Air Pressure Relay Valve

An air pressure relay valve is a component used in vehicular brake systems. It is part of the supply class Vehicular Brake, Steering, Axle, Wheel, and Track Components, which falls under the supply group Vehicular Equipment Components.

The air pressure relay valve is responsible for regulating and controlling the air pressure in the brake system of a vehicle. It helps to ensure that the correct amount of air pressure is distributed to the different brake chambers, allowing for efficient and effective braking.

The relay valve works by receiving air pressure from the vehicle's air compressor or air reservoir. It then regulates this pressure and distributes it to the appropriate brake chambers. This helps to ensure that the brakes are applied evenly and smoothly, allowing for safe and controlled braking.

In summary, an air pressure relay valve is a crucial component in the brake system of a vehicle. It helps to regulate and control the air pressure, ensuring that the brakes function properly and provide safe braking performance.
