Description
Bendix SR-7 Spring Brake Valve - K048634.

The Bendix® SR-7™ spring brake modulating valve is used in conjunction with a dual air brake system and spring brake actuator and performs the following functions:

1. Provides a rapid application of the spring brake actuator when parking.

2. Modulates the spring brake actuator application using the dual brake valve should a primary failure occur in the service brake system.

3. Prevents compounding of service and spring forces.

The valve has one park control, one service control, one supply, one balance, four delivery NPTF ports, and an exhaust port protected by an exhaust diaphragm. The valve incorporates two mounting studs for mounting the valve to the frame rail or cross member (where applicable).
