Description

The component PressureReducingValve is a model of a 2-port pressure control valve. It maintains a largely constant outlet pressure even at a variable (higher) inlet pressure.

If inlet pressure pA is less than Set pressure (relative value) the valve acts like an orifice with the characteristics Nominal volume flow and Nominal pressure difference.

For all pressures exceeding Set pressure (relative value) the valve opens and the flow increases linearly following the slope given by parameters Nominal volume flow and Pressure drop.

The component PressureReducingValve is not a model of a pressure control valve according to its physical structure. It merely represents the characteristic behavior of a pressure reducing valve. Therefore dynamic effects such as forces due to inertia will not be represented.
