Product Introduction
The main structure of Neway flexible check valve consists of the body, bonnet and disc. Disc is fully covered with special rubber. Under the combined action of the elastic disc and the reverse-flow water, it closes quickly, reducing the speed of backflow, thereby minimizing the impact force when the disc reseats and the water hammer. Seat is at a 45-degree angle to the center of the body, which makes it less likely to accumulate debris. Closing stroke is short, effectively reducing the water hammer phenomenon. It features excellent sealing performance, adopts full-flow design, and has low resistance loss and is not prone to accumulation of debris. Can be widely applied to water supply systems, drainage systems, sewage treatment systems, etc., and is used to prevent the backflow of media.
