DATA SHEET Flow Controllers Model FC 8744, Series FC 8800 & FC 8900 Flow Controllers for Gas & 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 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) 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. 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 Product Specifications Flow Ranges (Refer to Table 1) Pressure and Temperature Ratings Minimum Operating Temperature: Maximum Operating Temprature: Water - up to 480 GPH / 1820 l/h Air - up to 2130 SCFH / 56000 ln/h Up to 1000 psig / 69 Bar. Refer to Table 2a or 2b -40°F/C Refer to Tables 2a or 2b. Pressure Drop Pressure Equipment Directive (97/23/EC) Refer to Table 2a. Equipment falls under Sound Engineering Practice (SEP) according to the directive. View Flow Controllers Product Page BrooksInstrument
