The 12v solenoid valve for water is divided into coil and body. The coil is connected to the wires of the outside world. The coil is wrapped in insulating plastic. The problem is that if the solenoid valve is put into the water as a whole, the water molecules will inevitably enter the coil insulator, thus there is the possibility of leakage. Unless the insulator completely seals the wire and coil as a whole.
