A spring-loaded or free-floating ball on the sealing seat of a ball check valve closes the valve opening. The chamber is conical in shape, and the seat is machined to fit the ball to seal and stop a reverse flow. If the pump’s capacity is insufficient, A lighter ball can be used, while a heavier ball can prevent water hammer when the pump stops. Since they only need to be maintained if the ball produces noise due to inadequate pump capacity or water hammer, ball check valves are frequently chosen for use in pumping stations that are rarely crewed. In the plumbing business, ball check valves are frequently employed. Read More…

Our ball valves include high pressure valves, brass ball valves, stainless steel valves, 3 way valves and ball check valves. In business since 1925.
These valves stop water from running backward through piping systems, sump pumps, and water heaters. Among other materials, PVC, brass, or stainless steel can be used to make ball check valves. The ball inside the valve is normally manufactured from metal. Ball valves typically have specific, low-cost metallic components, while specialty ball check valves are also available. For instance, the ball is made usable in high-pressure pumps in the analytical chemistry industry by using synthetic ruby, a robust and chemically resistant substance.
Working Principle of Ball Check Valves
The basis of the ball check valve's operation is its ability to let flow in one direction while automatically blocking it in the other direction. The control mechanism or disk must open to let the flow from the intake to the outlet due to the liquid pressure.
The disk will automatically seal the channel and stop the reverse flow if the inlet pressure is lower than the outlet pressure. A ball that is either free-floating or spring-loaded and rests on a sealing seat near the intake functions as the control mechanism in ball check valves. The ball rises from its seat and permits the flow when the fluid pressure exceeds the cracking pressure.
How to Install a Ball Check Valve
There are two ways to install check valves technically:
- Ahead of the pump
- Back of the pump
A bottom valve is a device put in front of the water pump and at the vertical suction pipe's end. For this installation to function optimally, The pump should be installed higher than any liquid or water level. The negative pressure technique is another name for it. The valve is placed in front of the pump to fill it with water rather than letting it run dry.
When the liquid level is higher than the pump, the second way of attaching the check valve behind the pump is the best option, and This makes it possible to quickly close and open the water pump without having to close the pump output valve. A ball check valve can be mounted horizontally and vertically in a plumbing system.
- Examine the valve's interior and take out any strange objects you find there.
- Push the ball away from the seating surface to make sure it can move freely.
- Check the valve ends for any raised burrs or edges that could prevent the valve from sealing during operation.
- The flow direction must be up-arrow if the installation is vertical.
- The valve cover must be positioned with the top facing up if it is placed horizontally.
Applications of Ball Check Valves
- They are used in systems for sprinklers and pipes.
- Backflow and the re-entry of possibly polluted water are both prevented using ball check valves.
- Devices like liquid pump dispensers, sprayers, and dispensing syringes all use ball check valves.
- They are used to force plastic forward during the injection molding process and prevent any from sliding backward.
Advantages of Ball Check Valves
Very efficient
Because of the size of the ball's aperture, which contributes to its low-pressure drop and high flow capacity, ball check valves are classified as high recovery valves.
Convenient usage
Ball check valves are effective and convenient due to their straightforward quarter-turn (90-degree) function. In addition, this valve is simple to install and remove because it is lightweight and compact.
Minimal maintenance
Compared to other valve designs, ball check valves are simple to use and require minimal maintenance. In addition, the packing seal on the valve stem does not easily wear out or fail since the ball check valve stem rotates without axial movement.
Cost-efficient
Compared to more complex valve types, ball check valves are less expensive. Additionally, they require less maintenance and are less expensive to maintain.
Durable
Because they can tolerate high pressures, ball check valves are among the most durable valve types.
Disadvantages Of Ball Check Valves
Prone to blockages
Slurries and other viscous liquids tend to harden or clog up inside valve cavities, significantly increasing working torque and, in some situations, making the valve inoperable.
Suffer from long-term throttling
Ball check valves shouldn't be used for long-term throttling and should only be left in fully open or closed positions.
Choosing the Correct Ball Check Valves Supplier
To make sure you have the most beneficial outcome when purchasing Ball Check Valves from a Ball Check Valves Supplier, it is important to compare at least 4 or 5 Companies using our Ball Check Valves directory. Each Ball Check Valves Company has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each Ball Check Valves company website using our proprietary website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple Ball Check Valves companies with the same form.
