Product Description
Product Overview
The EN 1092-2 Flanged Duckbill Blowdown Check Valve is a flexible neoprene rubber check valve designed for efficient fluid control in industrial, agricultural, and municipal applications. This maintenance-free valve prevents backflow of sewage and floodwater while ensuring reliable operation in demanding environments.
Working Principle
The duckbill valve operates through its unique design where the rubber canopy automatically adjusts the opening size based on flow rate or pressure changes. When fluid flow stops, the valve closes tightly to prevent backflow and odor transmission. With no moving components, it eliminates jamming risks and ensures maintenance-free operation.
Key Features & Benefits
- Resilient neoprene rubber construction requiring zero maintenance
- Prevents flooding and sewage backflow into street sewers and basements
- Acts as water seal device to isolate odors from outdoor inspection wells
- Freeze-resistant operation with minimal head loss during opening/closing
- Long service life with excellent sealing performance and anti-odor back features
- Effective prevention of backflow and sediment formation during drainage
- Superior diffusion performance with fast jet speed and energy efficiency
- Cushioning, sound damping, and corrosion-resistant characteristics
