Description

What does an ABS solenoid modulator valve do?

This ABS solenoid modulator valve serves as a critical component within the anti-lock braking system of heavy commercial vehicles. It functions by modulating brake pressure through electromagnetic signals from the ECU to prevent wheel lock-up during deceleration. Built with high-strength components, this valve ensures reliable pressure control under demanding braking conditions.

Vehicle and system compatibility

This component is compatible with WABCO systems and is suitable for use in heavy commercial vehicles such as trucks, buses, and tractors. It is engineered to meet the rigorous requirements of professional workshop technicians and fleet managers seeking reliable braking performance.

Technical specifications and installation

The unit features M22x1.5 port sizes and is designed for 24V DC electrical connections, specifically supporting a 75% duty cycle at 1.65 A. For correct installation, ensure the bayonet connector is properly seated and the maximum operating pressure of 11 Bar is not exceeded.

Maintenance and troubleshooting

Regular inspection of the solenoid connections and port seals is recommended to maintain optimal braking response. If uneven braking or ABS warning lights appear, check the valve's electrical integrity and pressure regulation capability.
