Spring-Loaded check valve
The Check Valve component allows fluid flow in one direction, from port A to port B. The flow is controlled by an adjustable orifice whose area is controlled by the pressure difference from port A to port B.
The area increases linearly from Aclose to Aopen as the pressure increases from pclose to popen.
The pressure drop vs flow-rate, for the computed area, comes from the Orifice model.
The boolean parameters Use volume A and Use volume B, when true, add optional volumes VA and VB to ports A and B, respectively. See Port Volumes for details.
If two orifices or valves are connected, enabling a volume at the common port reduces the the stiffness of the system and improves the solvability.

When false (not checked) a first-order dynamics is used for the valve area
