The Curved Bill Rubber Duckbill Check Valve

The Curved Bill rubber duckbill check valve is a highly effective, cost-efficient choice for sewer and drainage applications. Its main features include low head loss, maximum flow rate, and easy installation. Learn more about this check valve and why it is so effective! Buying the right valve for your particular situation is crucial to a successful sewer installation.

Low head loss

In line rubber duckbill check valves are the solution for zero backflow, thanks to their low head loss. These fully passive flow devices do not require manual assistance, power or maintenance. This makes them ideal for municipal applications where zero backflow is required. The TF-1 valves have a higher bill height to increase their effective open area, which lowers headloss and improves hydraulic performance.

Duckbill check valves are often made of rubber or silicone. The flexible rubber diaphragm of these valves compresses around trapped solids and provides a tight seal during backflow operations. Low cracking pressure and flexibility of these valves make them suitable for small bore and low-pressure applications. Moreover, these valves are highly reliable and don’t rust.

Maximum flow rate

Duckbill Check Valves are a popular choice for sewage systems. Featuring a flexible sleeve design and fabric-reinforced elastomer materials, these valves provide maximum flow with minimal pressure drop. They are a proven solution for preventing back flow and have been used for over 100 years. Among the features that set them apart is their superior seal. They are resistant to corrosion, rust and UV rays.

Another great feature of a duckbill valve is its ease of installation. These passive valves can easily be incorporated into a variety of devices without requiring complicated assembly processes or surface finish of mating seats.

Easy installation

A rubber duckbill check valve is a convenient and inexpensive plumbing part that is easy to install. The rubber materials used in these valves are more durable than metal check valves, and they have a long service life. In addition, they have a low opening pressure, which can reduce head loss. They are also convenient to use and install and can be repaired when needed.

These valves are available all over Australia and can be installed in just minutes. The slip-on variety can be installed directly on the pipe, while the flanged type can be pinned to the headwall. When fitting the flanged valve, it is important to make sure the flange specification of the valve and the pipe match. To install a flanged rubber duckbill check valve, make sure to install it in a vertical position with the opening facing up.
