EVR20 Refrigeration Electromagnetic Valve


The opening and closing of the EVR refrigeration electromagnetic valve is controlled by the electromagnetic attraction generated by the current passing through the electromagnet. As the Solenoid Valve inlet and outlet diameter is larger, its open mode can be divided into direct open and indirect open two. Directly for small diameter solenoid valve, indirectly for large diameter solenoid valve.

Troubleshooting of EVR Refrigeration Solenoid Valves:

Fault phenomenon 1: EVR solenoid valve does not work after power


Elimination method: check the power supply wiring whether bad --- new connectors and wiring connection, check whether the power supply voltage is working in the plus or minus range --- to adjust to normal position, whether the coil desoldering --- welding coil short-circuit again --- change the line circle, working pressure difference is not appropriate to adjust the differential, or replacement of proportion of solenoid valve, fluid temperature is too high and change of proportion of solenoid valve, have impurities to make electromagnetic valve of the main valve core and the moving core card dead --- cleaning, should replace the seal and install any seal damage filter, the liquid viscosity is too large, the frequency is too high and life and have to exchange products


Malfunction phenomenon 2: EVR solenoid valve cannot be closed

Elimination method: the main valve core or moving iron core of the seal is damaged, replace the seal, fluid temperature, viscosity is too high to replace of the solenoid valve, with impurities into the solenoid valve core production or moving iron core --- cleaning, spring had come to life or deformation and replacement, orifice balance hole plugging and timely cleaning, working frequency is too high, or life and have to re-election product or update other fault condition: internal leakage to check whether the seal is damaged, whether the spring assembly adverse external leakage to joint looseness or seal has been bad, screw or replace seal electricity from time to tome noise --- leader on solid loose, tighten. Voltage fluctuation is not allowed, adjust the voltage. Iron core suction surface impurities or uneven, timely cleaning or replacement.
