Actuating handle assembly

摘要

A handle assembly mountable on a valve is disclosed. The assembly includes a head having a receptacle engageable with a rotatable shaft on the valve and a grip projecting outwardly from the head to facilitate turning of the head for actuating the valve. An arcuate slot is positioned in the head, the slot having a curvature matched to the arcuate motion of the handle when used to turn the valve shaft. A limit post is attached to the valve and projects through the slot. A jam nut is mounted on the post adjacent to the head. When tightened against the head the jam nut fixes the position of the head relatively to the valve. A bolt is positioned within the slot and retained by a nut. The bolt is movable along the slot to a predetermined position where it can be temporarily fixed by tightening the nut. The bolt acts as a memory stop when it engages the limit post as the head is turned.
