Duckbill check valves are important components of sewage treatment facilities. They help to control back pressure, and they prevent the backflow of debris, mud, and silt. Additionally, they are resistant to corrosion and mechanical wear. Listed below are some of the reasons why duckbill check valves are a great choice for your sewer system.
Duckbill check valves are used to control back pressure in sewage treatment plants
Duckbill check valves are an efficient back pressure control device used in wastewater treatment plants. They have a design that is very adaptable to various applications. Some duckbill models are designed for sewer system control and some are specifically used in manholes or end-of-pipe outfalls. These valves are also widely used in storm water control and backflow prevention applications.
Duckbill check valves are designed to control back pressure by reacting to discrepancies in pressure. When upstream water force is high, the valve body has a high differential pressure. When back-flowing water is present, the differential pressure between upstream and downstream water becomes low and the duckbill elastomer valve flexes closed, sealing debris out.
They prevent the backflow of mud, silt, and debris
Rubber duckbill check valves are used to prevent the backflow of mud, sill, and debris into waterways. The duckbill valve uses a flexible rubber diaphragm that creates a valve that closes when positive pressure is applied to it. This valve can be used in a variety of applications, including sewage and municipal flooding.
Rubber Duckbill Check Valves have a very high level of reliability. Their design can handle the toughest obstructions. With rubber duckbill check valve a tight seal, they guarantee trouble-free backflow prevention. They use the best engineering elastomers and are coated on both sides to repel marine organisms.
They are corrosion resistant
Rubber duckbill check valves are a highly effective and efficient way to manage backpressure in water and wastewater systems. Because they are passive flow-through devices, they require no external power or maintenance. They are also incredibly flexible, ensuring the right amount of flow. In addition, they have very low opening pressures and are extremely quiet in operation. Rubber duckbill check valves are available in a number of styles to meet specific needs.
The design of Rubber Duckbill Check Valves prevents floating objects from clogging the valve and causing it to fail. These valves can handle a wide range of solids, including corrosive substances. They also guarantee trouble-free backflow prevention by sealing around suspended or trapped solids. They are also corrosion-resistant, thanks to their elastomeric, fire-retardant construction.
They do not suffer from mechanical wear
A duckbill check valve is made of rubber and is highly resistant to mechanical wear. It can last up to 50 years. It is also resistant to water hammer. This type of check valve is also good for sewage plants. This type of check valve is not suitable for drinking water because sludge and debris can clog the metal hinges and prevent it from closing. The flow rate of a duckbill valve is usually in gallons per minute and hours or litres per second.
Another great feature of a duckbill check valve is its low maintenance. It does not require any external power or maintenance. It also requires no manual help. This means that it does not need to be replaced frequently. Rubber duckbill check valves also do not suffer from mechanical wear, which can affect check valves made from other materials.
