Supplementary oxygen for high altitude flight in unpressurised aircraft and medical gases are also commonly dispensed through pressure reducing regulators from high-pressure storage. [ 6 ] [ 7 ] Supplementary oxygen may also be dispensed through a regulator which both reduces the pressure, and supplies the gas at a metered flow rate, to be ...
A scuba regulator first stage has one or two high pressure ports upstream of all pressure-reducing valves to monitor the gas pressure remaining in the diving cylinder, provided that the valve is open. The standard connection is an O-ring sealed 7/16" UNF inside thread. [1] There are several types of pressure gauge.
The first stage regulator body generally has several low-pressure outlets (ports) for second-stage regulators, BCD inflators and other equipment; and one or more high-pressure outlets, which allow a submersible pressure gauge (SPG), gas-integrated diving computer or remote wireless pressure transducer to measure the cylinder pressure.
Pressure regulator or pressure reducing valve (PRV): reduces pressure to a preset level downstream of the valve; Pressure sustaining valve, or back-pressure regulator: maintains pressure at a preset level upstream of the valve; Presta valve, Schrader valve, or Dunlop valve, holds the air inside bicycle tires; Pulse valve, extremely fast pulsing ...
A diving regulator is a device that reduces the high pressure in a diving cylinder or surface supply hose to the same pressure as the diver's surroundings. It is desirable that breathing from a regulator requires low effort even when supplying large amounts of breathing gas as this is commonly the limiting factor for underwater exertion, and ...
