A proportioning valve is a valve that relies on the statics to supply a reduced pressure to an output line.
A simple example is where spring load applies a reducing force so that the output pressure is reduced. Proportioning valves are frequently used in cars to reduce the brake fluid pressure to the rear brakes.
we have post compensation proportional valve, we can offer solutions to your hydraulic system.
