Butterfly Valve Series GEMÜ 490 Edessa
- Manual, pneumatic and motorized butterfly valves for applications across the hydrogen value chain
- Universally compatible due to a avariety of available materials
- Operating pressure: up to 10 bar
- Media temperature: up to 200 °C
- Nominal sizes: DN 25 – 1200
- Customized accessories for automation and process optimization available
Butterfly valves for Hydrogen applications
- Due to a variety of materials, the GEMÜ butterfly valves are universally compatible.
- The construction enables many possible combinations of disc, liner and body.
- For all nominal sizes, butterfly valves are effective as short shut-off valves with high flow rates.
- Various manual, pneumatic and motorized actuators are available for all GEMÜ butterfly valves
Key features of PTFE-seated butterfly valves
- Liner and disc materials can be flexibly combined
- Disc and shaft from a single casting with spring loaded seal system
- Standardized top flange acc. to ISO 5211 for various actuators
- Low torque due to special liner geometry
Advantages
- Butterfly valves are effective as compact shut-off valves with high flow rates and universally compatible due to a variety of available materials. The PTFE liner with PFA-coated disc offers highest purity for ultrapure water applications like PEM electrolysers.
Application areas
- Water treatment
- DI-Water treatment
- Ultrapure water supply
- Electrolyzer water supply (PEM)
- E-fuel production and storage
Contact us
- Hydrogen as a medium places stringent requirements on valves. Above all, the small molecular size of the volatile gas quickly becomes a challenge when selecting materials. No matter whether it's about the right material or the corresponding approval, we are by your side in the selection of the right valve. Interested?
