CN Clean-Break

Advantages of the CN Series

The CN series clean-break couplings, engineered by Walther-Präzision, provide an advanced solution for industries requiring efficient and safe fluid transfer systems.

These couplings are particularly valuable in chemical processing, logistics and other sectors where contamination-free operation is critical.

By combining robust engineering with precise functionality, the CN series delivers exceptional reliability, safety and performance in demanding environments.

Key Features of the CN Series
  • Clean-Break Technology

At the core of the CN series is its innovative clean-break technology, designed to minimize fluid leakage during coupling and disconnection – even when handling long, pressurized hose lines. These couplings can operate effectively with residual pressures up to 8 bar, ensuring safe, leak-free operation that protects both the workplace and the environment.

  • Compact and Ergonomic Design

The CN series features a space-saving design, allowing installation in tight work areas without compromising usability. For example, the CN-025 variant can be operated without a ring handle due to its low actuation forces. This ergonomic advantage simplifies handling and reduces operator physical exertion.

  • Exceptional Flow Characteristics

Optimized internal geometry delivers excellent flow rates, ensuring efficient fluid transfer, meeting the demands of high-volume applications and reducing the energy required to maintain operation.

The CN series is manufactured from premium-grade stainless steel (AISI 316 Ti), providing durability and corrosion resistance under harsh conditions. Additional material options can be customized to meet specific operational requirements.

Sealing elements are made from high-quality elastomers and are available in different grades to accommodate temperatures from -20°C to 100°C. For extreme conditions, versions capable of up to 200°C are also available.

  • Chemical Industry Applications

The CN series is primarily designed for chemical loading stations, such as trucks and ships, excelling in the transport of hazardous or sensitive liquids. The ability to connect and disconnect without loss of medium is essential for maintaining a clean and safe working environment.

  • Other Industrial Applications

Beyond chemical processing, CN couplings are used in industries such as liquid food processing and other sectors where contamination-free fluid handling is required.

  • Suitable for Vacuum: The CN series is compatible with vacuum systems when coupled, expanding its range of applications.
  • Optional Accessories: A variety of accessories are available to enhance functionality, including protective caps and plugs, electronic systems for lock-status verification and mechanical coding for added security. Couplings can also be locked to prevent unauthorized access.
  • Emergency Release Options: For critical applications requiring rapid disconnection, the series includes quick emergency-release couplings, such as the CT-019 type, ensuring safety during unexpected pressure peaks or operational deviations.
  • Technical Excellence in Design: The clean-break mechanism uses a bayonet locking system, a robust design that ensures secure connections and reliable operation under pressure. Its leak-free design minimizes fluid loss per disconnect cycle, enhancing both efficiency and environmental compliance. All couplings are thoroughly tested at room temperature with water to validate their performance.

Conclusion

The CN series clean-break couplings from Walther-Präzision are an excellent choice for industries demanding high reliability, safety and operational efficiency.

With innovative features, outstanding flow rates, and a versatile design, they meet the stringent requirements of modern industrial environments. Whether transporting chemical liquids or handling specialized applications, these couplings provide a robust, effective solution for clean and safe fluid transfer.
