WEH® Defueling Nozzle TK6 H₂
Cars running on hydrogen have to be serviced and checked regularly, a process involving the discharge of their pressurized fuel tanks. The WEH® TK6 H₂ defuelling nozzle with venting valve has been designed for this specific purpose.
The defuelling nozzle is simply engaged onto the receptacle of the cars and the knurled spindle fully turned until the receptacle is fully open. Discharge can now take place through the lateral media discharge vent.
