Direct acting solenoid valve: Principle: When powered on, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat and open the valve; When the power is cut off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, causing the valve to close. Characteristics: It can work normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25mm.
The above describes the general principle of solenoid valves
In fact, based on the temperature, pressure, and other conditions of the flowing medium, such as pressure in the pipeline and no pressure in the self flowing state. The working principle of solenoid valves is different.
For example, in the self flowing state, if zero pressure starting is required, the entire coil will suck up the gate after being powered on.
And the solenoid valve with pressure state, after the coil is energized, sucks out a pin inserted into the gate body, and uses the pressure of the fluid itself to lift the gate body up
