3. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   A back-pressure regulator, back-pressure valve, pressure sustaining valve or pressure sustaining regulator is a control valve that maintains the set pressure at its inlet side by opening to allow flow when the inlet pressure exceeds the set value. It differs from an over-pressure relief valve in that the over-pressure valve is only intended to ...

4. Diving regulator - Wikipedia

   en.wikipedia.org/wiki/Diving_regulator

   A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.

5. Flow coefficient - Wikipedia

   en.wikipedia.org/wiki/Flow_coefficient

   The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as. where. ΔP is the ...

6. Centrifugal governor - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_governor

   Centrifugal governors, also known as "centrifugal regulators" and "fly-ball governors", were invented by Christiaan Huygens and used to regulate the distance and pressure between millstones in windmills in the 17th century. [1][2] In 1788, James Watt adapted one to control his steam engine where it regulates the admission of steam into the ...
