Height Sensing Proportioning Valve

The valve has a fixed split point when the vehicle is unloaded. The pressure is equal into and out of the valve up to the 150 psi. split point. After that the output pressure deceases on a 0.43 slope. When the vehicle is loaded the actuator lever is moved upward, allowing full hydraulic pressure to the rear brakes. Hydraulic pressure into the valve is equal to the pressure coming out of the valve at all times.
