Calculate flowrates, valve flow coefficients and pressure drops for saturated steam applications.

Please Note:

'This sizing calculator is empirical and is better suited to self-acting valves and non-critical applications for globe type control valves up to DN80 (3"nominal bore).

For control valves with pneumatic or electric actuators sized to a recognised standard, such as IEC 60534, please contact Spirax Sarco'.

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