Managing fluid flow in different industrial applications requires the use of multiple valves which start, stop or redirect the flow of fluids. Most of these valves are two-way, meaning they have an inlet and outlet port. As explained by the industry leading valve manufacturers, some flow applications require a third port, providing two inlet ports and a single outlet or two outlets and one inlet port. This implies that these valves can perform the same functions as two-way valves and exhibit better performance characteristics.

Three-way ball valves particularly Three-way ball valves offer a cost-effective means to control fluid flow in different applications by minimizing or eliminating multiple two-way valves for certain operations.

Three-way ball valves are popular in industrial boilers, chemical mixing pipelines, steam collection and distribution systems, air conditioning devices and complex piping systems containing primary and secondary loops. These valves are available in two internal configurations, which affect their performance in the mentioned applications, as explained by leading ball valves supplier.


The three-way ball valves are mainly of two types namely T shaped three-way ball valve and the L shape three-way ball valve, wherein both these valves when compared to the normal ball valve differ in the functionality and performance.

T Shaped: Mixer valve is another name for T pattern valve. You might think why this valve is known as a mixer valve. It is because the substance of two inlet streams can be combined, shared, or diversified within the valve. On the other end, it drops the valve. In this manner, all three ports can be unconfined and have the ability to achieve any type of function at a time.

The T-shaped ball valve also works as the L-type valve or diverter in a similar way. It could be accomplished with a handle of the fourth turn. To enable the passageway to all three interfaces a T-shaped valve is used in the working to control the flow.

L Shaped: The diverter valve is another name for an L-shaped style valve. It simply marks a change in the movement of flow from one port to another port just by rotating the handle to 90 degrees. The foremost plug is unlocked by the close port and the left port. In the counter clockwise track the fourth shot sources the valve to bounce the flow of liquid and gas to the apt opening way.

On the other hand, one more fourth turn in a different route permits a perfect rotation of 180 degrees. It blocks the channel of all sorts of media. A turn of 270 degrees will also complicate the flow of liquid or gas.

Guidelines to be follow:

As an industrial valve, a three-way ball valve is highly used for converting valves, by-pass valves, opening valves, closing valves, directional valves, and more with the help of an L-shaped ball-type valve. And, T-shaped ball-type valve is suggested and highly used for merging valves, examining valves, suppression valves, and more.

Choose the appropriate valve sizes. Under sizing the three-way ball valve will increase the pumping costs of the system. Oversizing the valve reduces pumping costs but will cause control inaccuracies.

Evaluate the physical and chemical qualities of the service fluids. If using the valve for mixing, the valve material and sealing components must be compatible with the service media. Valve materials, as pointed out by the European valve manufacturers, must adhere to statutory regulations and certification standards which acts as a industrial benchmarks. The pressure and temperature ratings of the three-way ball valves should accommodate the flow conditions and variations of the service fluid.

Confirm the connection types of the three-way ball valves to ensure they are compatible with the existing pipelines. As advised by most valve suppliers when choosing the valves, select a connection method that will simplify the maintenance of the piping system, valves and actuators. Three-way ball valves having flanged connections are easier to maintain and replace than their welded counterparts. Also, consider the actuation mechanisms as well as the fact that what type of actuators will meet the requirements of the piping system?


The multiport configurations of the three-way ball valves allow better flexibility and control in different industrial applications. The valves have different internal designs that give them unique performance characteristics. The capability of a single three-way ball valve to handle the diverse flow applications implies that fewer valves are required. It reduces the cost of installation, operations and maintenance.
