Stainless steel solenoid valve is an industrial automation system in the actuator, which accepts the electronic control signal can automatically open and close the valve, to achieve the pipeline dielectric on or off control. Stainless steel solenoid valve works: Normally closed: When the coil is energized, the solenoid core pulls, the pressure relief hole opens, the main piston is pushed by the medium pressure, opens the main valve port, the media circulation. When the power is off, the main valve port is closed and the media is cut off. Normally closed: contrary to normally open.
In use, the stainless steel solenoid valve stuck is the most common kind of failure, the following, simple analysis of the reasons for the stuck.
Stainless steel solenoid valve slide valve sleeve and spool with the gap is too small, when there are mechanical impurities into or less oil, easy to stuck. You can use the wire from the hole of the solenoid valve into the hole, and then make it back. This is only a temporary first aid method, the fundamental solution is to remove the stainless steel solenoid valve, and then remove the spool and spool sleeve, clean, so that the valve spool in the flexible action. When disassembling, it is necessary to pay attention to the assembly sequence and wiring position of the components of the solenoid valve for re-installation and wiring. To check the oil mist nozzle is blocked, the oil is sufficient.
