(1) High cost performance
Since the solenoid valve is controlled by a switch signal, it is very convenient to connect with the computer. In today’s era when computers are popular and prices drop sharply, the advantages of solenoid valves are even more obvious. The solenoid valve itself has a simple structure and a relatively low price. It is easier to install and maintain than other types of actuators such as control valves.
(2) Good safety performance
The structure of the solenoid valve is easy to control internal leakage until it drops to zero. The solenoid valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve. There is no dynamic seal, so the external leakage is easy to block. Therefore, the solenoid valve is very safe to use, especially suitable for corrosive, toxic or high and low temperature media.
(3) energy saving
The response time of the solenoid valve can be as short as a few milliseconds, even the pilot solenoid valve can be controlled within tens of milliseconds. Because of its self-contained circuit, it is more sensitive than other automatic control valves. A properly designed solenoid valve coil has low power consumption and is an energy-saving product. It is also possible to automatically maintain the valve position by simply triggering the action without consuming electricity at all. The solenoid valve is small in size, which saves space and is light and beautiful.
(4) The adjustment accuracy is not high and is affected by the flow medium
Solenoid valves usually have only two states on and off. The spool can only be in two extreme positions and cannot be adjusted continuously. There are many new ideas trying to break through, but they are still in the trial stage, so the adjustment accuracy is still subject to certain restrictions.
Solenoid valves have high requirements for the cleanliness of the medium, and the granular medium cannot be used. If it is impurities, it must be filtered out first. In addition, viscous media cannot be applied, and the viscosity range of the media for specific products is relatively narrow.
