  • (1) : Kvs Flow coefficient: Flow in m3/h with valve open and pressure drop of 100 kPa. - 100 kPa = 10 mWG = 1 bar

  • (2) : bar Maximum pressure differential (∆p max) permitted by actuator.e.

  • (3) : Type of rotor;

    • For 3-port valves:

      • slipper = left or right lateral port always open.

      • butterfly = central port always open.

  • (4) : Length flange to flange.

  • (5) : Coupling possible only with AVF 171 linkage.
