| On closer examination of the inner workings of the FlowCon SM, the function is best described as 2 valves in 1. The first valve regulates the pressure differential across the second valve by means of a rolling diaphragm element counter acted by a helical spring. The second valve is a calibrated variable orifice device adjusted by the actuator (similar to a standard modulating control valve). The diaphragm reacts to the system and regulates the pressure differential across the actuated control valve orifice to maintain its flow rate within +/-5%.
