Biogas & Anaerobic Digestion Solenoid Valves
Our range of biogas solenoid valves is designed for safe and reliable control of gas flow in anaerobic digestion and renewable energy systems. These valves are suitable for methane-rich biogas environments, offering durable construction and ATEX-certified options for hazardous areas.
What Is Biogas & Anaerobic Digestion?
Biogas is produced through the anaerobic digestion of organic materials such as agricultural waste, food waste, and sewage sludge. This process generates a mixture of gases, primarily methane and carbon dioxide, which can be used as a renewable energy source.
Due to the presence of flammable gases, safe and certified flow control is essential.
Why Use Solenoid Valves in Biogas Systems?
Solenoid valves play a key role in:
→ Controlling gas flow safely and automatically
→ Isolating sections of pipework
→ Managing pressure and distribution
→ Supporting system safety and shutdown processes

Transforming Organic Waste into Renewable Energy
The United Kingdom generates over 16 million tonnes of food waste annually, equating to approximately 251 kg per person each year. This significant volume of organic waste presents an opportunity for sustainable energy production through anaerobic digestion (AD). By processing food waste, agricultural manure, and organic materials in AD plants, biogas—a renewable energy source primarily composed of methane—is produced, reducing reliance on fossil fuels and lowering carbon emissions.
The Anaerobic Digestion Process
Anaerobic digestion involves a series of biological processes where microorganisms break down biodegradable material in the absence of oxygen. This process yields biogas, consisting mainly of methane (CH₄) and carbon dioxide (CO₂), along with trace amounts of hydrogen sulphide (H₂S). Post-digestion, the residual material, known as digestate, can be utilised as a nutrient-rich fertilizer, while the biogas is harnessed for energy applications.
Importance of Specialised Solenoid Valves in Biogas Systems
Handling biogas requires components that can withstand its corrosive and potentially hazardous nature. Solenoid valves play a crucial role in controlling the flow of biogas within AD systems. Key considerations for these valves include:
Material Compatibility: Due to the presence of H₂S, valve components should be made from stainless steel or other corrosion-resistant materials.
Seal Integrity: Seals made from Viton (FKM) are recommended over nitrile for higher H₂S concentrations, ensuring long-term durability.
Pressure Handling: Valves must accommodate varying pressure levels, especially in systems where biogas is compressed for storage or transportation.
Safety Certifications: Compliance with ATEX and EN161 standards is essential for safe operation in potentially explosive environments.
