problem w/ TCV during transient analysis
Rodman Houser
i defined an operational pattern for a TCV to simulate gradual valve throttling, but the transient model yields unexpected results. The pattern starts at 0% relative closure and gradually (in one second intervals) ramps closed (in 10% increments), so…

Control valve response to transient event
LWillnow
Is there a way to model the response of a control valve to a transient event beyond manually inputting the transient operational pattern? An example would be what happens to a PSV when the transient pressure drops below the pressure set point.

Re: Modelling with TCV
Jesse Dringoli
Sovan, The table you mentioned defines the valve characteristics, not the closure pattern. Be sure to also define the operating rule, which is the pattern of closure over time. You can also find some advice on modeling TCV closure here: …
