A valve actuator is provided which clamps to the axially extending assembly bolts of the valve or to ribs on the valve body simulating the bolts. The actuator has a support frame with ears which seat over a pair of the bolts or ribs and by means of stops formed by recesses in the ears seat the support frame on the bolts or ribs and threaded anchor members, when tightened, cause the ears to tightly clamp to the bolts or ribs, preventing either lateral or axial movement with respect to the valve body.

Means for securing an actuator to a valve, the valve having a body including a plurality of bolts arranged exteriorly of and in spaced relationship around the valve body and extending lengthwise thereof for holding the valve body together, said means comprising: a frame element for supporting the actuator, said frame element having a flange adapted to extend generally parallel to one side face of the valve body and having a pair of ears mounted thereon and spaced apart to seat on at least two of said bolts and against the outer faces thereof for supporting said frame element; said ears each having a step forming a stop surface facing away from said flange, said stops facing each other and seating on said bolts for limiting movement of said ears toward said valve body and stabilizing said ears and frame against rocking motion lengthwise of said bolts; anchor means on each of said ears movable for engaging the surface of said bolts opposite from said stops for locking said ears and frame element to said valve body.
