CO₂ valves: The green future in refrigeration and air conditioning technology at
High pressure
In a world where efficiency, climate protection and legal requirements are becoming
increasingly important, CO₂ valves are at the forefront of technical
innovation. They are an important component of modern systems that rely on
sustainability and precision. Especially since the tightening of the F-gas
regulation, which drastically restricts the use of environmentally harmful refrigerants,
CO₂ has become indispensable as a natural substitute. But with the opportunities also
come challenges: CO₂ applications work with high pressures, require high precision,
absolute reliability and a long
service life – requirements that only state-of-the-art valve technology can meet.
Our CO₂ valves are characterized by high efficiency in the smallest of spaces.
They therefore not only meet the technical requirements but also enable companies to
reduce costs at the same time.
High-performance sealing materials and stainless-steel body material as well as our
modular system offers you the greatest possible flexibility to find the right valve for
your application. Our CO₂ valves have been tested and further developed together with
our customers. At RSG you get valves with a long service life, high reliability and great
energy efficiency.
CO₂ valves are more than just a technical product – they are a key component in the
industrial development of refrigeration systems and heat pumps for a sustainable and
legally compliant future.
Why are CO₂ valves so important for industry and technology?
CO₂ valves are indispensable components of modern industrial systems and guarantee
safe operation even under extreme conditions. Thanks to their ability to handle high
pressures and temperatures, they are the ideal choice for applications in refrigeration
and air conditioning, as well as in medical technology, the aviation industry and plant
engineering.
Our valves have been specially designed and developed for CO₂ applications and are
therefore the optimal solution when using this natural, high-performance refrigerant.
The use of these valves is to make processes more efficient, reduce operating costs and
at the same time while ensuring the highest safety standards.

CO₂ valves: technology and production
How are CO₂ valves manufactured?
The production of our CO₂ valves involves a precise and optimized process that extends
from material procurement to delivery. Each phase is designed to ensure the highest
quality and safety.
The development process: from concept to production
Our development process begins with a precise analysis of the customer requirements.
Engineers work with CAD software to design valves that are both functional and
efficient. Simulations and calculations help to predict the behaviour under real
operating conditions.
After validation, the designs move on to the prototype phase into the pre-series phase.
Once the field tests have been completed, the products are transferred to series
production.
Prototyping and simulation: precision right from the start
Before a valve goes into production, we create prototypes that are tested in-house in
simulated
environments and on site at the customer’s premises in their systems.
These tests ensure that the valves meet the pressure, temperature and chemical
resistance requirements,
Using the latest software solutions, we minimize errors and optimize designs at an
early stage.
Material selection: Why stainless steel and optimized sealing materials?
For our CO₂ valves, we only use the following for wetted components stainless steel and
high-performance sealing materials that are optimized for use with CO₂ and are
extremely wear-resistant. This enables us to guarantee a long service life and minimize
maintenance costs.
Assembly and test procedures: Quality steps in detail
During production, our valves undergo strict testing procedures. These include:
- Leak tests to rule out leaks
- Load tests to ensure pressure resistance
- Functional tests to guarantee reliability in real applications
Technical properties of CO₂ valves
How do CO₂ valves work in high-pressure systems?
In high-pressure systems, our CO₂ valves precisely regulate the flow and pressure of the
medium.
Thanks to their robust design, they can withstand pressures of up to130 bar. Their
reliable function ensures that systems work safely and efficiently, even under extreme
conditions.
With our CO₂ valves, we offer solutions that are both technically and economically
convincing. Whether for standard applications or highly specialized requirements – we
are your partner for reliable and innovative valve technology.
Areas of application for CO₂ valves
For which industries are CO₂ valves indispensable?
CO₂ valves are essential in numerous industries as they ensure efficiency, safety and
precision.
The most important industries include:
Refrigeration technology:
Due to the F-Gas Regulation, CO₂ valves are an
indispensable component in cooling / freezing systems, and air conditioning
units especially in environmental simulation and medical technology, as CO₂ is
an extremely environmentally friendly alternative to conventional refrigerants.
- Energy: In heat pumps and climate-friendly heating systems, they regulate the
CO₂ cycle efficiently. - Chemicals: They control highly complex processes that take place under high
pressures and temperatures. - Oil and gas industry: CO₂ is pumped into oil fields, where it mixes with the crude
oil and reduces its viscosity so that the oil flows better to the production wells. - Concrete and construction industry: CO₂ is used to harden concrete (carbon
curing) - Food and pharmaceutical industry: CO₂ valves are used here where strict
hygiene regulations and process reliability are required. CO₂ is used to carbonate
beverages such as beer, lemonade and mineral water. CO₂ atmosphere in
packaging extends the shelf life of food.
These valves are ideal for applications that require both high performance and
precision, even under extreme conditions.
How do CO₂ valves optimize refrigeration systems and heat pumps?
Our CO₂ valves play a key role in the efficiency and performance of modern
refrigeration systems and heat pumps, as they are:
- Compact
- Reliable
- Durable
- Energy efficient
- Service-friendly
These properties result in an optimum price-performance ratio for this and increase the
competitiveness of our customers.
Quality and safety
Which test procedures guarantee the performance of our CO₂ valves?
To ensure the quality and reliability of our CO₂ valves we subject them to a large
number of stringent tests:
- Leak tests: Ensure that no CO₂ escapes and that the valves remain tight even
under extreme pressures - Stress tests: Simulation of real operating conditions, including high pressures
and temperatures - Long-term tests: Evaluation of performance after millions of switching cycles, to
guarantee longevity
These tests are carried out in our own laboratory and also in cooperation with our
customers, who carry out tests under real conditions in their devices.
This close cooperation ensures consistently high quality.
How do we ensure that CO₂ valves can withstand the highest pressures?
Our CO₂ valves are specially developed for high-pressure applications. For this we rely
on:
- High-strength materials: Stainless steel and high-performance sealing materials
ensures maximum pressure and corrosion resistance - Precise manufacturing: State-of-the-art CNC technologies and automated
processes minimize manufacturing tolerances - Certified test methods: Each valve is individually tested to ensure that it can
withstand pressures of up to 130 bar without any problems
Thanks to these measures, our valves can be used reliably even in the most demanding
applications.
Frequently asked questions about CO₂ valves
How long is the service life of a CO₂ valve?
The service life depends on the operating conditions. As a rule, our valves exceed
millions of switching cycles and can therefore work reliably for many years especially
with regular maintenance.
Which materials are best suited for CO₂ valves?
For CO₂ valves, we recommend stainless steel for housings and high strength sealing
materials. These materials offer high resistance to pressure and corrosion resistance,
which leads to an extended service life.
How are CO₂ valves adapted to specific requirements?
Our modular system makes it possible to configure valves individually. Depending on
requirements, seals and connection options can be adapted to meet specific operating
requirements.
