low headloss in-line rubber duckbill check valve

A low headloss in-line rubber duckbill check valve is the perfect solution for sanitary and combined sewer overflows. It is also an excellent choice for storm water outfalls. A combined sewer is a type of sanitary system that collects surface runoff and sewage from several sources. Combined sewer overflows (CSO) are often a major problem for water pollution during CSO events. In such instances, untreated sewage from a sewage treatment plant is discharged into the environment.

Duckbill check valve

The duckbill check valve is a type of check valve that usually has two flaps. The flaps are designed to resemble the beak of a duck, which helps prevent contamination caused by backflow. These valves are commonly used in medical applications. They are also useful in controlling the flow of liquids in tanks and other closed systems.

Duckbill check valves can handle very large obstructions. They also guarantee trouble-free backflow prevention. Moreover, they are made of the finest engineering elastomers and have a special outer layer that repels marine organisms.

Environmentally friendly

An environmentally friendly rubber duckbill check valve is a perfect solution for backflow control. It can be used in wastewater systems where backflow is a concern, or where saltwater infiltration can cause problems. This valve is made of 100% rubber and has a long service life.

The design of a rubber duckbill check valve allows it to seal around large obstructions. This means that you can be sure that you will not experience any backflow problems. These valves also have special outer layers designed to keep marine organisms from getting inside the valve’s closing mechanism.


The report on the Global Economical Rubber Duckbill Check Valves Market studies the current market scenario and forecasts its future prospects. It includes detailed information on the competitive landscape and key industry trends. This report also outlines the market size and segmentation by type, application, and region. It also provides an in-depth analysis of key market players and their strategies.

A duckbill check valve works by preventing backflow by closing when the external pressure exceeds the pressure in the pipeline. Its advantages include a simple design and the fact that it’s made of rubber. This makes it remarkably long-lasting and reliable. Furthermore, it offers excellent corrosion and mechanical wear resistance, which make it a preferred choice for a wide range of applications. In addition, theĀ this hyperlink duckbill valve is suitable for a variety of materials, including steel, PVC, and cement pipes.

Easy to install

If you have to fit a check valve into a piping system and aren’t sure how to do it, you can always use an easy to install rubber duckbill check valve. Unlike other types of valves, the duckbill type has a flange that serves as a gasket between the two mating flanges. Simply tighten the flange around the pipe, but don’t over tighten it.

The advantages of rubber duckbill check valves over other check valve types include low maintenance requirements and excellent reliability. These valves are made of rubber, which is naturally resistant to corrosion and wear. These benefits are important when choosing a check valve for your application. Choosing the correct one is crucial to avoiding water hammer and reverse flow.
