Description

PressureReducingValve-States

This model describes a pressure reducing valve with lumped volumes. Pressure reducing valves have the purpose to provide a constant pressure (p_nom), independent of the upstreamstream pressure. They are used to limit the pressure of a primary circuit to a desired pressure for a secondary circuit.
