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 focus 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 opportunities come challenges: CO₂ applications operate at 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 housing materials, as well as our modular system, offer you the greatest possible flexibility in finding the right valve for your application. Our CO₂ valves have been tested and further developed in collaboration with our customers. We provide you with valves that offer 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.

CO₂ valves: Technology and manufacturing
How are CO₂ valves manufactured?
The manufacture 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 detailed analysis of customer requirements. Engineers use CAD software to design valves that are both functional and efficient. Simulations and calculations help predict behavior under real operating conditions. After validation, the designs move from the prototype phase to the pre-production phase. Once field trials have been successfully 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 facilities. These tests ensure that the valves meet the requirements for pressure, temperature, and chemical resistance. Using state-of-the-art software solutions, we minimize errors and optimize designs at an early stage.The manufacture of our CO₂ valves involves a precise and optimized designs at an early stage.
Material selection: Why stainless steel and optimized sealing materials?
For our CO₂ valves, we use only stainless steel and high-performance sealing materials for components that come into contact with media. These materials are optimally suited for use with CO₂ and are extremely wear-resistant. This ensures a long service life and minimizes maintenance requirements. Assembly and testing procedures: Quality steps in detail.
During production, our valves undergo rigorous testing procedures. These include:
- Leak tests to rule out leaks.
- Stress tests to ensure pressure resistance.
- Functional tests to guarantee reliability in real-world applications.
Technical characteristics 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 to 130 bar. Their reliable function ensures that systems operate safely and efficiently, even under extreme conditions. With our CO₂ valves, we offer solutions that are both technically and economically impressive. Whether for standard applications or highly specialized requirements, we are your partner for reliable and innovative valve technology.
Areas of application for CO₂ valves In 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 have become an indispensable component in refrigeration/freezing systems and air conditioning units, particularly 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 efficiently regulate the CO₂ cycle.
- Chemistry: You 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, allowing the oil to flow more easily to the production wells.
- Concrete and construction industry: CO₂ is used to cure 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. A 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
- Compact
- Reliable
- Durable
- Energy efficient
- Are service-friendly.
These characteristics result in an optimal price-performance ratio for this valve and increase our customers' competitiveness.
How do we ensure that CO₂ valves can withstand the highest pressures?
To ensure the quality and reliability of our CO₂ valves, we subject them to a variety of rigorous 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 testing: Performance evaluation 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 conduct tests under real conditions in their own equipment. This close cooperation ensures consistently high quality.
How do we ensure that CO₂ valves can withstand the highest pressures?
Our CO₂ valves are specially designed for high-pressure applications. To achieve this, we rely on:
- High-strength materials: Stainless steel and high-performance sealing materials ensure maximum pressure and corrosion resistance.
- Precise manufacturing: State-of-the-art CNC technologies and automated processes minimize manufacturing tolerances.
- Certified testing 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.
