Abstract
A flow-actuated valve for use in a wellbore includes: a body; a poppet movable relative to the body between an open position and a closed position; a spring biasing the poppet toward the closed position; and a shifter having a drogue and a detent engaged with a detent profile of the poppet and a locking receptacle of the body when in an auto-fill mode, thereby keeping the poppet in a partially open position. The valve is operable to shift to a float mode in response to a first flow rate moving the poppet toward the open position to disengage the detent from the locking receptacle and a second flow rate imparting a drag force on the drogue sufficient to disengage the detent from the detent profile. The second flow rate is different than the first flow rate.
