Precautions for using manual solenoid valves

Manual solenoid valves do not mean that they are manually controlled, they are solenoid valve products with manual operation functions, and they also belong to automated control devices. So what should be noted when using manual solenoid valves?

Manual solenoid valves for general and alarm types.

There are two types of ordinary manual solenoid valves: normally open and normally closed. When using a normally open manual solenoid valve that requires automatic control, the manual handle must be in the open state; When the coil loses power, rotating the manual handle can control the valve switch.

When the normally closed manual solenoid valve needs automatic control, the manual handle must be in the closed state; When the coil loses power, rotating the manual handle can control the valve switch.

When the alarm type manual solenoid valve needs to be opened, unscrew the protective cover (there is a threaded hole in the middle of the protective cover, and screw it onto the linkage rod to use as the handle), and pull the handle firmly to open the valve. When it is necessary to close, the coil is energized for no more than 30 seconds and the valve quickly closes.
