Which component would you adjust to direct flow or shut off the spray during operation?

• A. Tank
• B. Nozzles
• C. Valves
• D. Strainers

Answer: (C)

Directing flow and stopping spray during operation is handled by valves. Valves are the components you open or close to let liquid pass or to halt it, and they can also redirect flow to different paths if there are multiple lines. When you want to start spraying, you open the valve; to stop, you close it. If you need to divert flow or isolate a section for maintenance, you adjust the valve accordingly.

Tanks hold the chemical, not flow control. Nozzles set how the spray comes out (pattern, droplet size) but don’t turn the flow on or off. Strainers clean the fluid to protect the nozzle but don’t manage flow paths. So the valve is the component designed for directing flow and stopping spray.
