Ball Check Valves

The ball in a ball check valve requires roughly half the opening pressure of a swing check valve, and the line stays open without springs or other mechanical auxiliary components. When the flow stops, the valve ball returns to its seat and closes the pipeline. Because of its simple structure, a ball check valve is practically almost maintenance-free.

Ball check valves are available from us with either threaded or flanged connections. The size options are shown at the bottom of the page.

Ball check valves are available in many different materials. In water treatment applications, such as wastewater treatment, cast iron body, epoxy-coated ball check valves are often used, with the ball usually rubberized with NBR or alternatively EPDM. In industrial applications, a ball check valve is often made from acid-resistant stainless steel, for example to improve its chemical resistance. In this case, the surface material of the ball can also be FPM. With the most demanding chemicals, plastic-bodied ball check valves are used, such as valves made from PVC plastic.

A common application for a ball check valve is in wastewater pumping stations, where the liquid is usually dirty in one way or another and the purpose of the ball check valve is to prevent backflow from the pressure line into the pumping station tank when the wastewater pump is switched off. A ball check valve is also suitable for other pumping applications where liquid is transferred from a lower level to a higher level, and the liquid must not flow back into the starting basin or tank after pumping ends. The liquid can be dirty or clean. The pumping station installation is shown below:

OPEN

The submersible pump is running “ON”, and as the pumped medium flows, the ball in the ball check valve has moved aside, allowing free flow through the valve.

CLOSED

The pump is switched “OFF”, and the flow in the pipeline stops. This causes the ball in the ball check valve to return to its seat, preventing the liquid in the pressure line from flowing back into the pumping station.

The ball check valves in our selection are specifically designed to reduce maintenance needs and ensure long-lasting operation even in demanding conditions. A ball check valve has a self-cleaning structure designed so that the movement of the ball automatically removes deposits and impurities from the inner surface of the valve. This feature makes ball check valves an excellent choice for applications where dirty liquids or liquids containing solid particles are handled, such as wastewater or industrial process water.

The self-cleaning structure does not only reduce the need for maintenance, but also extends the service life of the valve and improves the operational reliability of the system. In traditional check valves, deposits and blockages can cause malfunctions, but ball check valves remain operational without regular maintenance measures. This reduces system downtime, which is especially important in industrial and municipal engineering applications where continuous operation is necessary.

Ball check valves are designed to provide low pressure loss, making them energy-efficient and high-performing components for different piping systems. Low pressure loss means that liquid flow remains optimal, and the system’s pumping capacity is not unnecessarily lost as the liquid passes through the valve.

This feature is especially important in applications where flow rate and energy efficiency matter, such as industrial processes and municipal water treatment. Low pressure loss also improves the overall performance of the system. When the flow remains steady and efficient, the system operates more reliably and under less strain. This reduces wear on pumps and other system components, extending their service life and reducing the need for maintenance.

A ball check valve is energy-efficient, which not only reduces operating costs but also lowers the environmental impact of the system. When the pumping system operates at optimal power, energy consumption decreases, which is a major benefit especially in large facilities where energy savings can be significant. This makes ball check valves both an economical and environmentally sustainable choice.

A ball check valve is easy to install in both horizontal and vertical pipelines, which makes it a flexible solution for many different systems. Its simple structure and compact size enable quick commissioning and operation without complicated adjustments. BPI-Chempump’s specialists help choose the right valve size and model to match the system’s needs and requirements precisely.

A ball check valve is especially suitable for wastewater treatment, pumping stations and other applications where liquids may contain impurities.

Ball check valves are usually made from cast iron, aluminum or stainless steel, and the balls may have rubber or plastic coatings.

A ball check valve is designed to cause very little pressure loss, which makes it efficient in different applications.

Ball check valves are usually simple to install in both horizontal and vertical installations, and they can be attached with either threads or flanges.

A ball check valve is almost maintenance-free, but regular inspection and cleaning can increase its service life and efficiency.

Ball check valves usually require only a small opening pressure and remain open during flow without springs or other mechanical components.

The service life of a ball check valve depends on the operating conditions and material, but they are designed to last a long time when properly maintained.

If a ball check valve breaks, it should be repaired or replaced as quickly as possible. Spare parts and repair services are available from manufacturers or authorized dealers. BPI-Chempump can replace a broken valve or supply spare parts.
