What is the main role of the sprayer pressure regulator?

• A. Controls pressure and, indirectly, quantity of spray material delivered by nozzles
• B. Filters contaminants from the spray
• C. Adjusts droplet size for all nozzles
• D. Stores auxiliary power for sprayer

Answer: (A)

Maintaining a constant spray system pressure is the main job of the sprayer pressure regulator. By holding the system at a specified pressure, it keeps the flow through each nozzle steady, so the spray rate and coverage (gallons per acre) stay predictable as you move or as conditions change. It doesn't filter out contaminants—that's what a filter does. It also isn’t responsible for directly setting droplet size across all nozzles; while pressure can influence droplet size, that’s mainly determined by the nozzle design and type. And it doesn’t store power. So the regulator’s core function is to control and maintain the set pressure, ensuring consistent application.
