This is a pneumatic actuator ball valve assembly, commonly used for automated flow control in industries like petrochemicals and water treatment.
The top component is a pneumatic actuator, likely a rack-and-pinion model, which uses air pressure to turn the valve.
The bottom component is a stainless steel ball valve attached to the actuator via a bracket.
The assembly is pictured with packaging film still attached, suggesting it is new or recently shipped. [1, 2, 3, 4, 5, 6]
