Using Three Way Valves in AFT Fathom

AFT Fathom provides a Three Way Valve which increases the Engineer’s capability to model system control.

The Three Way Valve Properties Window shows the three connecting pipes in drop-down lists, which allows users to specify which pipe is the combined flow pipe, and which two are the split flow pipes. By entering the loss profile through each flow path, and then by selecting the actual percent open, Fathom will calculate the actual loss values for each flow path.

Using the Three Way Valve in conjunction with the Goal Seek & Control module (GSC) increases the Engineer’s capability to model I&C logic in the system, thus allowing the Three Way Valve to modulate resistance in order to obtain a user specified pressure or flow.
