These fluctuations in pressure, within a given pressure differential control range, do not change the flow through the valve, therefore the flow is controlled to within +/- 5% of the designed flow. Valves may also be automatic, driven by changes in pressure, temperature, or flow. The automatic flow balancing valve is actually a constant flow valve that keeps the flow constant. The cartridge absorbs pressure that is often caused by changes in flow conditions, and the control valve regulates these fluctuations. ...regulate the flow or pressure of a fluid.
