For vehicle safety during an accident or while refuelling, regulations require an approved check valve to be installed in the filling system of natural gas vehicles.
Stainless steel models from Stäubli are available in 6 mm and 9 mm nominal bores, suitable even for the highest flow rates. Naturally certified according to ECE, TÜV or AGA standards. These valves also feature an ultra-quiet internal design, ensuring silent operation during refuelling.
