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: Why can the ball check valve be used for sewage?

Ball check valves are commonly used in sewage and wastewater treatment applications because they offer several advantages that make them well-suited for these environments. Here are a few reasons why ball check valves can be used for sewage:

• Non-clogging design: Ball check valves have a simple, non-clogging design that allows them to handle solids and debris commonly found in sewage and wastewater. The ball moves freely within the valve body, reducing the risk of clogs and blockages.
• Tight shutoff: Ball check valves provide a tight shutoff, preventing backflow and ensuring that sewage flows in only one direction. This is important in wastewater treatment facilities to prevent contamination and maintain a safe environment.
• Low maintenance: Ball check valves have a simple design with fewer moving parts than other types of check valves, which reduces the need for maintenance and lowers operating costs.
