Relay valves are primarily used on vehicles to apply and release rear axle (s) service or parking brakes. When the driver applies the brakes, air travels through the delivery (in this case signal) line to the relay valve and moves an internal piston down. This closes the exhaust and opens the delivery of air to the brakes.
