TR289714 QR1C Quick Release and Double Check Valve Torque Parts LLC
DESCRIPTION The Bendix® QR-1CTM is a dual function valve. The valve's primary function is to serve the emergency side of a spring brake actuator as a quick release valve. In addition, it functions as an anti-compound device. The double check valve prevents a service and emergency brake application from occurring simultaneously.

FF2 Full Function Trailer Brake Valve 3/4
An engine-driven compressor provides the air, which is constantly being replaced and never needs to be changed. Also, pedal effort is minimal, because it simply involves depressing a treadle valve that sends air to the brake relay valves. The air does need to be kept clean and dry, but the air dryer handles that.

When the anti-compounding feature is used, removal of the exhaust cover exposes a 1/8" pipe thread balance port. All ports on the valve are identified. GENERAL OPERATION The rapid reaction of the R-8TM valve to changes in control pressures is in part due to the relatively small volume of air required between the valve cover and the relay piston.
