This lever type proportioning valve provides the driver with 7 distinct settings from which to produce the most suitable braking ratio. To obtain the best performance using this valve, the brake balance should be biased towards the rear so that with the valve piped in to the rear line and set in position 7 where virtually no reductions occurs, the balance is as much to the rear as will ever be needed. Moving the control lever to a lower setting will progressively reduce the rear line pressure giving more bias to the front, for use when more grip is available.
Nominal Ratio of 0.325. Weight 180g approx. M10x1 connections.
