[ What is claimed is:] [1.] An integrated valve control and monitoring assembly for indicating the open and closed positions of a driven valve, said assembly being associated with a rotary actuator for said driven valve, comprising:a targeting device mounted to an auxiliary shaft extending from said rotary actuator for providing immediate visual indication as to the position of said driven valve;a control housing secured to said rotary actuator and positioned alongside said targeting device, thereby transverse to the auxiliary shaft of said rotary actuator;a pneumatic valve secured to an outer surface of said control housing for controlling a supply of air to said rotary actuator for opening or closing said driven valve; anda solenoid positioned within said control housing for activating said pneumatic valve. [2.] An integrated valve control and monitoring assembly as recited in claim 1, wherein said targeting device comprises:a common shaft secured to and extending from the auxiliary shaft of said rotary actuator and terminating at a distal end thereof, said common shaft rotating with the auxiliary shaft of said rotary actuator;a lower target mounted on said common shaft, said lower target being appropriately keyed to rotate with the common shaft; andan upper target mounted on said common shaft above said lower target, and having an indicia on an external surface thereof for providing immediate visual indication of the position of the upper target relative to a predetermined reference point, said upper target being selectively and adjustably secured to said lower target for rotation therewith, the angular position of said upper target relative to said lower being selected to correspond to the rotation of the driven valve from a fully open position to a fully closed position. [3.] An integrated valve control and monitoring assembly as recited in claim 2, wherein said targeting device further comprises a pointer that is mounted on said common shaft at the distal end thereof, said pointer being appropriately keyed to rotate with the common shaft and said lower target.
