Safety & Pressure Reducing Valves for Hydrogen Applications
Hydrogen – The energy source for the future.
Electrolysis
The electricity generation industry is facing difficulties in finding sustainable and eco-friendly resources and methods to produce electricity, as are the engineers and companies working on sustainable and green mobility concepts. While the production of hydrogen is currently feasible through the use of fossil fuels, newer and more innovative processes like electrolysis have been gaining popularity. In this process, water is split into hydrogen and oxygen.
Green Energy
If the electricity needed for producing hydrogen comes from renewable sources, then that hydrogen is considered green. This method of acquiring an energy source and a possible way to store electricity (since the process can be reversed) is innovative and has great potential for future mobility. It’s evident that green energy is going to be crucial in the future.
Safety
Goetze safety valves ensure safe handling of hydrogen at every stage, from retrieval to application in electric processes or fuel cell vehicles at hydrogen filling stations. Goetze valves provide protection during high-pressure filling processes or storage of liquid hydrogen in tanks. This ensures safer handling of hydrogen and makes it a more appealing option for both human use and environmental impact.

Hydrogen Pressure Reducing Valves
420 Series – Goetze Safety Relief Valve for Hydrogen Applications
To support hydrogen production, e.g. in the electrolysis process, safety valves are required that reliably protect the systems even at low pressures and low volumes. Thanks to TÜV and European component approval, the miniature safety valves in the 420 series enable the use of tested and approved quality, even in these applications, with neutral and non-neutral gaseous and liquid media.
2400 Series – Goetze Safety Relief Valve for Hydrogen Applications
The safety valves in the 2400 series are fully approved for vapours and gases as well as liquids. All valve components are specially cleaned during the manufacturing process and are therefore generally oil- and grease-free in accordance with DIN EN 12300. The use of high-alloy stainless steels 1.4404 and 1.4408 makes the safety valves extremely resistant in extremely cold temperature ranges. An FDA-compliant sealing material is used for use with gases that come into contact with foodstuffs.
492 Series – Goetze Safety Relief Valve for Hydrogen Applications – Rotatable Outlet
Thanks to its special technical design and construction, the 492 series covers an unrivalled pressure range of up to 1500 bar. The valve is particularly suitable for hydrogen, whereby the high-performance materials used, such as PAI or PEEK, enable a very high level of tightness. This high level of tightness is maintained even after the valve has responded several times.
451 Series – Goetze Safety Relief Valve for Hydrogen Applications
These safety valves are particularly suitable for applications involving hydrogen. Thanks to the versatility of the 451 valve with optionally available back pressure compensating stainless steel bellows or lifting, this safety valve is in demand throughout the entire hydrogen value chain.
461 Series – Goetze Safety Relief Valve for Hydrogen Applications
The consistent expansion of this series with smaller nominal diameters now also enables the safety valve to be optimised and thus economically sized for smaller blow-off quantities. The proven range of variants allows the valve to be used for different media in different aggregation states. This series is well-suited and frequently used in measurement and control technology systems and gas mixing stations, for example.
455 Series – Goetze Safety Relief Valve for Hydrogen Applications
Our flange series 455 is used in applications where large volume flows need to be protected. In this area of system protection, flange connections are often installed in existing pipework systems. The use of high-quality materials with excellent media resistance and the option of achieving the highest level of tightness to the atmosphere by employing a back-pressure compensating bellows, this safety valve is suitable for almost any application.
451FL Series – Goetze Safety Relief Valve for Hydrogen Applications
These flanged safety valves are particularly suitable for applications involving hydrogen thanks to the versatility of the 451FL valve with optionally available back pressure compensating stainless steel bellows or lifting, this safety valve is in demand throughout the entire hydrogen value chain.
484 Series – Goetze Pressure Reducing Valve for Hydrogen Applications
This diaphragm or piston pressure reducing valve made of stainless steel, with sleeve connections for hydrogen applications, is characterised above all by its particularly high flow rates and its low pressure loss, even with high power requirements. The pressure is set without tools using the ergonomically shaped handwheel. The extremely small pressure drop in the control operating range makes this high-performance pressure regulator unrivalled.
