SN-25 Cartridge - 25mm Range


1. Improved performance: 25mm cartridges are typically more sensitive to tough conditions, so we developed a new 25mm valve improving the technical specifications from previous versions to achieve the best performance.
   • +30% flow rate increase
   • +20% smoothness operation torque
   • -50% noise reduction
2. More endurance: The application of new technologies inside our cartridges has extended SN-25 endurance:
   • 2 x ASME / 2 x EN-817 life cycle
   • Improved plastic material robustness
   • +50% Increased torque resistance
   • +30% Increased flexion resistance
3. Tough construction for small faucet designs: The small size of SN-25 makes it specially suitable for slim design faucets, allowing the manufacturer to innovate with its design without giving up the high-performance and robustness of the product.
