Applications

Ball check valves are commonly used in applications where low flow resistance and reliable backflow prevention are necessary, such as in water treatment plants, pumping systems, and process piping systems. They are often used in situations where the fluid needs to flow in only one direction, such as in fuel lines, chemical processing systems, and air compressors.

Tips: What is a ductile iron ball check valve?

A ductile iron ball check valve is a type of check valve made from ductile iron, which is known for its excellent strength, ductility, and impact resistance. The valve features a spherical ball that moves freely inside the valve body. When fluid flows in the correct direction, the pressure pushes the ball away from the valve seat, allowing the fluid to pass through. When the flow stops or reverses, the ball returns to its seat, effectively sealing the valve to prevent backflow.

Ductile iron provides several advantages for ball check valves. It offers superior mechanical properties compared to traditional cast iron, including higher tensile strength, improved toughness, and better resistance to wear and tear. This makes ductile iron ball check valves suitable for a wide range of demanding applications, including water and wastewater treatment, industrial processes, and certain chemical applications.

These valves are designed to handle various types of fluids, including clean or dirty water, slurries, and other non-corrosive fluids. Their robust construction ensures durability and longevity, even in harsh operating conditions. Additionally, ductile iron ball check valves are relatively low maintenance, providing reliable and efficient operation with minimal servicing requirements. This combination of material strength and functional design makes them a popular choice in many industrial and municipal systems.
