Methods, apparatus, systems, and articles of manufacture are disclosed to control propeller pitch in dual acting propellers. An example propeller control system comprising: a piston including a piston rod; a first valve connected to the piston rod via a first piston line and a second piston line, wherein the first valve selectively allows, based on an input signal, hydraulic fluid to transfer to the piston via the first piston line and the second piston line, wherein the first valve is a three-state valve; and an independent valve connected to the piston rod via a third piston line, wherein the independent valve selectively allows, based on an input signal, hydraulic fluid to transfer to the piston via the third piston line and wherein the independent valve operates independently of the first valve.
