Duckbill valves are a type of non-mechanical check valve. They require no maintenance and do not slam when closed. Their non-mechanical design also prevents backflow. However, when fitting one into a pipe, you have to make sure that the flange is matched to the valve’s flange.
Duckbill valves are non-mechanical
Duckbill check valves are non-metal valves that rely on a flexible rubber diaphragm to prevent backflow. They work well in water supply systems and are suitable for seawater, raw water, and sewage. They also have various end flanges and can be used for a variety of pipes, including steel, PVC, and cement.
They require no maintenance
Rubber duckbill check valves are an efficient and cost-effective way to control back pressure in systems. They do not require any maintenance and are easy to install and operate. They also provide quiet operation and low opening pressure. There are many different styles available to meet different requirements.
They do not slam when closed
Rubber duckbill check valves do not come with the inherent slamming characteristics of swing/flap check valves. This https://evrproducts.com/products/rubber-expansion-joints/ is a benefit when you need to cope with water hammer. The rubber has inherent flexibility that allows it to flex when pressure is applied. In addition, rubber duckbill check valves are very durable and have excellent pressure and corrosion resistance.
They prevent backflow
Rubber Duckbill Check Valves are an effective solution for preventing backflow from water systems. These valves are capable of handling large obstructions and provide trouble-free backflow prevention. Their unique design includes an outer layer that repels marine organisms.
They are easily incorporated and assembled into a wide variety of devices
Rubber duckbill check valves are a simple and inexpensive way to control backpressure. As passive flow through devices, they do not need external power or maintenance. They are also extremely easy to incorporate and assemble into a variety of devices. They work by using differential pressure and flow rate to prevent backflow. A minimum amount of pressure is required to open the valve.
They are a cost-effective solution for controlling back pressures
Rubber duckbill check valves are used for a variety of applications, including sewage treatment plants, wastewater outfalls, tidal operations, and industrial process piping. Their unique design ensures a high degree of flow control with minimal pressure drop. This type of check valve also requires minimal maintenance and offers a low opening pressure.
