WebHydraulic proportional control valves work in a similar way to directional valves except they do not switch from fully shut to fully open. Instead, they gradually open a restricted flow orifice area. The size of the orifice opening is proportional to the amount the spool moves, either controlled by an electrical solenoid or a hand lever. ... WebHow Proportional Valves Operate: An electrical input from some source is wired to an amplifier card, which in turn, controls a coil on the proportional valve. Since the electrical input from most sources is generally much lower in power than the amount of current required to operate the coil, the input current must be amplified. fnsb clerk officeWebSep 5, 2024 · Hydraulic valves can be used to control the flow of fluid in a circuit as well as the quantity of fluid power.
