The Two-Way Two-Position Valve component allows flow between ports A and P with two positions to control the flow.
The real input controls the position of the value. An input of 0 corresponds to position 0, an input of 1 to position 1. Intermediates values produce an averaged position, with the transition length set by the parameter.
The following figure shows how and effect the valve opening.

Formulation Approaches

|
One of two approaches can be selected for modeling the flow in the device. When the boolean parameter is true, a constant coefficient of discharge () is used, otherwise a variable coefficient of discharge with maximum value () and a critical flow number () are used.
