Product Description
4721950160 ABS Solenoid Modulator Valve for BENZ Heavy-Duty Trucks
Maintenance & Safety Warnings
- Pneumatic Safety: Exhaust all air pressure from the auxiliary and brake reservoirs before attempting removal to prevent serious injury.
- Directional Flow: Pay strict attention to the "In" and "Out" port markings; reversed installation will disable the ABS function on that wheel.
- Contamination Alert: Even tiny particles of rust or rubber from old air lines can clog the internal solenoid. Always flush the air lines before installing a new unit.
- System Calibration: After installation, a diagnostic reset is required to clear stored ABS fault codes and ensure the ECU recognizes the new modulator.
Product Overview
The 4721950160 ABS Solenoid Modulator Valve is a critical safety component manufactured by WABCO, designed for the high-demand air brake systems of Mercedes-Benz heavy-duty trucks. Its primary role is to regulate air pressure to the brake chambers during an ABS event, preventing wheel lock-up and maintaining steering control under emergency braking.
Built with a robust, corrosion-resistant housing and high-frequency response solenoids, this valve ensures millisecond-precision pressure adjustments. Whether integrated into a truck or trailer system, the 4721950160 offers the reliable "Active Safety" performance required to protect heavy cargo and drivers in extreme weather or high-speed conditions.

Frequently Asked Questions
Q: Can I use this valve on a trailer as well as a tractor unit?
A: Yes, the 4721950160 is a universal ABS modulator used extensively in both truck chassis and trailer ABS/EBS configurations.
Q: Why is my ABS light still on after replacing the valve?
A: Most ABS systems require a "Static Test" or a drive cycle (usually above 15 km/h) to clear the fault light. If it stays on, check the wheel speed sensor or the wiring harness for continuity.
Q: Does this unit include the mounting bracket?
A: This specific part number usually refers to the modulator valve itself. We recommend reusing your original bracket or purchasing the vehicle-specific mounting kit separately.
Q: How do I know if the failure is the valve or the ABS ECU?
A: If you hear a constant air leak from the valve's exhaust port while the brakes are applied, the internal diaphragm of the valve has failed. If there is no "click" sound during a diagnostic component test, the electrical coil or the ECU may be the issue.
