Why is the solenoid valve often unable to close or open when it is used?

The reason why the solenoid valve cannot be closed:
①Reverse installation
The solenoid valve cannot be installed in reverse. When installing, pay attention that the arrow on the valve body should be consistent with the flow direction of the pipeline fluid, and the coil should be installed vertically upward and horizontally.
② Card thing
If there are impurity particles in the medium, the valve port will be stuck out, resulting in the failure to close or open the solenoid valve. Disassemble the solenoid valve, clean it, and then install it (the solenoid valve requires a relatively clean medium, if there are tiny impurities in the medium The filter provided by "our company" must be installed in front of the valve (filter screen ≥80 mesh/cm2).)
③Incorrect pressure
Is the pressure standard? Choose a fully direct-acting solenoid valve for 0 pressure and steam.

 

Low Power Consumption Solenoid Valve

 
The reason why the solenoid valve cannot be opened:
①The pressure is not right
Is the pressure standard? Choose a fully direct-acting solenoid valve for 0 pressure and steam
②The voltage is wrong (the voltage is wrong, the power is not enough)
Before installation, check whether the pressure, temperature, and voltage are consistent with the solenoid valve nameplate and actual parameters. The length of the DC (DC) power cord should not be too long, so as to avoid coil power loss and voltage drop affecting normal operation (DC24V should not exceed 30m).
③ Card things
If there are impurities in the medium, the valve port will be stuck out, resulting in failure to close or open, disassemble and clean the solenoid valve, and then install it again.
