Control Valve Cv Chart. The valve flow coefficient, cv, is the number of u.s. Common control valve and instrumentation terminology.
A valve cv can be described as the number of gallons per minute (gpm) at 60 o f (15.5 o c) that will pass through a valve with an associated pressure drop of 1 psi. The valve flow coefficient (c v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters.the c v calculator will calculate either c v or flow using the supplied additional parameters of fluid, inlet and outlet. These workbooks include typical valve sizing and noise calculation parameters and typical tables of valve capacity (cv) for a number of the.
Having selected the basic valve design, consult the
Download water c v diagram ; The speed of sound in steam will depend upon the steam temperature and the quality of the steam, but can be calculated from equation 6.4.2 if the conditions are known (mach. These general service applications include process events such as erosion, abrasion, corrosion, cavitation, and flashing found in most process control industries. If this new c v is smaller than small valve c v, use small valve size.
