Advantages of Solenoid Valves

Mar. 30, 2020

As a kind of actuator of the automation instrument, the solenoid valve has been used rapidly in recent years. The use of solenoid valves has the following advantages:

(1) The external leakage is blocked, and the internal leakage is easy to control and safe to use.

Internal and external leaks are a threat to 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 has to solve the problem of external leakage of the long-term action valve stem dynamic seal; only the solenoid valve is completed by electromagnetic force acting on the iron core sealed in the magnetically shielded sleeve. Electric valve torque control is not easy, it is easy to produce internal leakage, and even break the stem head; the structure of the solenoid valve is easy to control internal leakage until it reaches zero. Therefore, the use of solenoid valves is particularly safe, especially suitable for corrosive, toxic or high and low-temperature media.

(2) Express action, small power, lightweight.

The solenoid valve response time can be as short as a few milliseconds, and even pilot-operated solenoid valves can be controlled within tens of milliseconds. Due to its own circuit, it is more sensitive than other self-control valves. A properly designed solenoid valve coil consumes very low power and is an energy-saving product. It can also automatically trigger the action and maintain the valve position without power consumption. The small size of the solenoid valve saves space and is light and beautiful.

(3) The system is simple, the computer is connected, and the price is low.

The solenoid valve itself has a simple structure and a low price and is easier to install and maintain than other types of actuators such as regulating valves. What is more remarkable is that the automatic control system is much simpler and the price is much lower. Since the solenoid valve is controlled by a switch signal, it is very convenient to connect with an industrial computer. In today's era of popularization of computers and sharply lower prices, the advantages of solenoid valves are even more obvious.
