It meters air pressure from the supply tanks to the service brake chambers proportionally to pedal force, ensuring separate front and rear circuits for safety. Common reasons for replacement include air leaks from the valve, sticking pedal, or uneven braking. The valve features 3/8-inch NPT ports for supply, delivery, and an auxiliary function.
