FORMULATION:

The component calculates the speed of the valve opening according to parameters such as the range of the valve, the increase in speed set by the user and the pre-constraint of the stem. The user can define a maximum percentage of opening and closing as well as define an increase in speed and decrease in speed

If the component is in forced mode, the output position is the value FoV defined by the user; if not, the output is the result value of the sequential block defined in the abstract component Base_ANA.
