A system for controlling propeller pitch in the event of electro-hydraulic servo valve (EHSV) failure can include an actuator and a selection valve in fluid communication with the actuator. The selection valve can be fluid communication with a first EHSV having a first null state bias configured to bias the actuator to an increased-pitch position, and a second EHSV having a second null state bias configured to bias the actuator to a decreased-pitch position. The selection valve can be configured to selectively allow fluid communication between one of the first EHSV and actuator and/or the second EHSV and the actuator.
