Anti-backflow device XL-T (FS) rubber drain check valve duckbill valve

Backflow device (type rubber sewage check valve, duckbill valve
Product introduction
Type rubber sewage check valve, (called duckbill-shaped flexible check valve in Spain, called duckbill-shaped rubber flat-bill valve in the United States) On the basis of the production of Spanish Valve Company and American Red Valve Company, we conduct a comprehensive, exemplary and revolutionary redesign. We are also committed to continuously improving the (duckbill-shaped flexible check valve) rubber sewage check valve, so as to make the strength of the valve , toughness and sealing are greatly improved. The valve does not have any movable components and does not require any maintenance. The valve can be matched with straight pipes, flange pipes, cement pipes, and fiberglass pipes. This valve replaces the slamming check valve and completely solves the problem of slamming doors. It is easy to be blocked by sand, silt, stones, vegetation and marine life. Its advantages are as follows
It has strong workability and can provide efficient, quiet and powerful work without any external energy device, reducing operating costs.
Suitable for general working conditions and special working conditions with abrasive or corrosive media, such as sewage, sludge, mud, etc. The unique design features allow solid particles to pass through the valve smoothly, and can even be wrapped by its own flexibility. to ensure sealing.
The anti-backflow and backflow effect is good, and the elasticity of the rubber itself and the effect of reverse back pressure are used to ensure reliable sealing, especially the new curved valve mouth, which further increases the sealing performance and reduces the amount of heavy leakage or no leakage. Leakage phenomenon.
Opening and closing are realized naturally through the internal and external pressure difference during operation. It is an excellent choice for sewage discharge systems and pipe network systems.
The type rubber sewage discharge check valve is made of all rubber material , simple structure, no corrosion, no mechanical parts, will not cause siltation or impurity stuck, reducing maintenance costs.
