Abstract
A valve operating apparatus with controls may include a speed control engageable by a hand of an operator of the apparatus to control a speed characteristic for operating the valve. The speed control may have a zero position corresponding to a zero speed of rotation of a shaft for connecting to the valve, with the speed control being movable out of the zero position to a nonzero position corresponding to a nonzero speed of rotation. A degree of movement of the speed control from the zero position may correspond to a speed of rotation of the shaft such that further movement of the control away from the zero position increases the speed of rotation. Movement of the speed control from the zero position may be characterized by the speed control maintaining the position of the speed control when engagement of the control by the hand of the operator is discontinued.
