Defined by its number of ports, the 3-way valve is a type commonly used in industrial applications. Due to its inevitability in the industrial world, it is therefore important to take a look into what this device mean, the types, how it works, and other salient factors.

A 3-way valve is an industrial valve with a steady flow rate used for diversion or mixture of applications. It&#;s also known as a multiport valve because of its three openings which can be connected to tubing for the flow of liquid or gas. These openings in the 3-way valve types either come as two inlets and one outlet, or one inlet and two outlets. This is determined by the connection application.
The rate of flow in the different valves remains steady despite being a multiport valve. A constant flow rate is maintained in any application where the valve is used even though the liquid or gas will be split into two separate openings.
The structure of this valve allows one open orifice with the other one closed or vice versa. This makes it easy for the device to be used for pressure application as an option to exhaust pressure from a valve actuator or a single-acting cylinder. 3-way valves are normally opened, closed, or universal.
This mechanism devised by the valve allows it to provide a convenient way of moving the flow of liquid or gas from one point to another.
Furthermore, the mechanism of the 3-way valve also makes it inexpensive, allowing its users to save money by eliminating the use of conventional gate valves and bypass appliances often used in steam generating plants. Not only does it eliminate conventional 3-way globe valves, it also shut-off control in one single valve body and provides flow direction.
A 3 way ball valve symbol is a modification of the 2 way ball valve symbol, which consists of two triangles facing each other with a ball at the center.
In the 3-way ball valve symbol, three triangles are pointing towards each other with a ball at the center. This goes to show that this valve can be generic when it doesn&#;t indicate the type of 3-way ball valve present or it can be a symbol with a modifier when it shows the exact type of 3-way ball valve present in the piping.
The symbol is of two types: generic symbol, and the symbol with a modifier.
The 3-way ball valve, like other ball valves in the multiport valve family, has its types. It is therefore important to know them.
There are two major types of three-way valves: The T-port valve and the L-port valve. They are named after their shape, and their usages are dependent on the function you want them to perform. The T and L shapes refer to the opening in the middle of the 3-way ball valves.
The T-port valve is thus named because it has a T shape. It is also called the 180-degree ball. This ball valve type can merge two inlet flows into one outlet port. Depending on the system requirements, it can also split one inlet into two outlet flows.
The T-port 3 way valves are commonly used to split the flow of gas and liquids. Based on the permissible range of the handle motion and the system&#;s requirements, the T-port 3 way ball valve can be used in splitting or mixing flow, diverting flow, and enabling a straight flow.
In addition, the T-port valve can not only flexibly control the merging or diverging of the medium in the pipeline, but also make the three channels communicate with each other.
The 3-way ball valve T port can be used to connect the openings in a pipeline, allowing for different inlet and outlet flow patterns. Generally, the 3-way ball valve T-port valve is preferred in most cases as it allows for multidimensional flow patterns, unlike the L-port valve which seems to be non-dimensional.
The T-port valve ensures a straight flow through the valve when it is in one position with little or no loss of pressure and diverts to another direction when the position is changed.
The 3-way ball valve T-port valve can have up to two paint sprayers simultaneously alongside the three ports connected.
The L-port 3 way valve is also called the 90 degrees ball. This ball valve allows the flow of liquid or gas from one inlet into one of the two separate outlets. Its mechanism in the L port 3 way ball valve gave it the name &#;diverter valve&#;. Unlike the T-port valve, the L-port 3 way ball valve diverts or coordinates flow in one direction.
It can restart, restrict or shut off the flow, unlike the T-port valve. The handle of the valve has its ranges in 90 degrees i.e it&#;s calibrated in 90 degrees, 180 degrees and so on until it gets to 360 degrees. However, whatever angle it takes, the direction is in one way.
The L-port ball valve is quite useful in applications where more than one source is used in drawing liquid or gasses into another pipe.
There&#;s the double L-port ball valve which is a 4-way valve used to confirm flow with 4 pipes connected to a valve. There are also flanged valves which have their ends flanged in order to connect to any pipe either with a bolt or by welding.
