ABSTRACT:
An apparatus for actuating a valve includes a rotatable control shaft connected to the valve and a gearbox wheel is secured to the control shaft. A worm intermeshes with the gearteeth of the gearbox wheel such that when the worm is rotated, the wheel and the shaft are rotated for moving the valve between the open and the closed disposition thereof. A housing defines an enclosure for the reception therein of the gearbox wheel and the intermeshing worm. Bearings are slidably disposed within recesses so that location of the worm into intermeshing relationship with the gearteeth is facilitated. A multi-turn power drive is secured to the flange and is drivingly connected to the first extremity of the worm for rotating the worm so that the valve is controllably moved between the open and the closed disposition thereof.
