A solenoid valve, also known as an electrically-operated valve, is a valve that uses electromagnetic force to operate. When an electrical current is passed through the solenoid coil, a magnetic field is generated which causes a ferrous metal rod to move. This is the basic process that opens the valve and it works either directly or indirectly on the air.

Solenoid valves can be normally open or normally closed:

Normally Open (N/O), the valve remains open when the solenoid is not charged.

Normally Closed (N/C), the valve remains closed when the solenoid is not charged.

Power condition

1) According to the type of power supply, select AC and DC solenoid valves respectively. Generally speaking, AC power is easy to access;

2) AC220V.DC24V should be preferred for voltage specifications;

3) The power supply voltage fluctuation is usually +%10%.-15% for AC and ±%10 for DC. If it is out of tolerance, voltage stabilization measures must be taken;

4) The rated current and power consumption should be selected according to the power supply capacity. It should be noted that the VA value is higher during AC starting, and the indirect pilot solenoid valve should be preferred when the capacity is insufficient.
