Is the electric end of the electromagnetic reversing valve attracted or pushed open?

The function of the electric end of the electromagnetic reversing valve is to attract and close the valve core. Its working principle and process are as follows:

How it works

The electromagnetic reversing valve is mainly composed of a valve body, a valve core, an electromagnet and a spring. Its working principle is based on the interaction between the magnetic force generated when the electromagnet is energized and the spring force, and the fluid channel is changed by controlling the movement of the valve core to achieve the reversing function.

The process of getting electricity

Energized state: When the electromagnet at one end of the electromagnetic reversing valve is energized, the electromagnet generates magnetic force. This magnetic force will attract the valve core, causing the valve core to move in the direction of the electromagnet (that is, the direction of attraction) against the spring force. As the valve core moves, the fluid channel is switched to the corresponding position, thereby realizing fluid reversal.

Power-off state: When the electromagnet is powered off, the electromagnetic force disappears. At this point, the spring force comes into play, pushing the valve core back to its original position. The reset of the valve core restores the initial fluid passage and prepares for the next reversal.

Performance in practical applications

Suction action: In the actual application of the electromagnetic reversing valve, after the electromagnet at the power end is energized, the valve core will be quickly pulled in to the corresponding position. This pull-in action is a key step for the electromagnetic reversing valve to achieve the reversing function.

Reversing effect: By repeatedly controlling the energization and de-energization of the electromagnet, the electromagnetic reversing valve can accurately control the flow direction of the fluid. This reversal effect is widely used in industrial automation control systems, such as controlling the movement direction of hydraulic cylinders.
