DESCRIPTION

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. QR-1C

™

valve delivery port (2) connected to emergency

port of spring brake.

2. QR-1C

™

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. QR-1C

™

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. These double check valves contain a beaded seat

cap nut (Figure B). The bias design minimizes low differential

leakage.
