Sample of valve body

The Electromagnetic Valve Fault and Eliminate:
electromagnetic valve does not work after the power supply:
1, check the power supply wiring whether bad -)

connectors and wiring connection again;
2, check whether the power supply voltage in the plus or minus working range --) to switch to normal position;
3, whether the ring

sealing off -) to welding;
4, coil short circuit, replace the coil;
5, differential pressure is not appropriate to work -) -) or replacement of proportion adjustment pressure

difference electromagnetic valve;
6, fluid temperature is too high -) change of proportion of electromagnetic valve;
7, have impurities to make electromagnetic valve of the

main valve core and the moving core card die -) cleaning, such as seal damage the seal and install the filter should be changed;
8, the liquid viscosity is too large, high

frequency and life expectancy has to -) replacement products.

(2) the solenoid valves can't shut down:
1, the main valve core or moving iron core of seal is damaged, replace the seal;
2, fluid temperature, viscosity is too high -) change

of the electromagnetic valve;
3, have impurities into the solenoid valve core or moving iron core -) for cleaning;
Four, spring life have to or replace the spring deformation
5, orifice balance hole jam --) timely cleaning;
6, working frequency is too high, or life has to -) election products or replacement products.
(3) other situations:
1.internal leakage, check whether the seal is damaged, the spring is bad assembly.
2, outside leakage -) joint looseness or seal has bad -) screw or replace the seal;
3.electricity from time to tome noise -) leader on fasteners loose, tighten. Voltage fluctuation is not allowed within the scope of adjust voltage. Core surface impurities or

uneven absorption, clean or replace in a timely manner
