Narrative:
Flight was cleared for takeoff on runway 18R from [a] taxiway. Once the aircraft was lined up on the centerline the propellers were set to 'speeds high.' when power levers were advanced there was no torque noted on the left engine. It seemed as though the left propeller was still on the 'start locks' so I brought the power levers back and brought the left power lever into beta to release the propeller from the locks. Advanced the power levers again and still no torque was noted. Attempted to release the propeller one more time. When again no torque was noted I advised tower that we were aborting the take off and needed to return to our ramp.maintenance determined that a feathering valve was stuck and would not allow the propeller to come off of the locks.
