Roll-over valve Ventilation of the fuel tank in the operating condition. In addition, a rollover protection function is integrated for preventing fuel leakage in the event of an accident.
Venting and exhausting valves Venting of the tank when filling until the maximum fuel level is reached. Shutdown of the filling process when refueling via a floater. In addition, a rollover protection function is integrated for preventing fuel leakage in the event of an accident.
Combo valves Combination of various customer-specific functionalities which unite the advantages of individual valves in a "combo valve", e.g. liquid trap with integrated ROV and FLVV
Pressure control valves/pressure relief valves Control of the specified re-fuelling intervals (trickle-fill)
Active suction jet pump Use and integration of the venturi effect for the reinforcement of currents or active extraction LCO (liquid-carry-over) from tank ventilating systems.
Check valve Prevention of fuel back splash in the filler tube during and after refuelling, as well as prevention of fuel leakage from the tank into the environment with damaged filler tube, e.g. from an accident.

Fuel management

Based on our core competence in valve technology, we offer a wide service spectrum in the area of fuel management - from the design of tank ventilation and filling functions to the closed-coupled fuel regulation. Due to our modular systems, we implement customized adaptations at attractive investment costs. In doing so, future requirements for the next generation from global regulatory emission requirements are already covered.
