ABSTRACT:
A unitary handle structure to be secured to the shaft of the valve and cooperate with the stops on the body to delimit and lock the valve element in its open and closed positions. The handle structure includes a socket portion fixed to the stem of the valve element and a handle portion extending from the socket portion and doubling back towards the socket portion and terminating at an end adjacent the socket portion. A detent portion on the end includes a pair of walls sufficiently spaced to receive the stops to lock the valve element in the open and closed positions. The handle portion is flexibly resilient to allow the detent portion to raise and lower with respect to the stops. One of the walls of the detent has a height high enough and the end of the handle portion is separated from the adjacent portion of the handle by a sufficiently short distance to prevent the one wall of the detent portion from raising above the stops.
