Electric valves do not work after electrification
Check power wiring is not good re-wiring and connector connection
Check whether the power supply voltage is in the working range - adjusting the normal position range
Whether the coil is detached re-welded
Short Circuit of Coil Replacement of Coil
Whether the working pressure difference is inappropriate adjusting the pressure difference or replacing the appropriate electric valve
Excessive Fluid Temperature Replacement of Equivalent Electric Valve
The main valve core and the moving iron core of the electric valve are stuck by impurities cleaned. If the seal is damaged, the seal should be replaced and the filter installed.
The liquid viscosity is too high, the frequency is too high and the service life has reached replacement products
Electric Valve Can't Close
Damaged Seals of Main Valve Core or Iron Moving Core Replacement of Seals
Is Fluid Temperature and Viscosity Excessively High Replacement of Counterpart Electric Valve
Impurity enters electric valve to produce valve core or movable iron core for cleaning
Spring life has arrived or deformed replacement
Clogging of Balance Hole of Throttle Hole Timely Cleaning
Too high working frequency or service life has reached product selection or updating
Other Conditions of Electric Valves
Internal Leakage Check whether the seal is damaged and whether the spring is not assembled properly
Outer Leakage Loose Connection or Failed Seal Tighten Screw or Replace Seal
There is noise when electrifying the firmness on the head is loosened and tightened. Voltage fluctuation is not within the allowable range, adjust the voltage. Impurities or irregularities on the suction surface of iron core should be cleaned or replaced in time.
