Hi Axle, hows your car coming along? Not seen you on here for ages. It is in the rear circuit, it limits the pressure to the rears under heavy breaking.
One really important point, the valve must go in the brake circuit after the pressure switch for the brake lights. If it is before the brake lights could turn off if you go really hard on the brakes as the valve will cut in and drop the pressure.
