Watch this video to learn about considerations in design for minimizing droop in a pressure-reducing regulator. Typically, a flow curve for a pressure-reducing regulator consists of three parts: (1) a steep drop on the far left; (2) a relatively flat part in the middle; and (3) a steep drop on the far right. This typical flow curve for a pressure-reducing regulator illustrates several phenomena, including the ideal operating range, droop, choked flow, and seat-load drop or lockup.
