What is an ABS Dual Relay Valve?

The ABS dual relay valve is a critical component that ensures the safe and controlled operation of the braking system. This valve works in harmony with the anti-lock braking system (ABS) to control brake pressure and prevent wheel lock-up. The dual relay valve maintains the vehicle's balance during braking, especially by regulating brake pressure quickly and accurately.

Working Principle of an ABS Dual Relay Valve
  • Pressure Control: Adjusts brake pressure quickly and reduces or increases braking force when necessary.
  • ABS Integration: Prevents wheel lock-up during braking by evaluating data from ABS sensors.
  • Stability and Safety: Increases driving safety by maintaining the vehicle's balance during braking.
Components of an ABS Dual Relay Valve
  • Dual Relay Mechanism: Provides brake control by regulating brake pressure in two directions.
  • Brake Pressure Sensors: Monitors brake pressure and transmits information to the ABS control unit.
  • Valve Body: Robust structure that houses all the components of the relay valve.
  • Sealing Gaskets: Ensures that the pressure is directed correctly.
  • ABS Control Unit Connection: Interacts with the ABS system and ensures that the valve works automatically.
Advantages of ABS Dual Relay Valves
  • Precise Braking Control: Prevents wheel lock-up by regulating brake pressure quickly and precisely.
  • Brake Safety: Increases the vehicle's road grip during braking and supports safe braking.
  • Balanced Driving: The valve, which works in integration with ABS, ensures driving safety by maintaining the vehicle's balance during sudden braking.
  • Long-Lasting Use: An ABS dual relay valve made from high-quality components supports the smooth operation of the braking system.
ABS Dual Relay Valve Faults and Symptoms
  • ABS Light Illumination: The ABS light illuminating on the instrument panel indicates a problem with the system.
  • Stiffening of the Brake Pedal: The brake pedal may become stiffer than normal when the valve malfunctions, and braking may become difficult.
  • Lengthened Braking Distance: The braking distance may increase when the valve cannot regulate pressure properly.
  • Vibration During Braking: If excessive vibration or shaking is felt during braking when ABS is engaged, the valve may be faulty.
Maintenance of ABS Dual Relay Valves
  • Valve Body Cleaning: The valve body should be cleaned regularly and kept free from dirt and dust.
  • Brake Fluid Check: It should be ensured that the brake fluid level is sufficient and should be topped up when necessary.
  • Maintenance of ABS Sensors: ABS sensors should be checked regularly.
  • Control of Sealing Gaskets and Connections: The integrity of the gaskets inside the valve should be checked regularly to ensure there are no pressure leaks.
Conclusion

The ABS dual relay valve is a critical component that enhances safety in the braking system and ensures braking control with precision. The VADEN ORIGINAL ABS dual relay valve provides long-lasting and reliable performance in commercial vehicles.
