Hydrogen compliant Instrumentation Valves and DBB Piping Ball Valves
For more than 20 years, we have been supporting hydrogen as a medium with our valves. All valves and manifolds as well as our Double Block & Bleed Piping Ball Valves are suitable for up to 100% hydrogen use.
In other words, our instrumentation valves and process valves can also be used safely in natural gas applications with, for example, a 20% hydrogen blending. This feature is of particular interest to natural gas plant operators and gas network operators who want to convert their natural gas pipelines for hydrogen.
Hydrogen compliant Instrumentation Valves
All our Instrumentation Valves are suitable for up to 100% hydrogen use:
E Series Manifolds, Gauge Valves and Pressure Gauge Accessories, Soft Seated Valves and Manifolds, Schneider DirectMount Systems, Mini Valves and Rupture Disc Holders, Modular Mounting Systems, Monoflanges & VariAS-Blocks, Needle Type Globe Valves, Ball Valves, F Series Manifolds & Multi-Way Cocks, Air Headers and Flange Adapters.
Hydrogen compliant Double Block & Bleed Piping Ball Valves
The 2 Piece Design and 3 Piece Design, Flanged Style of our Double Block & Bleed Piping Ball Valves (Taurus Series) is suitable for up to 100% hydrogen service.
Other materials are also suitable for hydrogen use. In such a case, we recommend to consult our hydrogen experts personally in order to be able to select the best possible material for your specific requirements.
You should also ensure that non-metallic valve materials such as seals and lubricants are compatible with the hydrogen medium. A list of recommendations can be found in the designated standards and norms (Sandia, ISO / TR, SAE). See also the section on sealing materials below.
Suitable Metallic Materials
| Material | Operating Limits | Recommendation |
| 1.4401 / 1.4404 | -40°C / +538°C |
For hydrogen applications, our experts recommend |
| 316 / 316L | -40°C / +538°C | |
| 1.4571 | -40°C / +538°C | |
Open Hydrogen Environment (Option W1)
In the case the valve is mounted in an open, ventilated hydrogen application - for example in a forced-ventilated room, or even outdoors, there is no danger of an explosive atmosphere, and the escaping hydrogen is harmless to the environment. For such an application, you can use our standard valve head units.Our Recommendation:
| Valve Head Unit | Sealing System |
| Our Standard Valve Head Unit | PTFE |
Closed Hydrogen Environment (Option W2)
Our Recommendation:
| Valve Head Unit | Sealing System |
| Special Valve Head Unit - Depending on the field of application |
Valve Head Unit tested acc. to ISO 15848-1 (TA-Luft Valve Head Unit) or Bellows Sealed Head Unit |

- Leak Test with Helium using the Sniffing Method acc. to ISO 15848-2
( 1 ) Test Scope: 10%
( 2 ) Test Pressure: 6 bar
( 3 ) Leak Tightness Class B
