The rubber duckbill check valve is a type of inline check valve. It is designed with a flange that acts as a gasket between two mating flanges. When fitting this valve, you should make sure that it is tightened correctly around the mating flanges in the pattern specified. This type of valve is available across Australia.

Low headloss

Low headloss with rubber duckbill in-line check valves are an excellent choice for municipalities that need to ensure that water will not back up into the pipe. These valves have been specifically designed for this purpose and are favored by municipalities for a number of reasons. For example, they provide rapid dispersion of head pressures and are highly resistant to backflow. They also have a low cracking pressure, reducing the possibility of upstream flooding.

Rubber duckbill check valves are reliable and affordable alternatives to flapgate check valves. They do not require maintenance and require little or no assistance to install and operate. They are ideal for low-lying areas and offer quiet operation.

Environmentally friendly

Duckbill valves are a type of check valve that has many advantages over other types. First of all, they don’t have any mechanical or moving parts, which can cause noise. They are also manually operated, which means they don’t require electricity to work. Another advantage of duckbill valves is their low cost. They also offer longer service life than metal check valves.

The design of the duckbill check valve allows it to withstand high water pressures and large obstructions, which guarantees a completely trouble-free backflow prevention. TheĀ valves are made of durable, elastomeric material and have a tight seal to repel floating objects. Furthermore, they are resistant to Ozone light and resist the growth of sea weed and barnacles.


A rubber duckbill check valve is a type of check valve that prevents liquid from passing through the valve. When reverse pressure is applied, the valve tightens to prevent passage of liquid. These valves typically have two sections, but they can also have three sections. They are similar in design to the mitral valve in the human heart.

Rubber duckbill check valves are a reliable, cost-effective way to control back pressure in pipes. They are highly efficient and require minimal maintenance. In addition to their excellent backflow prevention, these valves also offer low opening pressure and quiet operation. They are available in a wide range of styles and are designed to replace flap type check valves.

Available in various elastomeric materials

Elastomeric materials are used for a wide variety of industrial applications. They are often used in hydraulic applications and are able to withstand high torques and high dynamic forces. Other uses for elastomeric materials include tyre inner tubes, valves, seals, and pharmaceutical goods.

Elastomeric materials are made from long chains of polymer molecules that cross-link during the curing process. This feature of the elastomer is responsible for its elasticity. They can extend or contract by five to seven hundred percent and regain their original shape when stress is removed.

Easy to install

The rubber duckbill check valve is an inline check valve. This type of valve is a common choice for many applications, and is easy to install. Its flange acts as a gasket between the valve and the mating flange. It is important to be careful not to overtighten the flange clamps, and to ensure that the valve is correctly positioned. The rubber duckbill check valve can be purchased from a variety of places across Australia.

Rubber duckbill check valves are a cost-effective and efficient way to control back pressure. These valves are easy to install and require very little maintenance. They also offer low opening pressure and are extremely quiet. These valves are available in a variety of styles and are designed to replace flap type check valves.
