Abstract
A valve has a housing, a valve spindle projecting outward from the housing and centered on and rotatable about an axis, and an actuating handle. Radially inwardly projecting and axially extending ridges are formed in the handle. An overload protecting coupling is formed by a sleeve fitted over the spindle and formed unitarily with a skirt having an inner surface spaced radially outward from the spindle and an outer surface formed with radially outwardly projecting and axially extending ridges meshing with the ridges of the handle. The skirt is formed with a plurality of axially inwardly open slots subdividing it into a plurality of ridged segments and it is elastically inwardly deflectable. Thus this sleeve forms a slip coupling that allows the handle to rotate the valve spindle until same is arrested, for instance at the end of its stroke, and thereafter turn independently of the spindle to prevent overloading it.
