Leading Ball Check Valve Manufacturers

A form of ball valve where the ball is forced to move by pressure from gases or liquids is a ball check valve. The valve automatically closes when the fluid’s pressure on the ball ends. The seat is manufactured to fit the ball, while the chamber is formed conically to help the ball enter the seat to seal and stop a reverse flow. Lighter balls can be chosen if the pump’s capacity is insufficient, while heavier balls can be chosen if the water hammer occurs after the pump stops. Read More…

Ball Check Valves The basics of check valve installation, whose characteristics ball check valves share, involve a disc, ball or cone-like plug to rest on the seat or passageway in the cross section of the valve, blocking the flow of materials.

Design of Ball Check Valves

Two-port valves, such as ball check valves, have two apertures in the body—one for fluid entry and the other for fluid exit. Gravity and reverse liquid pressure are required to reseal every ball-style check valve. Four components make up a standard ball check valve: a body or pipe; a ball; a valve seat; and a specifically-made conical spring. The gases or liquids flowing through the body exert pressure, which causes the ball to rise.

By opposing the force generated by the rising ball, the conical spring balances the volume of the flowing liquid or gas. They are intended to stop water from running backward via the pipe system, sump pumps, and water heaters and are most frequently utilized in the plumbing sector. Brass or stainless steel are two materials that can be used to make ball check valves.

Considerations in Ball Check Valve Selection

Operating Conditions

When choosing the housing materials, it is important to consider the ambient heat generated by the valve during operation. When temperatures are high, brass is a great material for valve housing.

Life Expectancy (Upkeep)

To determine the necessary maintenance, consider the valve's expected average lifespan. Ball check valves of stainless steel have a high level of resistance to abrasion, pressure, and temperature.


PVC ball check valves are a fantastic option if a gas or corrosive liquid is used as the operating medium. However, compared to valves constructed of brass and steel, these have lower pressure ratings.

Reduced Pressure

When choosing a ball check valve, it is critical to understand the pressure drop within the flow management system. The flow is controlled by variations in system pressure, which also affects how well the ball check valve works. When the downstream pressure exceeds the upstream pressure, the reverse pressure drop determines how tightly the valve closes off during backflow. A minimum pressure difference is required between a ball check valve's input and output ports. When selecting a valve, ensure it satisfies this demand and considers the required maximum pressure.

Control Method

A ball check valve allows fluid to flow forward but prevents it from flowing backward. The ball's weight, back pressure, a spring, or a combination of these mechanisms all work together to stop backflow. The ideal ball check valve should have no resistance to flow going forward and complete resistance to flow going backward.

Types of Ball Check Valve Connections

The following list of connection types applies to ball check valves:

  • Flanged Ball Check Valves: Ball check valves with flanges on the inlet and outlet connections are known as flanged ball check valves. The flange is sized and drilled in compliance with specifications like EN 1092-2. Plumbing, firefighting, HVAC, and water/sewage treatment applications all require flanged ball check valves.
  • Threaded Ball Check Valves: Threaded ball check valves contain internal or external threads for inlet or outlet connections.
  • Soldered Ball Check Valves: These valves' ends are attached to the pipe fittings by soldering.
  • Ball Check Valves as Compression Fittings: Ball check valves have a threaded or soldered-free sealed pipe connection.
  • Ball Check Valves with a Buttweld Connection: Ball check valves with a buttweld connection for the inlet or outlet ports are known as buttweld ball check valves.

Uses of Ball Check Valves

  • They’re found in systems for sprinklers and pipes.
  • Backflow and the re-entry of possibly polluted water are both prevented by using ball check valves.
  • Devices like liquid pump dispensers, sprayers, and dispensing syringes all use ball check valves.
  • Ball check valves are used to force plastic forward during the injection molding process and prevent any from sliding backward.

Ball Check Valve Benefits

  • Little size
  • Simple to use
  • Cheap
  • They can be put in places where there is both vertical and horizontal flow.
  • Ball check valves use a variety of media, such as gas, air, steam, vapor, or water, to handle high pressure and enormous fluid volumes.
  • Self-cleaning of the valve is ensured by ball rotation.
  • There are reusable seat rings.
