Full Function (FF2) Valve
For trailer systems only, the Full Function (FF2) Valve provides trailer air system service brake and spring brake functions, meeting all mandatory FMVSS-121 regulations, with a single valve.
The economical single valve approach is perfect for single and tandem axle applications. The system is easy to install, easy to maintain, easy to troubleshoot and easy to retrofit to your old multi-valve system to meet safety standards.
With a built-in pressure protection and anti-compounding it updates air brake system to the latest level of the law and eliminates broken foundation components due to compounding of spring brake. Compounding happens when the parking/spring brake and the service chamber are both applied at the same time.
This combination is powerful enough to destroy brake adjusters, distort drums and twist S-cams.
