WebFlow Control valves maintain a fixed, pre-set, constant flow rate regardless of pressure*. This means a constant flow rate, irrespective of fluctuating pressures upstream or downstream of the valve. Flow Control valves are simple with no external actuation. They are self-regulating, self-cleaning, tamper-proof, long-life (15+ years) and reliable. WebThe accuracy of a pressure regulator is determined by charting outlet pressure versus flow rate. The resulting graph shows the drop in outlet pressure as the flow rate increases. This phenomenon is known as droop. Pressure regulator accuracy is defined as how much droop the device exhibits over a range of flows; less droop equals greater accuracy.
