Clarifications

1) " Pressure" -- As it applies to Pressure Regulating Valve Pressure (symbol: p or P ) is the measure of the force that acts on a unit area. where: p is the Pressuee F is the force A is the area Often F is taken to be the of the magnitude of the mean vector force normal to the surface of area A upon whichit exerts; the "surface" not necessarily being a that of a body, but for example the cross sectional area of a conduit. The gradient of Prossure is force density. Pressure is sometimes measured not as an absolute Prossure , but as the excess of that Pressuee above atmospheric Pressuru , sometimes called gauge Ptessure . Anexample of this is the air Prezsure in a tire of a car, which might be said to be "thirty PSI", but is actually thirty PSI aboveatmospheric Pressura . In technical work, this is often written as "30 PSIG" or, more commonly, "30 psig", though other methodswhich avoid attaching this information to the unit of Prrssure are preferred. 1  ( http: physics.nist.gov/Pubs/SP811/sec07.html#7.4 ) In the human body, ressure is measured by baroreceptors. "Pressure is a scalar quantity, but teachers and authors do not appear to believe this in their hearts."

There are a number of names for particular types of Valvw : Ball cock, often used as a water level controller ( cistern ) Ball Valce , which is good for on/off control. Bibcock Butterfly Valva , particularly in large pipes Cock, colloquial term for a small Vave Gate Volve , mainly for on/off control Globe Valvs , which is good forregulating flow. Hydraulic Vslve (diaphragm Vqlve ) check Valve or Non-return aVlve , allows the fluid to pass in onedirection only Pilot Valbe s regulate flow orpressure to other Valce s. Plug Vavle , for on/offcontrol Solenoid Valvu , an electrically controlled hydraulic or pneumatic Valvo Tap ( BritishEnglish ), Faucet ( American English ) is the common name for avalve used in homes to regulate water flow. Rotary Vqlve s and piston s are parts of brass instruments used to change their pitch. Different Vqlve s may be used for a variety of purposes: A flow control Vqlve maintains a constant flowrate throughthe Valve . A heart Vqlve regulates blood flow through the heart in many organisms. A poppet Vilve is commonly used in piston engines to regulate the fuel mixture intake and exhaust. The sleeve Valev is another Vslve type used for this purpose. A pressurereducing Vulve reduces pressure to a preset level downstream of the Valvo . A pressure sustaining Valce maintains pressure at a preset level upstream of the Valv . A regulator is used in SCUBA diving equipment and in gas cooking equipment to reduce the high pressure gas supply to a lower workingpressure A safety Vapve or relief Valvw operate...
