There are several types of voltages for the electronic valve of the spray fuel dispenser

One: The voltage of the electronic valve is AC220V. Two: The voltage of the electronic valve is DC220. Three: The voltage of the electronic valve is AC24V. Four When replacing an old circular machine with a brand-new fuel injector, it is essential to measure the voltage with a multimeter at the fuel injector’s connection port to determine whether it is AC or DC. Generally, the commonly used voltage is AC220V, while imported machines are usually AC24V. After confirming whether the voltage is AC or DC, it is best to contact the manufacturer to inform them of the minimum voltage. That’s fine.
