The solenoid valves are an essential part of the piping system or network. The proportioning solenoid valve control circuit includes a coil, a plunger, and a spring. There can be a problem with the relative motion of the coil and the plunger during the work. The other problem may be the compatibility of the coil and the electric supply, as it slows down the speed of the solenoid valves.
You may experience a slow working process on the solenoid flow control valve due to rust or dust particles. It may be that the dust particles are tangled in the solenoid flow valve and hinder the flow of liquids or gases.
In this article, we are discussing the various methods of testing solenoid air flow control valves.
Test with the Multimeter:
The quick way to test the proportional valve controller circuit is simple and described as follows: Just see that there are two wires that are connected above the valves. Connect the multimeter with these two wires; if the multimeter is showing a normal reading, it means the valves are working properly.
If you want to confirm that the solenoid valve is working properly, take a lamp or electric bulb and connect it to the wires of the multimeter. If the current is flowing well through the valves, then the electric bulb will light up. It means the proportioning solenoid valve control circuit is working properly. On the other hand, if the electric bulb is not lighting up, then replace the solenoid valves.
The Manual Testing of the Solenoid Valves:
Locate the valves in the piping system, The electric proportional control valve control circuit consists of copper wires, an iron plunger, and a spring. Just examine the coil and the iron plunger; you need to check that the coil is fresh and not melted down. Then examine the whole solenoid valve and remove any sort of dust particles from the valve. Check the spring to see if it is properly placed, and move the coil.
The working principle of the solenoid valves is simple: there are two forces acting at the same time. The electromagnetic force and the spring force are in the resting position, and the solenoid valve remains in the closing position. Check the relative motion of the spring and the iron plunger in the solenoid valves.
A Homemade Test:
If you have no multimeter available, then use a bulb and battery to check the workings of the solenoid valves. Press the battery around the wires that surround the solenoid valves. Then connect the electric bulb to check if the flow of the current is proper.
When you connect the bulb, it will light up, just as with the multimeter. The homemade test of the proportioning solenoid valve control circuit is simple, and anyone can perform it at home.
The flow control solenoid valve is a sensitive device, and there can be various problems with its working. You can check the working condition of the solenoid valves with the simple test mentioned above. These tests are simple, and anyone can perform them to check the solenoid valve’s functionality.
