What valves are anti-compounding valves?
Anti compounding valves are found in an air brake system on large commercial vehicles. These valves help to balance the pressure applied to the slack adjuster by simultaneously applying air to the spring brake relay when the service brake is pushed. The air is applied to the parking brake chamber as air pressure is applied to the service brake chamber thus releasing the parking brake the same amount that the service brake is applied thus "Balancing" the pressure in the brake chamber. This prevents excessive pressure from being applied to the service side and subsequently to the rod and slack adjuster. Thomas Moysey- owner A.B. CDL Training Center Waterford, CT
