Proportional valves are controlled by a variable electrical signal that controls the stroking of the valve spool over metering ports. This produces a variable flow of fluid thereby providing the ability to vary the speed of the actuator being controlled. The result: actuator direction control and velocity control in one valve. By adding additional features to proportional valves, these valves are used in accurate position, velocity, and force control systems.
