Valve Closure example
Jesse Dringoli
This example model illustrates different ways to model valve closure with a TCV. Advanced TCV closure modeling is not included. Note: This model can be opened in HAMMER version 08.11.00.30 and above.

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.

Modeling pump startup against a closed valve in HAMMER
LWillnow
We are trying to model a pump startup scenario in HAMMER (v 8.11.03.17) with the pump starting 10 seconds into the simulation and the discharge valve starting to open up 15 seconds into the simulation. We followed the Tech Note for startup scenario but…

Modeling Valve closure in Hammer
suminda
Hi, I am modeling a HDPE treated water pumping main to see the effects of a pump trip and a valve closure (at the end). I am planning on using a altitue valve and it is supposed to close when the tank is full and also another motor operated valve to…
