Hydrogen Explosion Relief Valve: Enhanced Safety for Hydrogen Systems

As the world moves away from fossil fuels, it is crucial to continuously innovate and develop new technologies that can harness the power of sustainable energy sources. Hydrogen, with its potential as a CO2-free fuel and its ability to be stored, plays a vital role in this energy transition.

The Sigma Valve for Hydrogen delivers exceptional performance. It is specifically tested for use in hydrogen applications, including but not limited to reciprocating compressors and combustion engines.

Our explosion pressure relief valve goes beyond expectations by resealing itself after an explosion, thanks to a spring-loaded mechanism. The mechanism blocks oxygen from re-entering after an explosion, providing an additional layer of safety, helping to mitigate the risks of re-ignition, and further damage.

Key Fuel Facts

  • Hydrogen's Potential in Maritime Decarbonization: Hydrogen internal combustion engines hold great promise in reducing the carbon footprint of the maritime shipping industry. Studies project that hydrogen could reduce emissions in this sector by up to 80% by 2050. The Sigma Valve's patented technology is engineered to meet the unique safety demands of hydrogen service.
  • Flame Arresting Challenges: Hydrogen flames can propagate through smaller gaps compared to methane, highlighting the need for specialized flame-arresting solutions.
  • Hydrogen's High Explosion Potential: Hydrogen has a wide flammable range (4%-75% concentration in air), underscoring the importance of robust explosion prevention measures.
  • Safety Standards: The Sigma Valve is designed to exceed relevant industry safety standards, providing peace of mind in demanding hydrogen applications.
  • Diverse Applications: Beyond its potential as a clean fuel, hydrogen is widely used in industries like petroleum refining, ammonia production, methanol production, and steel production.
