DescriptionDescription
Brooks® flow controllers are designed to maintain a constant differential pressure across
an integral manual flow regulating valve. The incoming fluid pressure on one side of the
diaphragm, and outlet pressure plus spring action on the other side, position an integral
diaphragm-actuated control valve. Variations in the supply or discharge pressure disturb
the balance of forces on the diaphragm, causing the internal control valve to open or
close, thus maintaining a fixed differential pressure across the integral, manual flow
regulating valve resulting in constant flow. (Refer to Figure 1)
