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. The valve actuator device may include a position sensor system for detecting an open position and a closed position. The valve actuator device may include a manual override system for manually opening or closing the valve.
Claims5
A valve actuator device, comprising:
- an upper plate (1) and a lower plate (2) facing each other, defining a housing inside which a cylinder (3) with a stem (5) is housed,
- said stem (5) being connected to a rotor arm (7) by means of a guiding element inserted and slidably in line between a lower position and an upper position within guiding grooves (9, 9′) arranged in the respective upper plate (1) and lower plate (2),
- said rotor arm (7) is configured to rotate about a rotation axle (11) arranged in a rotating element (12′) adapted to be connected to a valve stem;
- an upper rotating element (35) configured to rotate with said rotor arm (7), said upper rotating element (35) being operatively connected to a manual override system (29), wherein said manual override system (29) comprises an annular body (30), a shaft (32) affixed to said annular body (30) and a handle (33) extending from said shaft (32), whereby turning of said handle (33) rotates said annular body and in turn rotates said upper rotating element (35), said rotor arm (7), and said rotation axle (11).
