Valve specialist Gemü has successfully had several butterfly valves certified in accordance with DIN EN 13774 and DVGW-CERT ZP4110. The test, conducted by the German Technical and Scientific Association for Gas and Water (DVGW), confirms that the valves are fully suitable for use with hydrogen in gaseous form.
The butterfly valves Gemü R480, R481, R487, R488 Victoria, as well as Gemü R470, R471, R477 and R478 Tugela, are suitable for operation with hydrogen. The certification applies to all body configurations and pressure ratings.
This makes Gemü butterfly valves suitable for a multitude of industrial applications in the hydrogen sector. They are used in electrolysis, PPE and fuel cell plants, as well as in distribution networks for isolating and controlling gas and liquid flows. They are also used in auxiliary processes such as treatment systems for cooling water, gas and water.
In power-to-liquid plants, they enable precise control of hydrogen, CO2 and synthesis gas flows in reactor and supply circuits.
The certified series comply with all technical requirements for hydrogen applications, including a compact design, short switching times and suitability for a wide range of media.
With certification complete, Gemü butterfly valves are now available for all applications in which hydrogen is used in a gaseous state. Gemü says this means that customers can benefit from proven solutions for safely, reliably and efficiently operating hydrogen-based systems.
