  • the medium controlled by the valve can no longer get between the needle and the seal.
  • the seal can no longer by solid particles, for example of effect paints od.
  • the valve may become inoperable by sticking the needle in the seal. Since the media side of the seal and the pressure-free area located on its other side are always hermetically separated, the valve function can no longer be affected by pressure leakage.

  • valves with diaphragms permanently connected to the valve needle are already known per se.
  • the valve arrangement according to the invention has various advantages, in particular various advantages, particularly in paint shops, such as the possibility that the valve can be reliably actuated with relatively low air pressure, inter alia because the membrane is affected by the present invention.
