A duckbill check valve is a type of valve that prevents seawater and sediment from entering the discharge pipe. It also facilitates flushing of the discharge pipe. Its construction can also allow for higher dilution in certain conditions. However, this type of valve is not suitable for all applications.

A duckbill check valve is an important piece of equipment for backflow prevention. It works by closing when the pressure outside exceeds the pressure in the pipeline and prevents backflow. They are commonly used in applications such as seawater, sewage, and raw water. A duckbill check valve can withstand up to 8 m of water pressure and is made of natural rubber material. A clamp-type duckbill check valve can be used on steel, cement, PVC, and corrugated pipes.

The material of a duckbill check valve is often chosen based on the application and the working environment. Common materials used in these valves are NBR, EPDM, and silicone. Different materials have different properties, and choosing the right material for your application is critical.

Flow control

A duckbill check valve is a popular choice for wastewater applications, particularly in municipal flooding applications. Its unique design features include corrosion resistance, a long service life, and quiet operation. As a result, duckbill valves are widely used in municipal and industrial settings.

Rubber duckbill check valves are elastometic, one-piece valves that are used to control the flow of liquid. They work by preventing the passage of water when they are under high pressure. The pressure needed to close the valve depends on the hardness of the material. These valves are available in a wide range of elastomer materials, including hydrocarbon-resistant fluorosilicone rubber, food-grade silicone, and Buna-N and Viton.

The main advantage of using a duckbill valve is its durability and longevity. The valve can withstand temperatures between -65°F and 250°F. Its fire-retardant elastomer construction means it does not rust or experience mechanical wear and tear. Hence, the valve can last for decades without needing to be replaced.

Environmental protection

A duckbill check valve is a popular option for wastewater systems. This try this website type of valve is made of elastomeric material and can handle large obstructions. They also provide trouble-free backflow prevention. Their construction is designed to resist rust and corrosion. They also prevent the buildup of marine organisms such as barnacles.

Rubber duckbill check valves are available all across Australia. Their ease of installation means that they can be incorporated into a wide variety of applications. These valves are also easy to assemble and do not require complicated assembly processes. They can be purchased from a plumbing store or online.

A rubber duckbill check valve is an environmentally friendly alternative to flap gate check valves. These valves have no moving parts and require no maintenance. They also have a long service life of 35 to 50 years. They are also great for stormwater drainage and backflow prevention. As a bonus, they do not block the flow of water when the gate is open.
