A proportioning valve is a valve that depends on fluid pressure to spread input forces to one or more output lines. The valve can increase or decrease forces for every output, it is all decided by the cross-sectional surface areas.
Brake proportional valve functionThe proportional valve is utilized in cars to help reduce the fluid pressure on the rear brakes. In vehicles that have disc brakes on the front of the vehicle but drum brakes in the rear of the vehicle, it is necessary to have more pressure. During an emergency stop, the valve prevents the rear brakes from activating before the front brakes. That is why the proportioning valve is valuable because it has the job of distributing pressure to the caliper.
Common issues with a faulty brake proportional valveA faulty brake proportional valve can cause the rear wheels to lock, and skid and the rear brakes will wear out faster.
