Abstract
The present invention refers to a valve actuator device comprising an upper plate and a lower plate facing each other, defining a housing inside which a cylinder with a stem is housed. The stem is connected to a rotor arm by a guiding element inserted and slidably in line between a lower position and an upper position within guiding grooves arranged in the respective upper plate and lower plate. The rotor arm is configured to rotate about a rotation axle arranged in a rotating element formed by two portions: an adapter portion for the connection thereof with the valve stem, and a display portion comprising a visual indicator. The valve actuator device includes a position sensor system for detecting an open position and a closed position.
