DESCRIPTION
The relay valve in an air brake system functions as a relay
station to speed up the application and release of the
brakes. The valve is normally mounted at the rear of the
vehicle in proximity to the chambers it serves. The valve
operates as a remote controlled brake valve that delivers
or releases air to the chambers in response to the control
air delivered to it from the foot brake valve.
