AP Racing Proportioning Valve
The screw type proportioning valve CP3550-14 offers infinite adjustment within the limits of normal brake operation. With the cap screwed fully in no reduction in output pressure occurs, with the cap screwed fully out, output pressure is reduced to approximately 1/3rd of input pressure.
To obtain the best performance using this valves, the brake balance should be biased towards the rear so that with the valve piped in to the rear line and screw cap right in (clockwise) where virtually no reductions occurs, the balance is as much to the rear as will ever be needed. screwing the cap outwards to a lower setting will progressively reduce the rear line pressure giving more bias to the front, for use when more grip is available.
