The driver uses the lever to manually apply and modulate the trailer service brakes independently of the tractor, allowing for gradual reduction of incoming air pressure (typically 50-120 PSIG). It features a locking mechanism so the operator can set and hold a desired output pressure. These valves are commonly replaced when they develop internal air leaks, the lever becomes sticky or fails to modulate pressure smoothly, or the locking feature wears out.
