Designed for nuclear-grade precision, this DN20 ball valve combines CU5MCUC nickel alloy’s radiation resistance with a robust two-piece flange end construction. The self-lubricating inconel seats provide zero leakage under cyclic pressure, while the alloy’s high melting point (1399°C) prevents deformation in primary coolant loops. Its seismic-proof design resists vibrations from turbine operations and LOCA scenarios, ensuring compliance with stringent nuclear safety codes. Ideal for small-bore instrumentation lines and secondary containment, it offers modular access for inspection without system shutdown, balancing safety with operational efficiency in PWR and SMR environments.

The split-body design allows field replacement of seats and ball without disconnecting pipelines, reducing downtime by 80% compared to welded valves in nuclear maintenance outages. This is vital for refueling cycles, where access to primary loop valves is limited by radiation zones. The design complies with ALARA (As Low As Reasonably Achievable) principles, minimizing worker exposure during inspections or component replacement.
Installation: The valve is designed for easy installation. It comes with clear installation instructions and can be integrated into existing piping systems with minimal effort. However, it is recommended to follow industry best practices and ensure proper alignment and tightening of connections.
Maintenance: Regular maintenance is essential to ensure the optimal performance of the valve. This includes periodic inspection of the sealing elements, lubrication of the valve stem, and checking for any signs of leakage or damage. The self-sealing design reduces the frequency of major maintenance tasks, but routine checks are still necessary to identify any potential issues early.
Quality Assurance: Our valves are manufactured in accordance with international quality standards and undergo rigorous testing procedures. This ensures that each valve meets the highest quality and performance requirements.
Technical Support: We provide comprehensive technical support to our customers. Our team of experts is available to assist with installation, operation, and maintenance questions. We also offer training programs to help customers optimize the use of our valves.
Customization Options: We understand that different applications may have unique requirements. Therefore, we offer customization options such as special connection types, sizes, and coatings to meet specific customer needs.
