Cast Iron/Ductile Iron Flap Valve

Ductile iron flap valves are designed to allow forward flow while preventing backflow in a variety of applications, including water and sewage systems. These valves are constructed with high-quality ductile iron, providing superior durability and resilience. 

Their design includes a rubber sealing element, allowing the valve to tightly close when water flow stops, preventing backflow. The unique design of the ductile iron flap valve provides a low maintenance operation with no moving parts within the valve. This translates to cost savings as well as increased efficiency. 

Ductile iron flap valves come in a range of sizes to suit different applications. They are available in both wafer and flanged versions to easily match piping systems. The valves are available in a variety of pressure classes (PN6, PN10, PN16, PN25, and PN40) ensuring compatibility with any system requirements. 

The installation process for these valves is simple, thanks to their wafer or flanged ends. This enables quick and convenient installation on to piping systems without the need for additional specialized tools. The valves come in standard epoxy coated finish, which enhances corrosion resistance as well as providing an aesthetically pleasing appearance. 

Overall, the ductile iron flap valve provides an excellent solution for controlling and preventing backflow in various applications. Their durability, easy installation, and low maintenance make them ideal for use in a range of industries, including but not limited to water and sewage systems.
