A system for filing or discharging compressed gas or liquid cylinders mounted on the cylinder. An automatic system for filing or discharging a compressed gas cylinder, specifically chlorine, sulfur dioxide, or ammonia cylinders. The system includes an electric motor that rotates the cylinder valve system toward open or closed position without interfering with or requiring additional adapters for the filing or discharge hardware. The motor, gears, and controls are assembled as one unit to eliminate the necessity for a separate control panel or interconnecting control wires. The system has the capabilities for integral leak detection with automatic shutdown, battery backup in the event of power failure, remote control by leak detector, remote control panic button, remote low weight transmitter, remote vacuum switch for automatic switch-over systems and other remote digital signals. The system requires only a flexible power cord for trickle charge of the battery backup, which makes the assembly totally portable when not in use. Placement of the system container can be accomplished by connection to the cylinder valve, a permanent stand, or a movable stand on casters. Motor and controls are accomplished through an on-board microprocessor with integral LED displays for "CLOSED," "ALIGN," and "OPEN" indicators. Programming is accomplished through an integral keypad. Actual valve position is transmitted to the microprocessor from a direct-coupled potentiometer.

[ What is claimed is:] [28.]28. A method for automatically rotating a valve stem with an actuator that is removably installed on the valve of a cylinder wherein the valve already has a device, for preventing certain hazardous conditions, selected from the group consisting of a Vacuum regulator; an ejector; a flow meter; a rate valve; and any other actuator, actuator component, chlorinator or combination thereof comprising the steps of:installing an actuator to the valve stem of the valve; andoperating the actuator.
