The invention comprises a needle valve-related arrangement (1) with a rotating spindle (11) in an enclosure, whereby a rotary movement of the spindle in one direction induces movement in a firs valve part (12) on the spindle in a first direction towards a second valve part (13) and vice-versa. Pressure to create sealing interaction of the valve parts (12, 13) is achieved with the aid of a spring arrangement (35). |
