The Bendix® QR-1C® 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.


The QR-1C valve is generally mounted on the axle and serves two spring brake actuators. The air connections to the QR-1C valve are as follows:
1. Valve delivery port (2) connected to emergency port of spring brake.
2. Valve balance port (1) connected to delivery of brake valve or relay valve. NOTE: If relay valve is installed on vehicle, it should be connected to the delivery side (not service or signal side).
3. Valve supply port (1) connected to delivery of park control valve.


In its standard configuration the valve is designed to deliver
within 1 psi of control pressure. However, for special
applications the valve is available with greater differential
pressure or zero hysteresis. QR-1C valves also come with
optional noise reducing foam crosses or silencers. Some
QR-1C valves can also come with biased double check
valves.
