of the valve and slide the valve shaft into the hole on the worm
gear. Tighten the flange bolt. The valve can be closed by turning
the hand-wheel clockwise and opened by turning the hand-wheel
counterclockwise. On the upper face of the gear operator, a
position indicator and a position marking are mounted, through
which the position of switch can be directly observed. The gear
operator is also equipped with a mechanical limit screw, which can
be adjusted and function to limit the position at the switch
extreme position.
