Abstract

For use in a fluid flow system, a ball valve having two operative positions, namely the open and the closed positions, is operated by an electric motor which is under the control of an electric control circuit. This control circuit comprises a control switching means capable of taking two different states, at one of which the motor is energized to drive the valve toward the open position. The motor is de-energized by positioning switch means which is changed over to open the current supply path to the motor, when the valve reaches the open position. At the same time with this changing-over of the positioning switch means, another current supply path to the motor is previously provided, which path can thereafter be closed by setting the control switching means to the other state, to thereby rotate the valve to the closed position. In this manner, the opening and the closing operations of the valve can selectively be controlled merely by changing over the control switching means.
