When a single coil is powered on, the mechanical part of the valve core operates. After losing power, it returns to its original position by mechanical force. The double-coil operates mechanically when coil 1 is energized and remains in its position when it is de-energized. When coil 2 is energized, the mechanical part changes from position 1 to position 2, and remains so after the power is lost.
This type is generally: "3-position 4-way valve" or "3-position 2-way valve". Three, in layman's terms, means there are three gears: 1/0 and 1/2. When coil 1 is energized, the valve core is turned to 1; when coil 1 is de-energized, the valve core returns to 0. When coil 2 is energized, the valve core opens track 2. When coil 2 is de-energized, the valve core returns to 0. This kind of valve is very common.
Double electric control means there are two electromagnetic coils. The double coils are usually supposed to be electromagnetic directional control valves. Single-coil is always energized and the air intake is open, while the double-coil is energized instantaneously.
The slide valve of the single-coil solenoid valve is spring-reset. After the solenoid valve loses power, it will automatically reset. The double-coil solenoid valve needs to be energized on the other side of the coil to change positions.
The double-coil solenoid valve has two coils, A and B. The operation is as follows: A is not electrified, B is not electrified, and the solenoid valve is in the initial position. If A is electrified at this time and B is not electrified, the solenoid valve will act to reverse the direction.
