Push-Pull Valves
Push-pull valves are normally-closed, on/off control valves used to release the parking brakes on air brake vehicles as well as control other accessory systems. They generally have a predetermined release pressure setting that will cause the valve to "pop off" if system pressure drops too low.
These valves are usually found on the dashboard in the cab of the truck.
