    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: Why need a flanged ball check valve?

    Flanged ball check valves are commonly used in a wide range of applications to prevent backflow and ensure the flow of fluids in one direction. Here are a few reasons why you might need a flanged ball check valve:

    • Prevent backflow: Flanged ball check valves provide a tight seal, preventing fluids from flowing back into a system or process. This is important in applications where backflow can cause damage or contamination, such as in water and wastewater treatment facilities or industrial manufacturing processes.
    • Maintain pressure: Flanged ball check valves can help maintain consistent pressure within a system, preventing fluctuations that can cause damage or affect the performance of equipment.
    • Reduce energy consumption: Flanged ball check valves have a low-pressure drop, which can help reduce energy consumption in systems where fluid flow is critical. By reducing the resistance to flow, the valve can help maintain optimal flow rates while minimizing energy consumption.
    • Versatility: Flanged ball check valves can be used in a wide range of applications and environments, including in water and wastewater treatment facilities, chemical processing plants, and industrial manufacturing processes.
