Product Description
Traction Relay
Features & Benefits
- Traction-control function shares the same valve body used for service-brake relay duty
- Receives electronic traction commands from the vehicle ABS control system
- Brake-air delivery comes from the nearby reservoir during normal relay operation
- Avoids adding a separate pneumatic relay valve for traction intervention
Bendix ATR-6 Traction Relay Valve
Manage normal relay braking and automatic traction-control commands through one valve with the Bendix ATR-6 Traction Relay Valve. The Bendix K078420 handles both jobs by letting the traction-control system influence axle air pressure without adding a separate relay valve. A 12V interface, two-way circular DIN connector, multiple delivery ports, and 5.5 PSI crack pressure define how it connects to the truck. With the electrical plug and air ports confirmed, one ATR-6 valve covers both relay braking and traction-control commands in the axle circuit.
