Function of the Relay Valve

1. Air Pressure Amplification & Distribution – The relay valve receives a control signal from the foot valve (brake pedal) and quickly delivers high-pressure air directly from the air reservoir to the brake chambers, reducing response time.

2. Balanced Braking Force – It ensures consistent air pressure application across multiple brake chambers, preventing uneven braking.

3. Reduces Brake Lag – By positioning the relay valve closer to the brake chambers (instead of relying solely on the foot valve), air travels a shorter distance, enabling faster brake engagement.

Key Features of Relay Valves

• Durable Construction – Made from high-strength materials (aluminum or stainless steel) to withstand harsh conditions.

• Fast Response Time – Minimizes delay in brake application, crucial for heavy-load vehicles.

• Integrated Safety Mechanisms – Some models include anti-compounding features to prevent over-braking.

• Modular Design – Allows for easy maintenance and replacement.

• Compatibility – Works with dual-circuit air systems for redundancy in case of failure.
