BENEFITS
• Flow controllers for high pressure or low flow rates
to handle demanding applications
• Integral mounting to flowmeter to save space and
improve installation
• High-resolution valves provide precise flow control
for many applications
• Many different materials of construction that
provides process immunity and flexibility
DESCRIPTION
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 internal 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.
Model FC 8744 controllers are used for accurately
adjusting and maintaining small gas and liquid flows
with variable downstream pressures.
Series FC 8800 controllers are used for accurately
adjusting and maintaining liquid and gas flows with
variable upstream pressures.
Series FC 8900 controllers are used for accurately
adjusting and maintaining liquid and gas flows with
variable downstream pressures.
