Pressure-controlled valve for large electrolysers
Precise gas flow control on the H₂ and O₂ sides
Our pressure-controlled valve from the 2/977 series was specially developed for use in large-scale water electrolysers.
It reliably controls the gas flow and pressure on the hydrogen and oxygen sides and is designed for use in PEM and alkaline electrolysers.
The available flange connection design makes the valve particularly suitable for large nominal diameters and high volume flows in industrial electrolysis plants.
Typical applications in the electrolyser
- Pressure and flow control on the H₂ side (product gas)
- Pressure and flow control on the O₂ side
- Use in header and collector pipes
- Control valve in distribution lines and bypass lines
- Integration into modular skids and container electrolyzers
