Nuclear Gas Control Solutions for Civil, Defense & Research Applications

Gas control plays a critical role in nuclear environments, where safety, reliability, and accuracy are essential at every stage of a project. Each nuclear facility presents unique technical and regulatory challenges that require solutions capable of managing, regulating, and securing gas flows within civil nuclear infrastructure, defense-related facilities, and advanced research laboratories, often under extreme operating conditions.

At Rotarex, we design and qualify custom valves engineered to meet the most demanding nuclear specifications. From single valve prototypes to fully qualified production series, Rotarex delivers nuclear-grade performance tailored to your precise requirements, ensuring long-term reliability, compliance, and confidence in safety-critical applications.

Nuclear Gas Management Challenges

Nuclear applications impose extreme constraints in terms of safety, sealing, and performance
Complex gas management processes involving radioactive, toxic, or cryogenic gases (e.g., UF₄, UF₆, deuterium, tritium) under high pressure and temperature conditions
Need for absolute containment and precise flow control to prevent leaks or cross-contamination
Strict qualification and certification standards requiring full material traceability, helium leak testing, and compliance with nuclear-grade specifications

Engineered for Safety, Reliability & Leak-Tight Performance

Proven expertise in high-integrity bellows valves engineered for nuclear gas management applications
Resistant to extreme temperatures ranging from -270°C to +250°C (-454°F to + 482°F) and high pressures up to 240 bar / 3480 psi (400 bar / 5800 psi for certain models)
Ultra-low leak rates down to 1×10^-10 Pa·m³/s
Constructed using nuclear-grade materials such as Stainless Steel, Inconel, Monel, and Hastelloy, selected for their mechanical strength and corrosion resistance

Applications Across Civil, Defense & Research Sectors

Civil nuclear infrastructure includes electricity generation, fuel handling, waste treatment, and safety systems within civil nuclear facilities. For these applications, it is important to have safe systems with containment gas management and emergency shutdown capabilities.

Civil Nuclear Infrastructure
Defense-related infrastructure requires gas systems with a high level of safety and reliability. In these extreme environments, it is essential to have resistant gas systems and high-integrity inline valves capable of maintaining leak-tight performance, precise control and fail-safe operation under pressure, vibration and shock.

Defense & Strategic Facilities
In research, flexibility and precision are essential criteria for the use of gases. Flow control and stability enable precise experimental setups and reliable engine testing, ensuring consistent operating conditions, accurate measurements, and reproducible results.
