What is the current of solenoid valve coil? During the daily use of the solenoid valve, people might usually encounter burning of the solenoid valve coil. Is it related to the solenoid valve coil current? You can find the answer in the following part.
The solenoid valve coil current generally ranges from 700mA to 800mA, while the solenoid valve winding resistance is 10Ω. In the alternating current circuit, the solenoid valve coil is equipped with not only resistance but also inductive reactance. On the capacitance, there is also capacitive reactance. The inductive reactance of the coil with the iron core is usually large.
For example, an inductive reactance has a 300Ω solenoid valve coil, and its total impendence is denoted by Z on the electrician book. Z can be given by the root operation of the inductive reactance square plus the resistance square, or Z =300.17Ω. Under the voltage of 220V, the current is I=220/300.17=0.733A=733mA.
This is a basic method to work out the coil current of solenoid valve. Then, what is the relationship among the solenoid valve coil current, power, resistance, and frequency (Hz). In fact, the AC solenoid valve power is actually not good, which also involves the waveform, valid value, peak value frequency, etc. Therefore, it is usually converted into the DC for the same computing.
Those interested in solenoid valve coil current have mostly explored causes of solenoid valve coil burning. Is the solenoid valve coil current attributable to the solenoid valve coil burning? In fact, there are many causes which might result into solenoid valve coil burning.

- Coil quality problems
- Shut-off overvoltage breakdown
- Too high voltage of power supply
- Repeated impulse, overcurrent or overheating of frequent switching
- Unstable installation and excessive mechanical shock, whose frequent connection and turnoff will cause the overcurrent or overheating.
