A solenoid consists of the coil, the tube, and the armature. As a main part of the solenoids, the solenoid coils have their service life. They are replaceable parts of the hydraulic solenoid valve. You need to change the solenoid coils when they are damaged, broken or worn out.

There is little difference in the types of replacement solenoid coils. The main difference may be manufacturers. You may feel it is sometimes difficult to find an original model. A compatible one is available.
- You need to figure out the right current type and voltage. AC or DC types, various voltages like 12v, 24v, 100v, 110v, 120v, 200v, 220v. Determine the power supply is half done the work.
- Compare the dimensions of the replacement solenoid coils. The hole’s diameter and height should be near the original one. The clearance is the small the better.

- The installation is easy after choosing the right solenoid coils replacement. First, make sure that the wiring has been removed. The valve can still be in the pipeline. Remove cap nut and set aside. Remove o ring and coil. Open replacement coil. Read the instructions. Take out a new coil. Confirm that the new o ring is in place. Put the new coil on the valve with the o ring faces up. Fasten the cap nut securely. Then you’re ready to rewire the connector. Solenoid coils have different connector types. One mostly used connector is DIN 43650. Find your matching connector.
Special attention. Do not energize the solenoid coil before mount it onto the core. Otherwise, the coil can easily be burnt.
