How does a hydraulic proportional valve work
A proportioning valve is a valve that relies on the laws of fluid pressure to distribute input forces to one or more output lines. A proportioning valve can increase or decrease forces for each output, depending on the cross-sectional surface areas of those output lines. A simple example is an input tube with cross-sectional area A entering a cham… WebJun 8, 2009 · The proportional throttle valve in Figure 14-12 meters flow out of the tank line of a standard solenoid valve.
