Ball iron water check valve is a type of valve used in pipeline systems, whose main function is to prevent the medium from flowing back in the pipeline, while protecting the pump and pipeline system from damage caused by water hammer. The ductile iron material provides excellent strength and corrosion resistance, making it suitable for various working conditions.

The working principle of ductile iron non return valve is based on the pressure difference generated by the flow of the medium. When the medium flows forward, the valve opens, allowing the fluid to pass through. When the medium attempts to flow in reverse, the ball inside the valve is pushed towards the valve seat under the pressure of the medium, thereby closing the valve and preventing the medium from flowing back. This design ensures automatic operation of the valve without the need for an external power source.

The advantages of ductile iron non return check valve include:

1. Compact structure: Compared with traditional check valves, ductile iron check valves have a shorter structural length, smaller volume, lighter weight, and are easy to install and maintain.

2. Good sealing performance: using rubber foreskin ball flaps to provide good sealing effect and reduce leakage.

3. Silencing off: When turned off, it can reduce water hammer waves, lower noise, and protect the pipeline system.

4. Wear resistance: The adhesive layer of the sphere has good elasticity and wear resistance, extending the service life of the valve.

5. Strong applicability: It can be used for various media such as cold water, hot water, industrial and domestic sewage, and is suitable for horizontal or vertical installation.

6. Reduce water hammer effect: The design of quick closing helps to reduce water hammer phenomenon and protect the pipeline system.

7. Easy maintenance: fewer parts, easy disassembly, and reduced maintenance costs.

Therefore, due to the high temperature, high pressure, and corrosive environment, ductile iron check valve 8 inch is widely used in the petrochemical industry to prevent medium backflow and ensure the safety and stability of the production process. In the inlet system and feedwater system of the steam turbine, ductile iron check valves can also prevent reverse flow of steam and feedwater, protecting the normal operation of the unit. Other industries include municipal water supply and drainage systems, chemical and pharmaceutical industries, especially in the environmental water treatment industry. In water treatment systems, ductile iron check valves can effectively prevent sewage from flowing back and ensure water quality safety.
