ABSTRACT:
A valve actuator is provided for use with a valve having an actuator shaft the rotation of which actuates the valve. The valve actuator comprises a housing having a worm gear rotatably mounted in the housing and wherein the worm gear includes a shaft portion extending externally of the housing so that a handle may be secured thereto. A segmented gear having an axis of rotation generally perpendicular to the worm gear axis, is also rotatably mounted within the housing and is positioned to mesh with the worm gear so that rotation of the worm gear produces a like rotation of the segmented gear. The segmented gear includes means for securing the actuator shaft thereto and an indicator is secured to the segmented gear and is visible exteriorly of the housing to indicate the rotational position of the segmented gear to thereby indicate the degree of opening of the valve. In addition, preferably adjustable stop members are provided in the housing to limit the rotational travel of the segmented gear.
