore, the solenoid valve is particularly safe to use, especially for corrosive, toxic or high and low temperature media.
(2) action express, small power, light shape.
Solenoid valve response time can be short to several milliseconds, even the pilot type solenoid valve can also be controlled within tens of milliseconds. Because of self loop, the reaction is more sensitive than other automatic control valves. The properly designed solenoid valve coil has low power consumption and is an energy-saving product. It can also trigger the action automatically, keep the valve position automatically, and do not consume electricity at all. The size of the solenoid valve is small, which saves space and is light and beautiful.
(3) the system is simple and the computer is cheap.
The solenoid valve itself is simple in structure and low in price. It is easier to install and maintain than other types of actuators such as control valves. What's more, the automatic control system is much simpler and the price is much lower. Because solenoid valve is switch signal control, it is very convenient to connect with industrial control computer. In today's era of computer popularization and price decline, the advantages of solenoid valves are more obvious.
