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.
The Valve can only be applied to a point which is connected to exactly two edges.
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), User-defined loss coefficient, or User-defined pressure drop. For User-defined loss coefficient enter a Loss coefficientKf (dimensionless). For User-defined pressure drop enter a Pressure drop (SI unit: Pa).
