SINGLE ACTING PNEUMATIC ACTUATED BALL VALVE.
A single-acting pneumatic cylinder actuated ball valve is a valve system that uses compressed air to control fluid flow through a ball valve, with actuation handled by a single-acting pneumatic actuator (typically a spring-return type). Here's a breakdown:

Components:

1. Ball Valve – A valve with a spherical disc (the ball) that rotates to open or close the flow.
2. Single-Acting Pneumatic Actuator – Uses air pressure to move the valve in one direction (usually open), and a spring to return it to the original position (usually closed) when the air is vented.
How It Works:

Air Supplied: The actuator receives compressed air, pushing a piston that rotates the valve stem and opens (or closes) the ball valve.

Air Removed: When air is vented, the spring inside the actuator returns the piston to its default position, closing (or opening) the valve.
Applications:

Fail-safe operations: For instance, automatically closing a valve in case of power/air loss.

Used in process industries for automation where safety and reliability are key.
