Hydraulic Components - Controllers


Within flow systems, it is often desired to control flow or pressure at a given location. To achieve this goal some type of control device is needed. The curve data (Cv vs. %open or Kv vs. %open) from the control valve manufacturer can be defined in the database to incorporate into the system design. Users have the option to automatically size the control valve to determine the flow coefficient (Cv) for the defined operating conditions, i.e., control valve set point.

The table below shows the application of different controller elements available in the FluidFlow database:

The table below shows the required data input and the output for the controller components. Note that the results table varies depending upon the fluid phase state and the visible properties selected by the user.
