Abstract: A method and apparatus for actuating rotating valves with fast closing times, high precision, and high force. The invention incorporates a lever arm attached to the valve shaft, accompanied by a housing for one or more cylinder-type linear actuators. A pivot mechanism allows the actuators to comply with movement. Multiple actuators can be attached to the lever arm's shaft, which pivots smoothly with the aid of a bearing. The housing securely bolts to the valve mounting flange, ensuring stability and alignment. A front guard with a position indicator window covers the lever arm, while a rear guard protects the actuators. By enabling longer and shorter strokes than the open and closed positions, multiple actuators can be precisely programmed and synchronized for optimal performance. This approach potentially improves valve actuation, offering enhanced speed, precision, and force for diverse fluid or slurry flow control applications.
