Which sprayer component is used to regulate pressure?

• A. Tank
• B. Hose
• C. Pressure regulator
• D. Nozzles

Answer: (C)

Maintaining a steady spray pressure is essential for uniform application. The pressure regulator is the component that does this. It senses the pressure downstream and adjusts a valve to keep the system at a set level, so the flow to the nozzles stays consistent even as you spray or as demand changes. That stability helps produce uniform droplets and coverage, improves efficiency, and protects the pump from pressure spikes.

The tank just holds the liquid, the hose is the conduit, and the nozzles shape and deliver the spray; they don’t actively regulate pressure. A relief valve might vent excess pressure, but the device specifically designed to maintain target pressure throughout the system is the regulator.
