ABSTRACT:
A pedestal extends upwardly from the body of a gate valve housing in a straddling relationship to the gate. An operator, detachably attachable to the pedestal, includes a hand wheel operating through a pinion gear to impart translatory movement to a vertically oriented rack. A clevis is disposed at the lower extremity of the rack for attachment through a pin to the upper end of the gate. A removable pin is employed to secure the gate, in either a raised or a lowered position, to the pedestal and to maintain the gate in position after removal of the operator.
