The electric valve does not work after power is applied

- Mar 17, 2017 -

Check if the power supply wiring is defective → rewiring and connecting the connector

Check if the supply voltage is within ± operating range - → to the normal position range

Whether the coil is off welding → re-welding

Short circuit → replace the coil

Whether the work pressure is not appropriate → adjust the pressure difference → or replace the commensurate electric valve

Fluid temperature is too high → replace the commensurate electric valve

There are impurities so that the main valve spool and moving core of the electric valve stuck → cleaning, if sealed damage should be replaced seal and install the filter

Liquid viscosity is too large, the frequency is too high and life has to change the product
