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.

Overview
This technote explains…
I am attempting to set up a model to demonstrate how a RPZ (Reduced Pressure Principle Backflow Preventer) will respond to Hammer.
For those unfamiliar with the operation of an RPZ, I have attached a document which outlines this very well.

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.
Hello,
The pumps are going to operate based on the system conditions (where the pump curve intersects the system head curve.) So, you'll need to "model what you've got" to get the right pump operating point. Meaning, if there aren't FCVs in reality…
