1-1 Description
Section 1 Introduction
Flow Controllers for Gas and Liquid Service
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. V ariations 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 1-1.
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.
