2. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   Two-gauge pressure regulator connected to gas cylinder used for breathing gas supply. Pressure regulators are used with diving cylinders for Scuba diving. The tank may contain pressures in excess of 3,000 pounds per square inch (210 bar), which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled ...

3. List of valves - Wikipedia

   en.wikipedia.org/wiki/List_of_valves

   Security valve, a type of automatic shut-off valve (ASV): used to stop the flow of natural gas upon sudden pressure changes. Increased pressure or decreased pressure closes the valve (without using any external power sources).

4. Relief valve - Wikipedia

   A relief valve DN25 on cooling water pipe from heat exchanger Schematic diagram of a conventional spring-loaded pressure relief valve. A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.

5. Valve - Wikipedia

   en.wikipedia.org/wiki/Valve

   Pressure regulators are variations of valves in which flow is controlled to produce a certain downstream pressure, if possible. They are often used to control flow of gas from a gas cylinder. A back-pressure regulator is a variation of a valve in which flow is controlled to maintain a certain upstream pressure, if possible.

6. Gas cylinder - Wikipedia

   en.wikipedia.org/wiki/Gas_cylinder

   When the gas in the cylinder is to be used at low pressure, the cap is taken off and a pressure-regulating assembly is attached to the stop valve. This attachment typically has a pressure regulator with upstream (inlet) and downstream (outlet) pressure gauges and a further downstream needle valve and outlet connection.
