Valve cavitation pressure and critical pressure?
Thread Content
Seeking help: The manufacturer of the steam control valve requires information on the critical pressure and cavitation pressure of this steam valve I would like to ask fellow users how to input these two parameters and how to calculate them. Thank you
Same question, please ask the expert.
Dear OP, if you manage to solve it, could you also teach me?
These are two physical parameters of the process medium, not parameters of the valve; for example, the critical pressure of water is 22.12 MPa. Cavitation pressure should refer to the saturated vapor pressure, which is related to temperature; for example, water has a certain saturated vapor pressure at a specific temperature. These two parameters are required when selecting a control valve.
This control valve manufacturer should be easy to find!
There is a standard for this; I’ve forgotten on what it’s based, but it’s the critical pressure
