Bendix A80070X is a relay valve for air brake systems. A relay valve works as a remote control station for the brakes: a small control air signal tells it to pass a much larger flow of reservoir air out to the brake chambers it serves, and it exhausts that air again when the signal is released. That is what lets the chambers fill and vent quickly instead of waiting on a long air line. An audible air leak at the valve with the parking brake released is the usual sign of trouble, though a chamber seal or a check valve in the circuit can be the real source, so the circuit is worth checking too.
