Which valve on a spray gun adjusts how much paint flows through the nozzle when the trigger is pulled?

The fluid control valve is the part that meters how much paint actually flows through the nozzle when you pull the trigger. It sits in the fluid path and, by turning its adjustment or screw, you open or close the passage around the needle. Opening it more lets more paint through; closing it reduces the flow. This directly sets the volume of material that reaches the nozzle, shaping how dense or light your coating will be. The air cap affects how the paint atomizes and the spray pattern, the nozzle size determines the size of the spray orifice, and the trigger simply actuates the needle. But it’s the fluid control valve that controls the amount of paint delivered.
