Description

What does a relay valve do?

This relay valve plays a critical role in the compressed air brake system of heavy commercial vehicles by ensuring rapid air pressure transfer triggered by a pilot signal. Built with high-strength components, it is designed to withstand demanding operating conditions while maintaining precise control over braking forces.

Vehicle and system compatibility

The unit is compatible with Scania, Iveco, Faun, Leyland, Liebherr, Van Hool, and Volkswagen Truck vehicles. It is also engineered to work with WABCO systems to ensure seamless integration within the pneumatic braking circuit.

Installation and maintenance

For proper installation, technicians should verify that the M22x1.5 and M16x1.5 ports are correctly aligned with the chassis connections. This component operates at a maximum pressure of 10 BAR and should be inspected during routine brake system maintenance to prevent pressure loss.

Operational requirements

When replacing this valve, ensure the mounting location between the main air reservoir and the brake chambers is clear of debris to maintain optimal performance.
