Advantages of GEFA valves in biogas plants
Biogas plants are a great way to generate renewable energy from organic materials through the microbial decomposition process. However, due to the nature of the biogas and other water polluting substances and residues, biogas plants can also be a source of odors, pollutants and noise. By installing GEFA valves in your biogas plant, you can ensure quality, reliability and safety.
With our powerful product range we offer you the possibility to get suitable knife gate valves and butterfly valves for your biogas application. Our offer ranges from nominal size DN50 up to DN1800!
DOMINO knife gate valve for high operational reliability
The high operational reliability of our gate valves is ensured above all by their tight shut-off in both pressure flow directions and their insensitivity to pressure surges. In addition, the knife gate valves still function smoothly even after long downtimes typical of the industry.

Butterfly valves with high life expectancy
Our centrally mounted butterfly valves are ideally suited for the biogas industry due to their rational and safe use. The one-piece housing is completely elastomer lined with the seat ring as a multifunctional sealing element. The edge-free transition to the dovetail guide guarantees secure locking with high tear resistance. High flow velocities, crust formation and abrasive media are optimally controlled.
