What is an Electromagnetic Regulating Valve?

In the automotive industry, the electromagnetic regulating valve, commonly known as the ABS regulating valve, is a crucial component of the Anti-lock Braking System (ABS).

ABS Anti-lock Braking System

The ABS system is an electronic system that controls and monitors the vehicle's speed during braking. It works with the conventional braking system to enhance the vehicle's active safety. In the event of ABS failure, the conventional braking system will still function. The ABS system mainly consists of components such as the ECU (Electronic Control Unit), ABS solenoid valve, wheel speed sensors, and wiring harness.

How Does the Electromagnetic Regulating Valve Work?

The ABS solenoid valve is a key actuator in the ABS system. It receives electrical signals from the ECU to control the braking chamber by applying, releasing, or maintaining pressure.

Triggering Mechanism: When the slip ratio of a particular wheel exceeds a certain threshold, the system detects the wheel locking up and will release the brake pressure on that wheel to allow it to regain traction and continue rotating.

Importance of the Electromagnetic Regulating Valve

The most important function of ABS is not to shorten the braking distance, but to maintain the vehicle's directional stability during braking. This ensures that the vehicle remains controllable even under heavy braking conditions, thereby enhancing safety.

Signs of Electromagnetic Regulating Valve Failure

In the holding pressure state: Abnormal pressure in the brake chamber.
In the pressure increase state: The brake chamber pressure does not increase in steps.
In the pressure release state: The brake chamber pressure does not decrease in steps.
