Valve technology for hydrogen, heat pumps, CO₂ cooling, and more—as flexible as your application.
Valves for renewable energies – For systems that make energy clean
Challenges in valve technology for renewable energies
Anyone working in the renewable energy sector knows that there is hardly any other field in which technical requirements are developing so dynamically. From heat pump systems and hydrogen technology to CO₂ cooling in PV systems—the range of media, temperatures, pressures, and interfaces is enormous.
And that is precisely where the challenge lies. Standard solutions often fall short. What works today may be inadequate tomorrow—whether in terms of media resistance, energy efficiency, or documentation requirements.
Many interested parties ask us:
- How do my systems remain flexible when media or print areas change?
- Which valves are suitable for CO₂, hydrogen, or heat transfer fluids?
- Are there solutions that are both durable and economical?
We know these questions—and we have concrete answers.
Valves for renewable energies with a system
We develop valve solutions that grow with your technology. Whether solar thermal, wind power, hydrogen, or heat pumps: our control valves, coaxial valves, plastic valves, and metal valves for renewable energies can be tailored to individual processes—without compromising on time, budget, or safety.
You receive valves that can be configured in a modular fashion—whether for bio-based media, CO₂ refrigeration circuits, gaseous hydrogen, or energy conversion systems. With designs that are just as impressive in confined spaces as they are in high-pressure systems.
Advantages of our valves for renewable energies
- Media compatible: Resistant to CO₂, glycols, hydrogen, ammonia, and many more
- Pressure-resistant and safe: Designed for applications up to 130 bar or more
- Economical to operate: low maintenance, durable, and adaptable
- Quickly available: Thanks to modular technology and our own warehouse
- Scalable: Suitable for prototypes, small series, and series projects
- Ready for the future: Also for new media such as synthetic fuels
Examples of applications in the field of renewable energies
- Hydrogen in building services engineering: PVDF plastic valves with separating membranes in hydrogen storage systems for small buildings.
- CO₂ cooling for heat pumps: Servo-controlled coaxial valves regulate CO₂ refrigerant in transcritical heat pump circuits – up to 130 bar.
- Solar thermal valves for large-scale systems: Stainless steel valves with PTFE seals in systems for feeding heating energy from solar collectors into the grid.
- Gas circuits in wind power stations: Control valves with high repeatability for controlling rotor blade heating systems.
- Biomass condensation circuit: Combination of metal valves and high-performance ball valves for controlling exhaust gas heat exchangers.
Why our valve solutions work for renewable energies
Renewable energies are not a topic for the future—they are the present. Our valves are not created in a vacuum, but in collaboration with companies that need solutions today that will still work tomorrow.
We combine many years of experience with a modular system that offers more than just standard solutions. Whether you are changing a single connection or rethinking an entire plant layout, we supply valves that can be adapted. Fast, well thought-out, compatible. Because a good solution has to work not only on paper, but also in real-life processes.
RSG: Valves for progress
We have been developing valves for industry for more than 30 years. Today, applications in the field of renewable energies are among the most important areas of our work. Our customers appreciate not only the technology, but also everything that goes with it:
- Development, manufacturing, and logistics in one location
- ISO-certified processes and traceable quality
- Dedicated contacts who also think technically
- High material availability thanks to our own warehouse
- Valves "Made in Germany" – not just on the label
Our valve technology works just as well in offshore wind farms as it does in CO₂ cooling systems or solar thermal power plants. Because we listen, think ahead—and deliver.
