A duckbill check valve is a type of flexible backflow preventer. It is made of rubber or synthetic elastomer and has 2 flaps, one in front and one in the back, that close and open in opposite directions. These valves are commonly used in medical applications to prevent backflow contamination.
Duckbill check valves are flexible backflow prevention devices with a beak-like design that allows forward flow and prevents backflow. They are suitable for many applications, including drain, sewer, and breast pump systems. They are made of food-grade silicone and rubber.
They are easy to install and can be integrated into a wide variety of devices. Due to their flexible sleeve design, they can withstand high temperatures, high pressure, and ocean waves. This ensures that they provide tight sealing and minimize pressure loss.
They require no maintenance
Check valves are a very useful tool in a variety of fluid flow environments. They prevent contamination by preventing waste water and debris from entering the system. Some industries that use these valves are water and wastewater treatment, chemical processing, and petroleum refining. They are also widely used in pipelines and power generation.
These valves are made of durable rubber that does not corrode. In addition, they can handle a wide range of temperatures. These features make duckbill valves ideal for applications requiring a high-volume delivery system. Other uses include high-volume intravenous fluid delivery sets, automotive fuel pumps, heart surgery tubing circuits, and soap dispensers. They can even be used as anti-siphoning valves in shower heads.
They allow solids to pass unhindered
Duckbill check valves are flexible, flow-sensitive valves. Their name comes from the shape of the flaps on the valve, which resemble the bill of a duck. When the flow is zero, the click here for info flaps are closed. When the flow is increased, the pressure on the flaps causes them to open.
The Duckbill check valve is designed to handle large obstructions in water. It can seal around suspended or trapped solids, and offers very low backflow protection. It also has an elastomeric construction that resists rust and corrosion.
They are environmentally friendly
The duckbill check valve is an environmentally friendly valve that is widely used in marine, industrial and municipal wastewater systems. Its flexible sleeve design and quality fabric-reinforced elastomer material are able to provide maximum flow with minimal pressure drop. These valves are highly effective in the sewage industry and have been used for over 100 years. Developed by Dutco Tennant, these valves are able to meet the regulatory requirements of the wastewater industry.
A variety of environmental factors play a role in determining which type of check valve is right for the job. For instance, the type of fluid to be managed will determine the type of valve. If the fluid is corrosive, then a flap check valve might not be suitable. Also, high temperatures can wear out a flap check valve. Thus, it is imperative to specify the proper valve materials for the temperature range of the operation. To prevent such issues, duckbill valves have a unique elastomeric construction that is resistant to rust.
