The invention relates to a butterfly valve (24) for bleeding a compressor for an aircraft turbine engine, the valve including a valve body (32), a butterfly (36), and a device (42) for controlling the angular position of the butterfly, the device (42) including a mobile actuation member (64) connected to the butterfly by a link (70), the member (64) being subjected: to a first adjustable pressure force (F1) applied by air from the compressor, the first force (F1) returning the butterfly (36) to a closed position; and to a second mechanical force (F2) returning the butterfly (36) to an open position, and coming from an aerodynamic torque (C) applied by the air to the butterfly (36), of which the axis of rotation (38) is off-centre relative to the butterfly.
