Elaflex ZVF 50, Automatic, Overwing, Aviation Fuel Nozzle, ATEX Approved

ZVF 50 is a high-flow aviation nozzle for overwing and helicopter refuelling. It has replaced the well- known ZVF 40.

The nozzle impresses by its good handling:

  • Light lever action; the built-in LeverAssist® further reduces the required hold-open force by 75 %
  • Low weight
  • Easy rotating swivel
  • Ergonomic construction

The 2" flow ensures a low pressure-drop and high flowrate. Also, the design efficiently minimises pressure shocks. A sensitive flow control allows easy top up.

ZVF 50 is in alignment with the requirements of the JIG guidelines (Joint Inspection Group) and features a number of safety enhancements:

  • The Colour Coding avoids misfuelling between JET (black), AVGAS (red) and UL (green).
  • The use of non-ferrous metals protects against fuel contamination and makes the nozzle suitable for biofuels of today and the future.
  • Integrated bumpers prevent the aircraft surface from damages.
  • Improved spout change system with threaded or Push-Twist-Lock connection. Common to both solutions: spouts can be changed without tools and rotated in any position – this is important for JET-A1 spouts. Simplified inspection and cleaning of the strainer, safe prevention of unintended release. If spout types are regularly changed, we suggest the timesaving Push-Twist-Lock option.
  • The corresponding nozzle boot NB-ZVF 50 (see picture right hand side ) serves for the safe installa- tion on board of airfield refuellers. It is available for all ZVF 50 configurations. For further details, please see Elaflex Information 10.15.

An automatic shut-off nozzle can only be used on pumped dispensing systems, they will not work on gravity-fed dispensing systems.
