Electromagnetic valve description:

The solenoid valve is an industrial equipment controlled by solenoid, which is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Electromagnetic 

valves are controlled by the electromagnetic effect, and the main control method is controlled by relays.

The solenoid valve does not work after being powered on;

Check if the power supply wiring is poor → Rewire and connect the connectors to check if the power supply voltage is within ± working range - → Adjust to the normal position range to check if the coil is 

desoldered → Re weld the coil for short circuit → Replace the coil to check if the working pressure difference is inappropriate → Adjust the pressure difference → Or replace the proportional solenoid valve. 

The fluid temperature is too high → Replace the proportional solenoid valve with impurities that cause the main valve core and moving iron core of the solenoid valve to jam → Clean it. If there is any seal 

damage, replace the seal and install the filter. The liquid viscosity is too high, the frequency is too high, and the service life is over → Replace the product

The solenoid valve cannot be closed;

The sealing components of the main valve core or iron moving core are damaged → replace the sealing components to check if the fluid temperature and viscosity are too high → replace the corresponding 

electromagnetic valve with impurities entering the electromagnetic valve core or moving iron core → clean the spring life has expired or deformed → replace the balance hole blockage of the throttle hole →

 clean in a timely manner if the working frequency is too high or the service life has expired → choose a new product or update the product
