Rotarex Joins Gifen to Strengthen its Commitment to The Nuclear Industry

Strengthening Collaboration Within the French Nuclear Ecosystem

GIFEN brings together key stakeholders across the French nuclear value chain, promoting industrial excellence, innovation, and collaboration. Rotarex’s membership reflects its strategic commitment to contributing to a strong and competitive nuclear industry in France and internationally.

With nuclear energy playing a critical role in delivering low-carbon power and strengthening energy independence, Rotarex continues to provide high-integrity components designed to meet the strictest safety and qualification standards.

High-Integrity Bellows Valves for Nuclear Applications

Rotarex designs and manufactures bellows valves for civil nuclear, defense, and aerospace applications, with production based in France.

Nuclear environments impose extreme constraints in terms of safety, sealing performance, pressure, temperature, and material compatibility. Rotarex bellows valves are engineered to meet these challenges, including:

• Zero-leak tolerance with certified helium leak testing
• Leak tightness ≤ 1×10⁻¹⁰ Pa·m³/s to the atmosphere
• High-pressure resistance up to 240 bar (400 bar for certain models)
• Extreme temperature range from -270°C to +250°C (+800°C for certain models)
• Compatibility with demanding media such as UF₄, UF₆, deuterium, tritium, fluorinated and chlorinated gases
• Advanced materials including Stainless Steel, Inconel, Monel, and Hastelloy

Drawing on decades of expertise in gas control technologies, Rotarex develops tailor-made valve solutions, from special geometries to advanced materials and sensor integration, fully adapted to each customer’s process requirements and qualification standards.

Serving Critical Nuclear Applications

Rotarex solutions are deployed across key nuclear segments, including:

• Uranium conversion and enrichment
• Fuel fabrication and reprocessing
• Containment systems and radioactive isotopes
• Nuclear propulsion and research programs (including ILL, ITER, CEA, CNRS)
• Small Modular Reactors & Advanced Modular Reactors (SMR/AMR)

Through integrated engineering and manufacturing capabilities, Rotarex ensures safety, reliability, and long-term performance in environments where failure is not an option.

A Strategic Step Forward

Membership in GIFEN strengthens Rotarex’s position within the nuclear ecosystem and supports its ambition to contribute to future nuclear projects in France and worldwide, with solutions designed and manufactured to the highest industry standards.
