Duckbill Drain Valve

Our Duckbill Drain Valve Type XH41 is made for city waste water, storm water discharge, and flood control systems. We use it in big drain pipes, pump station outlets, and waste water treatment plants. We have been making pipe parts for over 20 years. This duckbill drain valve type xh41 stops backflow, prevents flooding, does not clog, and makes no noise. It keeps city drainage safe. We use natural rubber, neoprene, or EPDM for the valve body. We add high-strength polyester fiber reinforcement. The tensile strength is over 12MPa. The flanges are carbon steel or stainless steel. They fit GB, ANSI, and DIN standards.

This thing works from -30℃ to 120℃. It handles pressures from PN6 to PN16. Each duckbill drain valve type xh41 gets a seal test at 1.5 times the rated pressure. When water flows forward, it opens by itself. Flow resistance is very low and drainage is smooth. When water pushes back, it closes by itself. This stops waste water and sea water from going backward. It also blocks bad smells. The full rubber streamlined shape does not catch debris or clog. No upkeep and no manual work needed. The flange connection is strong and seals well. It works for big sizes and high pressure drainage systems. It resists corrosion well. It works for waste water, sea water, and chemical waste water. Our factory is 10,000 square meters with 50 workers. We check every unit before shipping. We give a 24-month warranty.

Every drainage project has different flange standards. So you can change this duckbill drain valve type xh41 to your needs. Tell us your material, pressure, and flange standard.