The L-port way valve is used in applications that need a diverter. This is because it can divert flow from one primary source to another. This valve also allows simple switching between pumps, i.e, switching liquid or gas from one pump to another.
In addition, the L-port 3-way valve allows diverting flow from and between storage tanks as well as from cooling to chilling.
The 3-way T-port valve and the L-port valve are the main categories of the 3-way ball valve, which also entails the following:
Several industrial valve manufacturers believe that the 3-way valve is one of the most used valves as it gives room for different system requirements, allowing different styles of flow in a pipeline or in whatever system it is applied.
It is important to note that the design of the valve determines the style and flow pattern in a system. The advantages of the 3-way ball valve cannot be overemphasized as it does not just fit into any system but can perform more than one function.
Below are some of the various advantages of the 3-way ball valve.
As stated earlier, 3-way valve function is largely dependent on the system requirements. Since it can be used for a wide range of applications, the functions will be dependent on what is required of the valve in the system where it is applied. Some of such functions include:
These and more are determined by the system requirements, thus the design of different types of 3-way ball valves.
Just like multi-port ball valves, the 3-way ball valve provides a control for piping applications. Its mechanism differs a little bit according to the type and this is because it works by turning a handle or by turning on an actuator (this is for 3-way electric ball valves).
This action rotates the ball inside the multiport valve causing the channels to align with the inlet and outlet ports giving direction to the flow of liquid or gas. The handles have a range of motion and the range of motion differs according to the type.
Quickly, let&#;s explore the mechanism in the L-port 3-way valve and the T-port 3-way valve.
The mechanism in the L-port 3-way valve allows the direction of flow of media to be changed by turning a handle to 90 degrees. This means that every time the handle is turned 90 degrees, the direction changes because one port is sealed and then another port opens up. The valve&#;s mechanism doesn&#;t allow the three ports to be open at the same time.
The mechanism in the T-port valve or the 180 degrees valve allows the three ports to be open simultaneously. The T-port valve allows media from two different ports to be mixed in the body of the valve and exit through the other opening. The T-port shape allows media to flow in through two ports and out through one and vice versa.

The bottom line is the mechanism of the 3-way ball valve is not fixed, but can change according to the type of valve used and the system requirements.
Generally, valves or ball valves play very important roles in industrial processes. The 3-way ball valve is not the only existing ball valve. There are several valves existent, but the 3-way ball valve because of its flexibility seems the most common.
The question is, what is the difference between the 2 way ball valve and the 3 way ball valve? Is it just the name that&#;s different or are there characteristics that make them different?
The differences between the 2-way ball valve and the 3-way ball valve are majorly hinged on the number of ports they possess. These ports determine the mechanism of the functions they perform when attached to piping or tubing for liquid or gas.
Given how flexible a 3-way valve is, one would think that handles are of less use for the valve. The handles though are significantly more important than we can imagine. The 3 way ball valve is powered by a handle. The handle is more or less the deciding factor of how efficient the 3 way valve works.
Generally, all ball valves come with handles which keep them from exceeding a certain degree of turn. For the this ball valve, handles are important because of the number of ports of the valve. The handle provides control through its limited range of motion.
The range of motion specifies the amount of liquid or gas that is to be mixed or diverted. In essence, the flow pattern in a three-way is determined by the handle.
Practically without the handles on a 3-way ball valve, there will be no control of the amount of media that will pass through the valve. It eventually will end up in a mess as an excessive amount of media can go through the valve and can eventually cause a breakdown in the piping system.
3-way ball valves are one of the most important types of ball valves; they serve diverse roles in different systems in industrial processes. They play significant roles at different points in a pipe and tube system for liquid or gas flow.
Proven to be cost-effective, its mechanism is a good show of flexibility as it fits into a wide range of system requirements allowing the valve to perform different functions in different systems at a time. For industrial processes and their complexities, the 3-way ball valve will be the best pick because of all its capabilities. Contact a professional valve factory to know more about it.
