.IDEAS.Fluid.Actuators.Valves.TwoWayButterfly

Information

Two way valve with the flow characteristic of a typical butterfly valve as listed below.

Implementation

The model assigns a Kv based on the table at mydatabook.org. The Kv values listed in the parameter Kvs are reasonable assumptions, but the actual value can depend much on the design of the specific valve. Moreover, the Kv values for DN value smaller than DN 150 are a quadratic extrapolation from the value at DN 150.

Revisions

• June 10, 2021, by Michael Wetter:
  Changed implementation of the filter and changed the parameter order to a constant as most users need not change this value.
  This is for #1498.
• December 22, 2020 by Michael Wetter:
  Add parameter Kvs.
• December 20, 2020 by Filip Jorissen:
  Revised implementation with default Kv computation.
• July 8, 2018 by Filip Jorissen:
  First implementation.
