Hydraulic solenoid valves work on the principle of electromagnetism and control the flow of fluids like liquid or gas. There’s a switch which energizes the solenoid coil and causes the valve to open or close. There may be several rubber seals to help control the procedure. When the valve is either open or closed, it can be kept in the same position with the help of a spring. In addition there’s a diaphragm which permits the liquid or gas to flow from one side to another. The differential pressure causes the valve to open and shut.

Seeing as there are so many parts in a solenoid valve, you may be sure that with time, many of them will be worn out and must be replaced. Often, there will be a minor problem which can often be fixed in time. You really should know all the parts and their functioning to be in a position to discover the problem in them. After you know the difficulty, it’s going to be straightforward to remedy.

There’s a hole in the diaphragm of the hydraulic solenoid valve. This could get clogged with dust and pollutants with time. But such a little problem can hamper the working of the solenoid valve and you cannot use it. This problem is so easy to repair as you can just open the valve and clean the diaphragm and the area where it is located. There might be a few bolts you have got to unscrew to split the parts and do the job.

There is a awfully fast method to learn if the solenoid valve is working properly. When you switch the valve on and off, there should be a faint click sound. This is because of the diaphragm lifting and coming down. If you don’t hear the sound, it may mean that electrical power is not reaching the diaphragm. This may be due to defective wiring. The solenoid might be damaged too , which implies you should replace it.

There could be an issue with the plunger too. It might stick due to dirt causing the machine to stop working. Cleaning it or replacing it’ll solve the problem. Often, there could be a difficulty in the fluid supply. You can have it filtered before reaching the diaphragm.
