The duckbill check valve is a type of check valve

The duckbill check valve is a type of check valve, usually made of rubber or synthetic elastomer. It is shaped like a duck’s beak and contains 2 flaps to prevent backflow of fluid. It is commonly used in medical applications to prevent contamination caused by backflow.


The duckbill check valve is a backflow prevention valve. Its special design resembles that of a duck’s bill and it works to prevent backflow in both the positive and negative directions. It is suitable for applications in sewage, piping, and drainage systems. These valves are commonly made of rubber or food grade silicone.

A duckbill check valve is a low-cost, low-maintenance component that can last up to 50 years. Compared with a mechanical check valve, which needs replacement after just a decade, a rubber duckbill valve is less likely to develop damage during transportation and installation. However, it is important to keep these valves away from excessive heat sources and high temperatures to maintain the proper function of the device.


The materials for duckbill check valve are largely determined by theĀ look these up application and the pressure it has to withstand. These valves are often used in sewer interceptors, mine tailing systems, and outfall lines. Their multi-layer sleeve design offers abrasion and corrosion resistance. Secondary services for duckbill valves include testing, auditing, and maintenance. In addition, duckbill valves can be assembled easily.

One manufacturer of check valves is Qosina, which offers a complete line of check valves. One particular duckbill check valve, part #80057, is an in-line check valve with a 0.130-inch-OD tubing port at each end. It is designed for applications with back pressure and is available in both polycarbonate and silicone.


Duckbill check valves are used in different applications and are safe for both water and CO2. They are made with synthetic rubber and fluorosilicone materials. These materials have special properties and can be used in a variety of applications. Because of their safety, they are suitable for use in machine parts and automobile accessories.

Manufacturers of duckbill check valves have the necessary expertise to provide the best solution for your application. Their products are highly reliable and have a long life expectancy of 35-50 years. These valves are widely used to prevent backflow from wastewater treatment plants and protect against sewer gas and odors.


Duckbill check valves are ideal for large obstructions and guarantee trouble-free backflow prevention. The rubber construction of duckbill valves guarantees tight sealing, backflow prevention, and low opening pressure. They are also durable, able to seal despite high pressure, and are constructed with outer layers that repel marine organisms.

Duckbill check valves are versatile and are easily integrated into a variety of devices. Due to their simple construction, they are easy to manufacture. They are also easy to assemble. This means that complex processes and surface finish are not required.


A duckbill check valve is a type of inline check valve. This type of valve is made of rubber and is designed to fit inside a pipe. In order to install one, you must access the inside of the pipe and the outside diameter must be smaller than the inside diameter. When installing a duckbill check valve, you must not over-tighten it.

Duckbill valves can last for 30 to 50 years. This makes them a good choice for many different applications. Mechanical check valves, on the other hand, typically require replacement after less than a decade of service. As such, you should carefully consider the type of check valve you need to install and the installation process to ensure that it will work well.
