stopcocks
Pipe flow regulators
Stopcocks are valves that control the flow of liquid or gas through a pipe.
Each stopcock has a handle or lever that opens, closes, or regulates passage through the line.
A main stopcock typically controls water supply to a building: Turn off the stopcock before replacing the faucet.
The term appears in plumbing, laboratory equipment, and industrial contexts.
