Sizing for Dry Saturated Steam

The Saturated Steam Valve Sizing calculator provides a simple calculation system for determining valve conditions. Calculate flowrates, valve flow coefficients and pressure drops for saturated steam applications.

The calculations have been used within Spirax Sarco for many years as a means of gaining a close approximation of the required value for the specified conditions.

This system is only for dry saturated steam and does not include wet or superheated steam.

For a more in-depth valve calculation the user should refer to the British Standard on Valve sizing (BS EN 60534-2-1:1999, IEC 60534-2-1:1998).

Note: - You cannot use commas (,) as decimal points. Please use periods (.)
Example: 1.02 not 1,02
