An actuation system () is provided. The actuation system () includes a fluid operated actuator () and a control valve (). The control valve () is movable between a first position and a second position and is adapted to open a fluid flow path from a pressurized fluid supply () to the actuator () when the control valve () is in the first position. A diverting fluid conduit () is provided that is adapted to divert a portion of the pressurized fluid supplied to the actuator () when the control valve () is in the first position. The pressurized fluid diverted through fluid conduit () biases the control valve () towards a second position.
