2. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   They differ from pressure reducing regulators in that the pressure reducing regulator controls downstream pressure and is insensitive to upstream pressure. [2] It is a normally-closed valve which may be installed in parallel with sensitive equipment or after the sensitive equipment to provide an obstruction to flow and thereby maintain upstream ...

3. Diving regulator - Wikipedia

   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.

   A Dräger two-stage twin-hose regulator Beuchat "Souplair" single stage twin hose regulator Twin 7l cylinders with Draeger harness, valves, manifold and regulator from c. 1965 Duckbill exhaust valve for Draeger twin hose regulator. The "twin", "double" or "two" hose configuration of scuba demand valve was the first in general use. [16]

   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 ...

   They are often seen in drainage or sewage systems but may also be used in pressurized systems. Valves are available in several types, based on design and purpose: Gate, plug, or ball valves – Isolation; Globe valve – Throttling; Needle valve – Throttling, usually with high precision but low flow

   downstream valve. See: Diving regulator#Upstream vs downstream. Valve in which the closure is downstream of the orifice. Pressure in the line tends to assist in opening the valve. When spring-loaded a downstream valve may open automatically if the pressure difference is excessive, thus functioning as a pressure relief valve down time
