Do Pressure Regulators Restrict Flow

Pressure regulators are not designed to control flow rates. Although pressure regulators used in flowing systems inherently affect the flow by controlling the pressure, they are not designed to act as flow controllers.

What is the difference between a flow regulator and a pressure regulator?

The flow control valves are used for controlling and adjusting the fluid or gas flow through the system. The pressure control valve is used to regulate the pressure of a fluid passing through the pipe. The difference is exactly how it sounds.

What does a pressure regulator do?

Pressure regulators reduce a supply (or inlet) pressure to a lower outlet pressure and work to maintain this outlet pressure despite fluctuations in the inlet pressure.
