Electromagnetic valve coil suitable for Wode excavator

Dampness of the coil will lead to insulation degradation, magnetic leakage, and even cause excessive current in the coil to burn. When it is used at ordinary times, it is necessary to pay attention to waterproof and moistureproof work to prevent water from entering the valve body.

If the voltage of the power supply is higher than the rated voltage of the coil, the main magnetic flux will increase, and the current in the coil will also increase, and the loss of the core will lead to the increase of the temperature of the core and burn out the coil.
