It receives a control signal from the brake pedal and rapidly delivers compressed air from the reservoir to the brake chambers, ensuring quick, balanced braking on multi-axle setups. Commonly used on tandem axle trailers with four brake chambers, it helps reduce brake lag and provides even pressure to all wheels. The valve must be replaced as a complete unit; no repair kits are available, and it is designed for nipple-mount installation in remote relay applications.
