WABCO EBS Proportional Relay Valve
Achieve superior control and smooth braking performance for your trailer’s Electronic Braking System (EBS) with the WABCO EBS Proportional Relay Valve. This component acts as the conductor of your trailer's EBS, translating electronic signals from the EBS control unit into precise modulations of air pressure within the braking system. Featuring WABCO's innovative Proportional Solenoid technology, this valve ensures a linear relationship between the electrical signal and the resulting air pressure, enabling smooth and graduated braking application. With these features, the WABCO 4802020040 delivers exceptional driver feel and minimizes the risk of wheel lockup during hard braking or on slippery surfaces.
