• Optimized hydraulic performance
• Thanks to its low inertia design and limited stroke, the non-return valve closes quickly and without noise during a flow return, effectively reducing water hammer phenomena
• The internal design promotes smooth flow, making it possible to limit pressure losses while maintaining a very low coefficient of resistance
• The maximum opening position is obtained for a flow speed average of around 2 m/s
• The metal elements are made of stainless steel or ductile iron protected by an epoxy coating, ensuring excellent corrosion resistance
• The bronze ring reduces wear.
• The guiding devices are designed for long-lasting operation without the need for maintenance
• Compact design combined with reduced weight
• Directional marker integrated on the body to indicate the direction of movement of the fluid
• Installation possible in both horizontal and vertical positions
