(1) : Kvs Flow coefficient: Flow in m³/h with valve open and pressure drop of 100 kPa. - 100 kPa = 10 mCA = 1 bar
(2) : bar Maximum pressure differential (∆p max) permitted by actuator.
(3) : s Time (seconds) necessary for actuator to make the complete valve run.
(4) : actuator with emergency closure.
