Solenoid valve advantages:

(1) External leakage blockage, internal leakage easy control, safe use.

Internal and external leakage is an important factor endangering safety. Other automatic control valves usually extend the stem, and electric, pneumatic, and hydraulic actuators control the rotation or movement of the spool. This must solve the long-term role of stem dynamic seal outside the leakage problem; Only solenoid valve is sealed in the magnetic isolation sleeve of the electromagnetic force on the core to complete, no dynamic seal, easy to plug the leak. Electric valve torque control is not easy, easy to produce internal leakage, even the stem head fracture; The design of the solenoid valve makes it easy to control internal leakage until it drops to zero. Therefore, the use of solenoid valve is particularly safe, especially suitable for corrosive, toxic or high and low temperature media.

(2) active carbon solenoid valve action expression, small strength, light shape.

Solenoid valve response time can be as short as a few milliseconds, and even the pilot solenoid valve can be controlled within tens of milliseconds. Due to its own loop, more sensitive than other automatic control valves. Well-designed solenoid valve coil low power consumption, is an energy-saving product; The valve position can also be automatically maintained by triggering action only, without power consumption. The electromagnetic valve body is small, saving space, light and beautiful.

(3) the direct moving solenoid valve system is simple, can connect the computer, the price is low and moderate.

Solenoid valves are simple in structure, low in price, and easier to install and maintain than other actuators such as regulating valves. What's more, the automatic control system is much simpler and much cheaper. Because the solenoid valve is controlled by the switch signal, it is very convenient to connect with the industrial computer. In today's computer popularity, the price of a significant decline in the era, solenoid valve advantage is more obvious.
