Which equipment allows for automatic or manual control to direct flow and maintain pressure?

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

Answer: (B)

Valves control where the liquid goes and how it’s pressurized in a spray system. They can be opened, closed, or throttled to route flow through different paths and to hold the system at a desired pressure. This control can be manual—you turn a handle or wheel—or automatic, using a solenoid, pilot, or pressure regulator that adjusts flow in response to changes in the system. That combination of directing flow and maintaining pressure is what makes valves the right answer. Tanks store the liquid but don’t regulate or direct flow. Nozzles determine the spray pattern and droplet size, not the system pressure, so they don’t provide flow control. Strainers remove debris to protect equipment, but they don’t manage flow or pressure either.
