​

Relay emergency valves are commonly used on pre-121 trailers and in current off-highway braking systems and trailer converter dollies. The relay emergency valve is a dual function valve. Under normal braking conditions, it serves as a relay valve, applying and releasing the service brakes. The emergency portion of the valve senses supply line pressure and should pressure in the supply line fall below a predetermined minimum, the valve will automatically apply the vehicle service brakes from its own protected reservoir.
RE-6 relay emergency valves are piston operated & provides easy removal of the inlet/exhaust valve cartridge assembly without line removal.
The RE-4 and RE-6 are interchangeable in both fit and function.
