According to the type of power supply, AC and DC solenoid valves are selected respectively. Generally speaking, AC power supply is easy to access. Voltage specifications as far as possible to choose AC220V, DC24V. The voltage fluctuation of the power supply is usually +10% and -15% AC, and ± % 10 or so DC is allowed. If the voltage is out of tolerance, it is necessary to take voltage stabilization measures or put forward special ordering requirements. The rated current and power consumption should be selected according to the power supply capacity. Attention should be paid to the higher VA value when AC starting, and the indirect guide solenoid valve should be preferred when the capacity is insufficient.
