Which term is described by the stop valve symbol?

Explanation:
A stop valve is an isolation device used to shut off flow in a pipeline. The symbol for this component indicates its function: to stop or allow flow as needed, typically controlled manually. It’s not depicting a backflow-preventing mechanism like a swing check valve, which would have a different symbol indicating a hinged disk. Nor does the symbol imply a locking feature unless an actual lock indicator is shown nearby. So the term described by the symbol is stop valve.
