It manages air supply from two reservoirs, allowing the braking system to remain functional even if one reservoir loses pressure. The valve provides service brake priority and includes a built-in control port to prevent brake compounding. It is typically replaced when air leaks, parking brake malfunctions, or compliance issues with FMVSS 121 arise.
