Use the Valve node to introduce additional pressure losses due to irreversible turbulent friction in a point associated with the position of a valve in the pipe system. Select a predefined valve type or provide a user-defined loss coefficient.

Select a Valve—Globe valve (K = 10) (the default), Angle valve (K = 4.4), Gate valve (K = 0.2), Ball valve (K = 4.5), Butterfly valve (K = 0.6), Swing check (K = 2.5), or User-defined loss coefficient. For User-defined loss coefficient enter a Loss coefficient Kf (dimensionless).
