WABCO ABS Traction Control Valve

Closed until a signal arrives, the WABCO ABS Traction Control Valve blocks airflow as a normally closed device wired for 12-volt systems. This valve exhausts through a 4 mm port to release pressure quickly once the ABS module calls for it. It holds pressure up to 10.2 bar while integrated into the traction control circuit alongside the vehicle's ABS network. Wheel slip detection triggers the valve to cut engine power delivery during acceleration on low-traction surfaces. Wired into the ABS harness, the WABCO 4721707970 reacts within milliseconds of a slip event.
