Abstract: A fluid actuated control device for operable connection with a hydraulic valve, such as a pilot valve, and comprising a coupler bolt secured directly to the valve spool, a fluid actuated cylinder and piston assembly connected with the coupler bolt for reciprocation thereof, a helical spring member disposed around at least a portion of the coupler bolt and cooperating with a pair of oppositely disposed spring retainer cups for maintaining a normal neutral position for the valve spool, the coupler bolt being reciprocal by the fluid actuated cylinder and piston assembly upon the application of fluid pressure to the assembly for shifting of the valve spool from a remote position without interference with the normal manual operation of the valve.
