Description
What does an ABS solenoid modulator valve do?
This ABS solenoid modulator valve plays a critical role in the anti-lock braking system by modulating brake pressure to prevent wheel lock-up during deceleration. Built with high-strength components, it ensures precise pressure modulation in response to signals from the ABS electronic control unit, maintaining vehicle stability under heavy-duty conditions.Vehicle and system compatibility
The component is engineered for compatibility with WABCO systems and is suitable for use in heavy commercial vehicles such as trucks, buses, and tractors. This specific unit features M22x1.50 ports and operates at a maximum pressure of 11 Bar, ensuring reliable performance within the pneumatic brake circuit.Installation and maintenance guidance
For workshop technicians, installation requires careful attention to the 24V DC electrical connection (ED 5% / 5 min <1.65 A) and the bayonet male connector type. Ensuring clean, dry air supply to the M22x1.50 ports is essential to prevent premature wear of the internal solenoid mechanisms.System troubleshooting
Regular inspection of the electrical connections and port seals can help prevent system errors or pressure fluctuations in the braking circuit. Consult your authorized distributor for more information.OE cross-reference
