The Difference between Electric Valve and Solenoid Valve

It is quite difficult to point out the differences between electric and solenoid valves. However, the distinction is important when you are trying to put it into specific applications. Both the valve systems have their own set of advantages and disadvantages and are customarily used in all types of applications. These range from consumer products like laptops, industrial products like cranes, medical products like ECG machines, to even military applications like fighter jets.

Differences between electric and solenoid valves

1. Operation

Electric valves are driven by electric motors to produce the valve action. They come in two basic models – electric regulating valves and motorized shut-off valves. Shut off valves are further of two types – fully open and fully closed. Control valves are generally installed over electric valves via a closed-loop regulation to get increased stability.

Solenoid valves on the other hand are operated electromagnetically in order to overcome spring pressure and drive the spool action of the rotating coil. The solenoid valve works more or less like the light switch, but for a different application.

2. Switching process

Electric valves are driven through motors and depend on analog adjustments. The on-off action in these valves can take some time for completion.

Solenoid coils on the other hand have a shorter operation time driven only through coils.

3. Application process

Electric valves are used to both regulate and switch systems such as fan coil ends.

Solenoid is more suitable for specific requirements such as leaks and also while dealing with special fluids.

4. Practical uses

Electric valves are used to simulate either liquid, gaseous or wind systems piping through AI controls. They can also be used in combinations of two or more valves to operate large valve systems.

Solenoid valves are however specifically used in liquid or gas control by using an electric current through the solenoid.
