Solenoid valve power does not work

Check the power wiring is bad → re-wiring and connectors to connect
Check whether the supply voltage is in the range of ± work - → tone caused by normal position range
The coil whether sealing off → re-welding
Coil short → Replace the coil
Working pressure is inappropriate → adjust the differential pressure → commensurate with or replace the solenoid valve
Fluid temperature is too high → Replace the solenoid valve commensurate
Impurities solenoid valve main spool and dynamic core stuck cleaning → if the seal is damaged replace the seal and install the filter
Liquid viscosity is too large, the frequency is too high, and life replacement product to →pneumatic hand valve
Solenoid valve can not be closed
The main spool or moving iron core seals damage → Replace the seals
Fluid temperature, the viscosity is too high → counterparts replacement solenoid valve
Cleaning impurities into the solenoid valve spool production or moving core →
Spring to life or deformation → Replace
The throttle Kong Pingheng clogging → timely cleaning
Working frequency is too high or too the life → reelection products or updated products
Other
Internal leakage → Check the seals for damage, the spring assembly of non
The external leakage → loose connections or seal has been broken → screws or replace the seals
Energized noise → chieftain fasteners to loosen and tighten. Voltage fluctuation is not within range, adjust the voltage. The core pull surface impurities or uneven, cleaned or replaced in a timely manner.stainless steel pneumatic cylinders
