The new ZVF 50 is a high-flow aviation nozzle for overwing and helicopter refuelling. The nozzle impresses by its improved handling, resulting from light lever action, easy rotation swivel and lowweight ergonomic construction. A full 2-inch flow ensures a low pressure-drop and high flow rate. Also, the design efficiently minimizes pressure shocks. A sensitive flow control allows easy top up. Color coding avoids mix-ups between JET and AVGAS fuels.
