A pneumatic ball valve is a type of valve that uses compressed air to actuate (open or close) a ball valve. It's commonly used in industrial automation systems where quick, reliable, and remote-controlled flow regulation of liquids or gases is needed.

A pneumatic butterfly valve is a quarter-turn valve used to regulate or isolate flow, operated by a pneumatic actuator. It’s especially suited for handling large volumes of fluids or gases in systems where quick and frequent operation is needed.
