Abstract
A valve actuator () includes an electric motor () that opens, and also closes if need be, the valve via a gearing (). A voltage supply device () has an input rectifier circuit and a buffer device () connected thereto, for example in the form of a capacitor C. From the voltage buffered by the capacitor C, a motor control circuit () obtains the energy for operating the electric motor (). To prevent the valve () from being kept open too long after the voltage supply at the input () has been switched off, a switch-off device () is provided, which, after elimination of the voltage at the input (), cuts off the energy flow from the voltage buffer device () to the electric motor ().
