Valve Cv Calculator Steam. The formula will differ depending on the product the valve regulates, such as liquid, gas, or steam. Flow coefficient, cv, and flow factor, kv, are values used to specify the hydraulic capacity of a control valve.
The flow coefficient for superheated steam ought to be multiplied with a correction variable. Hass manufacturing company accepts no responsibility for the acceptability or fitness of use. Online calculator to quickly determine valve and orifice cv & kvs values for steam.
Calculate flowrates, valve flow coefficients and pressure drops for saturated steam applications.
Saturated steam flow through a control valve. We recommend you select a valve for which the cv falls between 20% and 80% open stem travel. This might be useful if valve cv calculations need to be made at several flow rates, when only p1 and p2 are known at the maximum and minimum design flow rates. The saturated steam valve sizing calculator provides a simple calculation system for determining valve conditions.
