Check valve application

Check valve highly versatile and highly durable, since they do not require a power source or any exterior action to operate. The elastomer bill design is low-maintenance, rust-free, and can be highly responsive to very subtle pressure changes across line fluid. The design and structure of duckbill check valves make them widely applicable in pressured fluid environments.

Since this spring check valve responded to subtle pressure differentials, they proved to be an excellent solution in preventing salt water backflow. Turbulent weather proved to be a problem for this store. During periods of heavy rain and high tides, the waters of Tampa Bay reverse-flowed into the pond, causing the vegetation to wither and die. The pond was fitted with three 36-inch check valve.

Check valve can be used in a variety of wastewater, stormwater, and backflow prevention applications. One excellent case study involved a large, well-known retail store in St. Petersburg, FL. The pond was decorated with fresh water vegetation, as are many retention ponds in this part of the American Southeast. This store had a large retention pond, or man-made pond designed to collect rainwater.

Check valve is suitable for a variety of other applications, as well. Some models are ideal for manhole and end-of-pipe outfall installations. Others are used for stormwater control, as the retail store case study illustrates; or, for wastewater treatment applications. Certain duckbill models can be used in industrial applications, such as corrosive slurry handling, caustic chemical applications, and high-temperature chemical reactions. Still others are installed for the purposes of sewer system control and sewer backflow prevention.
