1.applicability The fluid in the pipeline must be consistent with the medium calibrated in the selected solenoid valve series. The temperature of the fluid must be less than the calibration temperature of the selected solenoid valve. The maximum working pressure difference should be less than the maximum calibration pressure of the solenoid valve; generally, the solenoid valve works in one direction, so pay atte

1. Solenoid valves are divided into three categories in principle: 1) Direct acting solenoid valve: Principle: When energized, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, the spring presses the closing member on the valve seat, and the valve closes. Features: It can work no

1. The solenoid valve does not work after being energized Check whether the power wiring is bad, re-wiring and connector connection Check whether the power supply voltage is in the working range -, adjust the normal position range Whether the coil is desoldered and re-soldered The coil is shorted, replace the coil Whether the working pressure difference is inappropriate, adjust the pressure difference

First, check whether the solenoid valve solenoid coil is faulty. Give the two-position valve an open or close signal on the DCS, and then see if the solenoid valve gains or loses power. Generally, you can listen to the sound at the scene. If you can't hear it, there must be a problem with the coil. As for the solenoid valve itself, is there a problem? If there is a problem with the solenoid coil, first chec

-What is solenoid valve? Solenoid valve is an industrial equipment controlled by electromagnetic, and it is an automatic basic component used to control flfluid. It belongs to an actuator and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flflow, speed and other parameters of the medium. The solenoid valve can cooperate with different circuits to achieve the de
