March 12, 2018. Measurement, Instrumentation, Control & Automation. Vary-P control valves were already introduced by Bronkhorst in 1985 for controlling high-pressure gas flow with high pressure differences of up to 400 bar (later on extended to 700 bar!). The control valves - usually integrated in a mass flow controller (F-230 series) - are

A mass flow controller (MFC) will typically measure the mass flow and adjust the valve to increase or decrease the mass flow to the setpoint. When controlling on pressure, the valve will instead adjust based on the pressure measurement. Imagine, for example, that you are controlling pressure downstream of the Alicat and want to reach 100 PSIA.
