ABSTRACT:
A fluid powered valve actuator is disclosed for a valve having a valve body and a threaded valve stem for connecting to the actuator to be reciprocated along its longitudinal axis to open and close the valve. The actuator includes an actuator housing for attaching to the valve body, a fluid motor mounted on the housing having a cylinder, a piston in the cylinder, and a piston rod having one end attached to the piston. To connect the valve stem to the piston rod, a connecting block having a threaded opening in one end is screwed onto the threads on the valve stem. An opening in the other end of the block receives the end of the piston rod. There are grooves extending transverse the longitudinal axes of the piston rod on opposite sides of the piston rod and grooves in the connecting block on opposite sides of the opening in the block, and openings in the connecting block through which rods can be positioned, with each rod in engagement with a groove in the block and a groove in the rod to connect the connecting block to the piston rod. The piston rod is of tubular construction to allow the valve stem to extend into the rod if required to adjust the stroke of the rod to the valve.
