Intended Application
- Used on trucks, buses and trailers that require safe control of spring brakes in the event of a pressure failure in the system.
- Allows the spring brakes to remain disengaged when there is sufficient air pressure in the system. If the system pressure falls below a critical threshold, the valve reverses its operation and automatically activates the parking brakes.
