Bendix Brakes Air Brake Control Valve

Bendix Brakes Air Brake Control Valves: The OEM Standard for Commercial Vehicles

When the load is heavy and the stakes are high, the components directing airflow through your brake system have to perform without compromise. Bendix Brakes has long been the name fleet operators and OEM manufacturers reach for when specifying air brake control valves — and with good reason. Valves direct the flow and release of air throughout an air brake system, a critical job for the network of compact components located on an 80,000-pound vehicle. Bendix engineers these parts to meet exactly that challenge.

Why Bendix Sets the Standard in Air Brake Control Valves

Bendix has a long and notable history of being the first to introduce landmark air brake system technologies, including air compressors, air dryers, and ABS, to the North American commercial vehicle market. That legacy of innovation carries directly into their air brake control valve lineup. Genuine Bendix valves — whether new or remanufactured — reflect today's highest engineering standards and comply with all federal safety regulations. In fact, genuine Bendix is the industry-standard valve system chosen by leading OE manufacturers throughout North America.

Bendix Commercial Vehicle Systems, a member of Knorr-Bremse, develops and supplies leading-edge active safety technologies, energy management solutions, and air brake charging and control systems and components for medium- and heavy-duty trucks, tractors, trailers, buses, and other commercial vehicles. This global engineering depth means every control valve they produce benefits from world-class research and real-world validation.

A Wide Range of Control Valve Designs

Bendix air brake control valves span a broad spectrum of applications across the drivetrain and trailer system. Bendix-style air valves serve vehicles equipped with air brakes — heavy-duty trucks, buses, tractors, and more — including bobtail, check, air control, governor, pressure protection, quick release, relay, spring brake, and tractor protection valves. Notable product lines include:

• MV-3 Manifold Control Dash Valve — The Bendix MV-3 Air Brake Manifold Control Dash Valve is engineered for precision and reliability in heavy-duty truck braking systems, controlling air pressure and distribution through the manifold to ensure accurate brake response and smooth modulation.
• R-12P Relay Valve — A zero-hysteresis, zero-crack-pressure relay valve, the R-12P boosts the control signal from the tractor to the trailer's service relay valves and can also serve as a slave to the ABS system to provide antilock functionality on remote axles not directly sensed by ABS.
• SR-2 Spring Brake Priority Valve — The SR-2 fills the spring brake chambers and the reservoir simultaneously, ensuring sufficient service brake pressure in the reservoir when the spring brakes are released.
• PR-3 Pressure Protection Valve — Normally used to supply the air suspension system on the trailer, the PR-3 is offered in different pressure settings and can also be used for other accessories as needed.

Engineered for the Demands of Tomorrow's Fleet

Commercial vehicles are becoming more sophisticated and compressed air requirements are increasing — that's why Bendix is always developing and testing the next generation of valves and control system components designed to enhance and improve vehicle performance. Whether you're maintaining a single work truck or managing a full commercial fleet, Bendix air brake control valves deliver the reliability and federal compliance that keep vehicles safe and on the road.
