Rubber Duckbill Check Valves are a cost-effective and reliable solution for back pressure management in sewage and stormwater piping systems. They are manufactured from high-quality engineering elastomers, and can seal around suspended solids and debris. These valves can be used to prevent backflow and to control flow direction. They can be installed in many different ways, and offer a low maintenance alternative to conventional flap type check valves. They also offer trouble-free operation, and require no manual assistance.
Duckbill check valves are available in a variety of styles and materials. They can be made from food grade silicone or medical grade material. They can be used in sewage, raw water, and seawater. They are available in three basic types: Slip On, Clamp, and Flanged.
These valves have no moving parts and are easy to install. They can be attached to plain ended pipes, or fitted over an existing pipe. They are commonly used in drainage systems, lifting pump stations, and submerged aeration systems. They are environmentally friendly, and are designed to replace traditional swing gate check valves.
Rubber Duckbill Check Valves are available in various shapes and sizes, and are designed to handle large obstructions in a wide range of municipally pumped media. They have a slit on the end of the valve to prevent forward flow and backflow. When the flow rate reaches a certain level, the valve will open, and the slit will close. The slit is cut using a die-cutting tool that has an angle of 45 to 55 degrees in the rubber duckbill check valve end. This tool will not rip or remove the material, and will leave a clean slit in the end of the valve.
Duckbill check valves are also available in a variety of materials, including fluorosilicone, NBR, and EPDM. The outer layers are usually made to repel marine organisms, while the inner surface is smooth and flat. This makes them ideal for use in tidal, ocean, and drainage operations. They are also less likely to freeze, and can flex around objects in a water stream. They can also be manufactured to fit into a variety of pipes, including steel, PVC, and cement pipes.
Duckbill check valves are generally easy to install and have a long service life. They require no power or outside support, and are a quiet, effective way to maintain back pressure. They are not susceptible to mechanical wear and can be used in many applications, including in wastewater treatment and drainage systems, sewage, and stormwater piping systems. The cost of a rubber duckbill check valve is lower than that of a traditional flap gate check valve. They are suitable for most applications, including industrial process piping systems, sewage treatment plants, and outfalls.
If you are in the market for a new check valve, you may want to consider the Flexicraft Rubber Duckbill check valves. They are made to replace traditional flap type check valves, and they offer quiet, efficient, and economical operation. They are available in a wide range of styles, and come with a low opening pressure.
