On some trucks & trailers, the distance from the brake chambers to the foot valve is too far to cause immediate application of the brake when the foot valve is depressed. This is called brake lag. To correct this situation, a relay valve is installed near the rear brake chambers. A large diameter pipe is connected between the service reservoir and relay valve. The air line from the foot valve to the relay valve now becomes a control line that signals to the relay valve the amount of air to be drawn from the service reservoir for faster application of the brakes.

Air Suspension Control Valves are used to automatically control the vehicle’s ride height by inflating and deflating the air suspension bellows to adjust for variations between loaded and unloaded vehicles. They are also used for cab suspensions to provide ride comfort for the operator and for bus suspension application, including kneeling capability.

When air is compressed, the compressor takes in water vapor with the air, compresses the water vapor & puts it into the system as liquid water. Any water that accumulates in the vehicles air lines damages seals, valves & removes lubricants. In cold weather it can freeze blocking air lines & damaging air system components. The Air Dryer protects the vehicles air systems & components from this by drying the air passing through the air tanks and into the system via the desiccant cartridge. A coalescing cartridge has additional material to trap oil & aerosol particles. Water is then removed from the desiccant via a backflow of dried expanded air.

Hand brake valves are used to activate & release the parking brake. In the control position, the pneumatic brake in the trailer can be released so that the effectiveness of the spring brake in the towing vehicle can be checked. Variants with an emergency release device prevent automatic braking of the spring brake in the event of a defective parking brake circuit.
