Abstract
Pneumatic actuator for valves, of the double-acting type, suitable for remote operation of ball or butterfly valves, preferably in a fluid line, characterized in that it is constituted by a pneumatic cylinder (1) inside which is a plunger formed by two discs (2) preferably, integral with each other by a cylindrical body (3) having two helical grooves (4) opposite in their contour, said cylindrical body (3) having a coaxial main shaft (5), emerging from the center of both discs (2) and fixed to the front (6) and rear (7) caps of the pneumatic cylinder (1), said main shaft (5) having a transverse through hole (8) at an intermediate point of its length, between two discs (2), finding in said hole (8) a transverse rod (9), whose ends are housed respectively in each of the helical grooves (4), because between the two helical grooves (4) ) is one or two straight longitudinal grooves (10) in which is the head or end of a lug (11) or fixed pivot in the inner wall of the pneumatic cylinder (1) and which is able to limit the longitudinal movement of the set of discs and cylindrical body (2,3); because the transverse rod (9) housed in the hole (8) of the main shaft (5) has at its two respective ends cap (12) derozamiento, subject with lock washers (15), and said helical grooves (4) are suitable to transmit to said transverse rod (9) a rotational movement angular with respect to the longitudinal axis of the actuator; in that the covers (6, 7) of the pneumatic cylinder (1) have one or more sealing gaskets (13) with the main shaft (5) and are capable of allowing only the rotational movement of said main shaft (s) i because said axis main (5) emerges through a cover (6) at one end (14) able to relate to stops, limit switches, contacts or other, existing in the lower cover (7) a standard housing to receive an intermediate part of coupling to the shaft from valvule.
