1. that the electric two-way valve does not work after being energized, check whether the power supply wiring is defective → rewire and connect the connector to check whether the power supply voltage is in the working range → adjust the normal position range to check whether the coil is deselded → reweld the coil short circuit → replace the coil to check whether the working pressure difference of the coil is inappropriate → adjust the pressure difference → or replace the matching electric valve fluid temperature of the matching electric valve is too high → replace the matching electric valve with impurities to check valve cleaning, if the seal is damaged, replace the seal and install the filter. The liquid viscosity is too high, the frequency is too high and the service life has reached → replace the product 2.. The electric two-way valve cannot close the main valve core or iron movement
1. electric two-way valve does not work after being energized
Check whether the power supply wiring is defective → rewire and connect the connector
Check whether the power supply voltage is within ± operating range → adjust to normal position range
Whether coil desoldering → Re-weld
Short circuit of coil → Replace coil
Is the operating differential pressure inappropriate → adjust the differential pressure → or replace the appropriate electric valve
The fluid temperature is too high → replace the appropriate electric two-way valve
Impurities cause the main valve core and moving iron core of the electric two-way valve to be stuck → Clean it. If the seal is damaged, replace the seal and install the filter.
The liquid viscosity is too high, the frequency is too high and the life has reached → replace the product
2. electric two-way valve cannot be closed
The seal of the main valve core or iron moving core is damaged → Replace the seal
Whether the fluid temperature and viscosity are too high → Replace the corresponding electric valve
Impurities enter the valve core or moving iron core of the electric two-way valve → clean
Spring life reached or deformed → Replace
Blocking of orifice balance hole → timely cleaning
The operating frequency is too high or the service life has reached → re-select the product or update the product
