GAS VALVES AND EQUIPMENT FOR INDUSTRIAL GAS APPLICATIONS

A comprehensive range of high-performance cylinder valves is designed to meet the diverse requirements of industrial gas supply systems. With multiple inlet and outlet configurations, these valves ensure full compatibility with a wide variety of industrial gas cylinders and distribution setups. The range is also compatible with medical gases such as nitrous oxide and medical air, supporting applications where cleanliness, reliability and safety are critical.

Designed for durability and long-term performance, Rotarex cylinder valves are qualified for up to 2,000 operating cycles in accordance with ISO 10297, ensuring extended service life and reduced maintenance in demanding industrial environments.

Rotarex offers a wide range of valves featuring multiple technologies, including standard cylinder valves, innovative residual pressure valves (RPVs) and integrated valve and pressure regulator solutions (VIPRs).

• Standard cylinder valves are designed with proven O-ring sealing technology to ensure reliable gas tightness and safe operation.
• Residual Pressure Valve technology helps to enhance gas safety by preventing contamination and maintaining positive pressure inside the cylinder, even when it is empty.
• VIPR solutions build on this safety foundation by combining multiple functions in a compact design that simplifies installation, improves protection and optimises gas control.
• Refrigerant valves for specific gas applications complete the range, enabling safe, reliable and continuous industrial gas supply across a wide range of applications.

Industrial gases are used across a wide range of industrial environments where precise control, safe operation and reliable performance are essential. To meet these requirements, application-specific industrial gas systems provide the right combination of equipment, system design and expertise.

• Metallurgy: Industrial gases are widely used in metal and metallurgy applications, including MIG and TIG welding and cutting operations, as well as for heat treatment processes requiring controlled or protective atmospheres. Dedicated gas solutions help provide stable process conditions, ensure material integrity and achieve consistent metallurgical properties.
• Food processing: In the food and beverage industry, gases support beverage carbonation, freezing and cooling processes, modified atmosphere packaging (MAP), and inerting of tanks and production lines, helping preserve product quality, extend shelf life, and maintain food safety.
• Chemical & pharmaceutical processing: Industrial gases play a key role in process atmosphere control, chemical reactions and synthesis. Reliable gas solutions provide stable gas supply and material compatibility, ensuring safe, repeatable and compliant production processes.

In all these applications, industrial gases enable and control industrial processes, protect materials and equipment from contamination or degradation, and improve operational safety and efficiency. Reliable gas equipment, such as cylinder valves, pressure regulators and gas supply systems, is therefore a critical solution to meet the specific requirements of each application.

Welding gases are selected based on the welding process, the materials to be joined and the required weld quality. Precise control of gas pressure and flow rate is essential to ensure flame stability, weld quality and operator safety.

In addition to shielding gases such as argon, carbon dioxide and gas mixtures used in arc welding processes, oxyacetylene welding relies on a combination of oxygen and acetylene to generate a high-temperature flame. This process is widely used for welding, brazing and cutting applications, particularly in maintenance, repair and manufacturing environments.
