A duckbill check valve is a check valve that has flaps on either side that can be opened to allow or prevent backflow. They are commonly used in medical applications to prevent contamination due to backflow. These valves are designed to withstand high pressure and temperature. This valve is made from rubber or synthetic elastomer.
The Series 37 Inline Check Valve provides a revolutionary solution for backflow prevention. This new design allows the valve to be inserted into the downstream pipe between two flanges, reducing the need for a valve body. The Series 37’s face-to-face dimension matches the thickness of the flange. This makes the valve ideal for applications with limited space. It also offers superior sealing compared to other styles of Tideflex(r) Check Valves.
These duckbill-shaped elastomer check valves are frequently used on stormwater outfalls and wastewater effluent diffusion systems to prevent baekflow and sea water intrusion. They feature integrated elastomeric flanges and are supplied with retaining rings for installation.
CPI-IN Check Valves
The Duckbill CPI-IN Check Vavles are ideal for use in a wide variety of applications. These check valves are self-sealing and noiseless, and they are corrosion-resistant. They can be used in applications such as water-mixing systems, waste-water treatment plants, and storm-water outlets.
The CPI-IN Check Valve is designed to be installed inside a pipe and is able to handle corrosive and abrasive materials. Because of its flexible design, it is able to surround trapped solids to maintain a seal. It is also built with fire-retardant elastomeric construction, which makes it non-corrosive and easy to maintain.
Rubber duckbill check valves
Rubber duckbill check valves are used to prevent backflow and leakage of water. They are primarily used for sewage discharge systems. These valves are easy to install and can be used on a variety of different systems. Their complete rubber design offers corrosion resistance, low opening pressure, and long service life.
Rubber duckbill check valves can be installed either by flanged or slip-on configurations. In either case, the flanges must match. When installing a flanged valve, it is necessary to check the specifications of both the pipe and the valve. Ensure the flanges fit tightly and that the outlet of the see page check valve is vertically installed. If the valve is installed improperly, the opening could rotate before the fasteners are installed.
Swing check valves
Duckbill check valves are used in wet walls, sewer interceptors, and mine tailing systems. They feature multi-layered sleeve construction and are abrasion and corrosion resistant. A duckbill valve has a large sealing area and is capable of withstand up to 15 meters of back pressure.
They can last from thirty to fifty years. This is much longer than mechanical check valves, which must be replaced within a decade of operation. Choosing the correct valve for your application requires careful consideration and careful selection of its materials. Typically, duckbill valves are made of elastomeric material, which is fire-resistant and resists corrosion.
Diaphragm check valves
Duckbill Check Valves are available in various designs, sizes, and materials. They can be used in air pumps or gas pumps and offer a tighter seal and faster response time. Typically, duckbill check valves have two or three sections and are similar to the mitral valve of the human heart.
Duckbill valves can last between 30 and 50 years. They are also self-sealing, corrosion-resistant, and quiet. Their highly flexible diaphragms offer a tight seal for backflow prevention.
