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
Downstream steam pressure
Downstream critical steam pressure

Cv to Kv Converter

Input Kv


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
