R7 Modulating Valve
The R-7 modulating valve is used in conjunction with a dual air brake system and spring brake actuators, and performs four functions:
1. Limits hold-off pressure to the spring brake actuators
(adjustable).
2. Provides for quick release of air pressure from the spring
cavity of the spring brake actuator allowing a fast
application of the spring brake actuators.
3. Modulates spring brake actuator application should a
failure occur in the service brake system.
4. Prevents compounding of service and spring forces.
