Relaying control pressure quickly to the brake chambers is the job of the Bendix Air Brake Relay Valve. The valve belongs in the service-brake pneumatic circuit, where it uses a local air supply to reduce the delay between a control signal and chamber pressure. Positioning that reservoir air near the axle is what shortens the pneumatic response distance on the Bendix 103009N. Matching the existing port arrangement and application is important because relay valves with similar housings can use different crack pressures, mounting patterns, or plumbing layouts.
