A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.

For breathable air applications such as SCBA, these may found on both sides of the first-stage and second-stage pressure regulators (very similar to SCUBA diving regulators) to allow for rapid and tool-free return-to-service. [1]
Should this article be merged with Pressure reducing valve? Biscuittin 08:20, 17 August 2007 (UTC) Opening definition "A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure." is wrong! (that describes a check-valve). It does nothing of the sort. Pressure regulators do not control flow.
The compressed air lines will be piped from the compressor to one or multiple point of use outlets. At the outlet of a fixed air line you will typically find a Pressure regulator installed upstream of the termination/outlet point, this allows the user to regulate the pressure and flow of air to suit the desired use. The regulator allows each ...
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.
