The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch … WebA K v value is defined as the rate of flow of water in m 3 /hr and 4°C at a pressure drop of 1 bar across the equipment. K v relates to pressure drop and flow rate via the following expression: \displaystyle K_v = Q \sqrt { \frac {SG} { \Delta P}} K v = Q ΔP SG. Where Q is in m 3 /hr and ΔP is in bar. Thus for a given K v, ρ and Q the ...

WebValve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop …

WebValve Flow Calculations. Valve coefficient (Cv) is a number which represents a valve's ability to pass flow. The bigger the Cv, the more flow a valve can pass with a given pressure drop. A Cv of 1 means a valve will pass 1 gallon per minute (gpm) of 60 o F water with a pressure drop (dp) of 1 PSI across the valve. paragon video game trailersWebEach valve will have a Cv rating, which represents the quantity of room temperature water that will flow (in GPM) through the valve with a 1 PSI pressure differential.
