What's is the solenoid valve
The solenoid is an electromagnetic part of a valve, comprised of a coil, coretube, core and enclosure. Darhor' Vdarhor brand offers the worlds largest selection of 2-, 3- and 4-way solenoid valves, designed to handle the most demanding fluid control applications.
2-way. One inlet and one outlet, and are used to permit and shut off fluid flow. The two types of operations are “Normally Closed” and “Normally Open”.
3-way.Thesevalves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They're commonly used to alternately apply pressure to and exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal.
Solenoid valve failures and exclusion
When the solenoid valve is energized but does not work
Check the supply wiring is bad
connect wiring again and the connector is connect
Check whether the power supply voltage in the range of it
to the normal working range
The coil is seal off
welding again
The coil short coil short circuit
change coil
Working pressure is not appropriate
adjust the pressure different/or change
commensurate solenoid valve
The fluid of high temperature
change commensurate solenoid valve
The impurities make main valve and moving core no work
clearing, for example, a damaged seal
should change the seal and install filter
The liquid viscosity is too large. the frequent is
too high and life has been came
change product
Solenoid valve can not be turn off
The main valve or iron core seal is damaged
change seal
Fluid temperature/viscosity is too high
change counterpart solenoid valve
The imparities entering the solenoid valve main valve core or iron core
cleaning
Spring life has been come or deformation
change
The orifice and the balance hole are block
cleaning
The working frequent is too high or life has been came
re-election or change product
Other circumstance
Internal leakage
check whether seal is damage, spring is poor assembly
External leakage
seal loose or broken/to fastening screw or change seal
Power noise
chief fasteners loose tighten voltage fluctuation is not in
the allowed range, adjust the voltage.the iron core suction surface haveimpurities or imbalance, please timely cleaning or change
