Steam control valve, downstream pressure estimator
Use to estimate downstream steam pressure out of a steam control valve when; upstream steam pressure, steam flow, and the Kv of the valve are known
| Upstream steam pressure | ||
| Steam flow rate | ||
| Kv | ||
| Downstream steam pressure | ||
|---|---|---|
| Downstream critical steam pressure | ||
Cv to Kv Converter

Notes:
Figures calculated are of a simple theoretical nature and other variables may need to be considered depending on application
Estimates based on saturated steam
Assumes sub-sonic flow through the valve
