Height Control Air Suspension Valve with Integral Reverse DumpThe 54341 Series relies on negative air pressure to actuate the dump feature. This feature allows the seamless integration of the reverse dump valve into the trailer parking brake system. When parking brakes are set, the negative pressure that allows the brakes to lock will also allow the dump feature to be actuated. The negative air pressure allows the dump valve to return to its "normally open" state and exhaust the trailer air suspension.
