A valve arrangement, an actuator arrangement and related methods, in which a first cleaning position is detected by mechanically transfer at least a portion of a movement of, or provided to, a first valve stem into a first movement of a second valve stem, such that a second valve member is moved towards a first conduit while the second valve member still sealingly engages a second valve seat, whereby a movement of a first valve member is detectable by a control unit by detection of the first movement of the second valve stem in a direction which extends towards the control unit.
