The six-horizontal, two-vertical delivery layout is the feature that most clearly distinguishes the Bendix Air Brake Relay Valve. With the Bendix K022372, eight delivery positions give the valve flexibility in how brake lines approach the body, while a single 1/2-14 NPT supply port feeds the relay circuit. That relay response happens at 4.0 psi, the point where the valve begins directing air to the chambers. This combination gives brake-system buyers a useful layout, supply, and operating-pressure profile for replacement matching.
