R-14 Relay Valve - Vertical Delivery Ports.
Relay valves are primarily used on long wheelbase vehicles to apply and release rear axle(s) service or parking brakes. They are air operated, graduating control valves of high capacity and fast response. Upon signal pressure from the service brake valve, they graduate, hold or release air pressure from the chambers to which they are connected. They are generally mounted close to the chambers they serve.
