How It Works

The flow rate through an orifice is proportional to the size of the restriction and the differential pressure across it. Regardless of upstream or downstream pressure fluctuations, the internal regulating valve will maintain a constant pressure drop across the adjustable orifice to deliver the set flow rate. In gas applications, variations in upstream pressure and temperature should be minimized due to the compressibility of gases and the corresponding changes in density.

P1=P2 + Spring Force

For example; if supply pressure (P1) increases, the resulting momentary pressure imbalance immediately moves the impeller downward. This action restricts the valve ports thus increasing orifice backpressure (P2), restoring differential pressure and the flow rate to the original settings. The unit will respond equally as well to an upset in outlet pressure (P3).
