Hollow stream nozzles with shut-off for the delivery of firefighting water in the form of full jet and selectable spray jet.
HS nozzles can be conveniently and continuously adjusted from completely closed via full jet to spray jet between 0 - 120° by twisting the rubber coated head.
Switching sequence: Closed – full jet – spray jet.
The spray teeth have flat deflection surfaces on the inside and produce a spray the centre of which is directed forwards. This results in a large spray jet throw distance. Large drops for reach, small drops for cooling. As a result, universal and effective use of the HS nozzles is possible.
Absolute corrosion resistance to seawater
The simple design means the nozzle is not prone to repair
Low operating forces
Structure of HS nozzles
All bills of material have an identical structure. The only difference between types HS10, 12, 16, 20 is that they have different valve plates at the front. These are marked at the front as “D10”, “D12”, “D16” and “D20”.
