Factory wholesale Gooseneck Trailer - 6 port relay valve use for 3 axle brake system – MBP

The relay valve is used at the end of a long pipeline to make the compressed air in the air reservoir fill the brake chamber quickly, such as in the braking system of a trailer or semi-trailer.

Differential relay valve is generally used. The driving and parking system shall be prevented from operating simultaneously, and the force overlap in the combined spring brake cylinder and spring brake chamber, so as to avoid overload of mechanical transmission components to make the spring brake cylinder charge and exhaust rapidly.

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.

The RE-4 and RE-6 relay emergency valves are piston operated and are available in both remote and reservoir mount configurations. Both valves provide 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.
