The Brooks 8744 / 8800 / 8900 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.
The Model FC 8744 controllers are used for accurately adjusting and maintaining small gas and liquid flows with variable downstream pressures.
The FC 8800 Series controllers are used for accurately adjusting and maintaining liquid and gas flows with variable upstream pressures.
The FC 8900 Series controllers are used for accurately adjusting and maintaining liquid and gas flows with variable downstream pressures.
Applications for the 8744 / 8800 / 8900 Flow Controllers include:
- Pharmaceutical production
- Oil and gas pumping and refining processes
- Fuel cell research
- Chemical manufacturing
- Analytical instrumentation
- Water treatment and distribution systems
