1, the electromagnetic valves do not work after power -
Check the power wiring is bad → re-wiring and connectors to connect
Check power supply voltage is within ± scope of work - → tone caused by the scope of its normal position
Coil is re-welding Sealing-off →
→ replace the coil short-circuit coil
Working pressure is inappropriate to adjust the pressure → → or replacement of the electromagnetic proportional valve
Fluid temperature is too high → commensurate with the electromagnetic valve replacement
Impurities so that the main solenoid valve spool and the moving core stuck → cleaning and, if seal is damaged seals should be replaced and installed filters
Too much liquid viscosity, the frequency is too high and life has come to replace the product →
2, the electromagnetic valve can not be closed
Moving the main spool or iron core of the seal is damaged seals replaced →
Fluid temperature, viscosity is too high to replace their counterparts in the electromagnetic valve →
Impurities into the solenoid valve spool or moving core capacity washing →
Spring has come to life or deformation → replace
Orifice hole to plug → timely clean balance
Operating frequency is too high or life has come to re-election of products or product →
3, other conditions
→ check inside the leak seals is damaged, whether the assembly of non-performing spring
Outer → connections loose or leaking seals have been broken → screws or replace seals
Power when the solid pieces of noise → head loose, tighten. Voltage fluctuation is not permitted within the scope, adjusting the voltage. Core Pull-surface impurities or uneven, timely cleaning or replacement. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve Three way ball valve V Type Ball Valve
