The HFH7 is a top-of-the-line solution for hydrogen fueling applications up to CL4000. Its special floating ball valve design guarantees safety, low emissions and internal tightness. The innovative double insulation layer sealing system, made of polymeric materials and expanded graphite, provides a fire-safe design and prevents contamination. Additionally, the packing system is equipped with an RGD o’ring to prevent failures and hydrogen contamination. The HFH Series is available with welding or threaded connections and is the ultimate choice for high-pressure fueling systems.
