Description

What does a relay valve do?

This relay valve acts as a critical pneumatic control unit within the air brake system of heavy commercial vehicles. By receiving a pilot signal from the brake pedal and feeding air directly from the nearest reservoir to the brake chambers, it significantly reduces air transmission lag. This ensures rapid engagement and reliable release speeds for safer braking operations.

Vehicle compatibility

This component is specifically designed for compatibility with Renault Trucks vehicles. It is engineered to withstand demanding operating conditions while maintaining precise pressure regulation throughout the braking circuit.

Technical specifications and installation

The unit is configured with M22x1.5 VOSS Port 1, M16x1.5 VOSS Port 2, and M16x1.5 VOSS Port 4, supporting a maximum operating pressure of 10 BAR. Technicians should verify port sizes and pressure requirements during installation to ensure perfect fitment and system integrity.

Maintenance and performance

Regular inspection of the pneumatic connections and port integrity can prevent air leaks and ensure consistent braking response times across the vehicle fleet.

OE cross-reference

303.01.0004 (Relay Valve Relay Valves) is the equivalent of the Renault Trucks OE number. This part directly replaces Renault Trucks OE number 7701012770.
