Model FC8744 / FC8800 / FC8900 Manual Flow Controller
Brand: Brooks Instrument.png)
Supply or discharge pressures may vary. But with flow controllers from Brooks Instrument, the differential pressure across the integral manual flow regulating valve remains constant.
An internal diaphragm-actuated control valve receives incoming pressure on one side and outlet pressure with spring action on the other. This design balances pressure variations to maintain a fixed differential pressure across the valve that ensures constant flow.
The result is precise flow control for many gas and liquid-service applications. Can be used as a stand alone flow controller or integrally mounted to a flow meter to save space and improve installation.
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.
