Opis produktu

Flange Type Sewage Rubber Duckbill Check Valve Clamp Connected Bellows Piping

A Flange Type Sewage Rubber Duckbill Check Valve with Clamp-Connected Bellows Piping is a robust, maintenance-free backflow prevention solution designed for sewage, drainage, and industrial wastewater systems. The flange-end duckbill check valve allows forward flow with minimal pressure and automatically seals when reverse pressure occurs, ensuring reliable one-way operation. Integrated with a clamp-connected rubber bellows section, the unit effectively absorbs vibration, reduces noise, and compensates for thermal expansion, misalignment, and pipe movement. This combined structure offers excellent corrosion resistance, long service life, and easy installation, making it ideal for municipal engineering, treatment plants, pump stations, and harsh fluid-handling environments where flexibility and reliable backflow control are essential.