A 3-way valve has three ports. The 3-way ball valve is one of the main 3-way valves, which can be used to maintain fluid or gas flow through a piping system. The valve has a primary flow path, which connects two ports, and a secondary flow path, which connects the main flow path to the third port. The fluid or gas flow can be redirected as needed by opening and closing the valve in various ways.
Brass 3-way ball valveThe 3-way valve is vital in many fluid and gas handling systems because it allows for precise flow, direction, and pressure control. Some of the key benefits and uses of 3-way valves include:
A 3-way valve can divert the flow of a fluid or gas between two different output ports or mix two various liquids or gases into a single output port.
The flow capacity of a gas or fluid can be regulated by controlling the opening and closing of the various flow paths in a 3-way valve.
A single 3-way valve can often replace two separate valves, reducing the installation cost and space requirements.
3-way valves can be combined with sensors and controllers to create more complex and automated control systems.
In some applications, 3-way valves can be designed to fail in a safe position, reducing the risk of damage or injury.
A 3-way valve provides three different pathways for fluid or gas to flow through, each of which can be controlled to either block or allow flow. The valve typically consists of a central body with three ports: one inlet and two outlet ports. The main flow path connects the inlet port to one of the outlet ports, while the secondary flow path connects the main flow path to the other outlet port.
When the valve is in the sealed position, both the primary and secondary flow paths are blocked, and no fluid or gas can flow through the valve. When the valve is in open condition, one of the outlet ports is connected to the inlet port via the main flow path. In contrast, the other outlet port is connected to the inlet port via the secondary flow path.
Adjusting the valve&#;s position allows the fluid or gas flow to be redirected between the two outlet ports or shut off entirely. Sometimes, a 3-way valve may mix two streams of fluid or gas by partially opening both outlet ports and allowing them to combine in the main flow path.
The T-port and L-port valves are known as three-way valves due to their T shape body with 3-parts. Both divert flow to and from the various parts. Yet, the L port valve permits one action, whereas the T port valve facilitates another. Here are the main types of three-way valves:
This type of valve has a T-shaped bore, allowing flow through the valve in three directions. This valve can mix, divert, or bypass fluid flows.
A T-port three-way valve is a type of valve that has a T-shaped bore or flow path. It allows flow through the valve in three directions and can be used for mixing, diverting, or bypassing fluid flows.
The valve has three ports: the inlet port, the outlet port, and the standard port. The common port is connected to the T-shaped bore, where the fluid or gas flow is controlled.
T-port three-way valves can be designed with different actuation mechanisms. When the valve is actuated, a disc or plug inside the valve rotates or moves to redirect the flow path to the desired port.
The T Port Valve is typically used to direct flow in both directions. Fluid is continuously required to multiple locations, passing through the valve body and the side port at a slightly lower pressure.
t portThis type of valve has an L-shaped bore and can be used to divert fluid flow between two ports or mix two different fluid streams.
Most of the time, the L Port valve is used to make the flow from two different sources flow in an identical direction. For instance, when emptying tanks, you can draw fluid from the next tank to the same line by turning the handle to switch the source.
L and T port comparisonProper maintenance of a 3-way valve is vital to ensure its reliable and safe operation. Here are some general maintenance tips for 3-way valves:
Periodic inspection of the valve body, stem, and other components can help identify any signs of wear, damage, or leaks. Any abnormalities should be addressed promptly.
The valve stems, and seat may need lubrication to reduce friction and wear. Use the manufacturer&#;s recommended lubricants and apply them according to the recommended schedule.
Cleaning the valve internals may be necessary to remove any buildup of sediment or debris that may cause clogging or damage to the valve components.
Regular maintenance, including checking the air or hydraulic pressure, can help ensure proper valve operation if the valve has an actuator.
If the valve has position indicators, they should be calibrated periodically to ensure that they are providing accurate readings.
Suppose any valve components are worn or damaged during the inspection. In that case, they should be replaced promptly to prevent further damage or failure of the valve.
