3 Way Ball Valve L Port
To achieve control of the fluid through the three-way ball valve, you must consider a combination of how your pipeline is set up and the handle rotation pattern and the flow path configuration of the ball bore.

3-Way-Ball-Valve-L-Port-Flow-Pattern

3 Way Ball Valve T Port Flow Pattern

Using the right 3 way ball valve type and configuration, you can achieve the following flow path control:

◎ Completely close the flow paths
◎ Mixing the fluids from two different pipelines
◎ Diverting fluid from one direction to another one
◎ Splitting the flow from one source to the other two different pipelines
◎ Alternately closing one flow path and opening the other

In a typical Kinvalve three way ball valve, the internal pattern of the ball port determines its working mode and type.

The 3 way ball valves with different opening modes can achieve different functions. At Kinvalve, 3 way ball valves have balls with the flow path patterns like either L or T.

Kinvalve 3 way ball valve L port is the commonest 3 way ball valve. This L ball valve is used to transfer flow from one inlet into one of the two different outlets. This is why 3 way ball valve L port is often called the diverter ball valve.

At Kinvalve, diverting ball valves or directional ball valves are alternate names used for 3 way ball valve L port. Because this L ball valve is widely used to divert or transfer the flow path from the inlet into one of the two different outlets.

The handle can only rotate 90 degrees L port ball valve, also called a two-position 3 way ball valve.

This 3 way ball valve L port can be rotated either to the left or to the right to transfer the flow path from one of the two outlets to the other.

At Kinvalve, there is the other kind of L port ball valve, its handle can rotate 180 degrees. In this way, the handle can be parked in three positions.

This 3 way ball valve L port can completely shut off the flow path. This 3 way ball valve is usually called a three-position 3 way ball valve.

In the case of most horizontal type 3 way ball valves L port, the stems are limited to 180 degrees. This provides for three options for your application:

  • Transfer to left flow while closing the right flow path
  • Transfer to right flow while closing the left flow path
  • Completely shut the outlets

3 Way Ball Valve T Port
Kinvalve 3 way ball valves T port are widely used in mixing applications. In these systems, the tee ball valves take two inlets, and the third port is used as an outlet to flow out the mixing fluid.

3-Way-Ball-Valve-T-Port-Flow-Pattern

3 Way Ball Valve T Port Flow Pattern

Of course, depending on the process requirements, you also can take one port as the inlet to split the fluid into the other two outlets. These two processes are opposite.

Our tee ball valve is used to divide flow and be used the same as the L port ball valve to divert flow from one outlet to the other.

The same as the L pattern, Kinvalve 3 way ball valve T port changes the flow paths with a 90 degrees rotation of the stem.

They can provide diverting, mixing or splitting, and straight-through flow by the allowed range of stem motion.

A big difference between the L port ball valve and the T ball valve is that a typical T ball valve can’t use for your full shut-off application.

Mixing ball valve is an alternative name for T ball valve. Because this T port ball valve is widely used to mix or combine flow coming from two different pipelines in your system.

And the same as the L port ball valve, the turns of the stem can be limited by using a handle stop design.

Kinvalve also can design the three way ball valve with a latch locking device, it allows the handle locked in either position.

On some specific occasions, you may need this lockable device to prevent operation by mistake or some unauthorized people control by purpose.

3 Way Ball Valves: The Ultimate FAQ Guide

In this guide, you will find all information you’re looking for about 3 way ball valve.

Whether you want to learn about the features, benefits, working principle or designs – you will find all information right here.

Keep reading to learn more.

What is a 3 Way Ball Valve?

A 3 way ball valve is a multi-port ball valve with 3 openings, usually known as ports. Tubing and piping are connected to these ports to enable fluid or gas flow control.

Depending on the direction of flow through the 3 way ball valve, these 3 openings are often described as:

  • Single outlet and two inlets
  • Single inlet and two outlets

3 way ball valves will provide you with a simple way of controlling both flow direction and shut off in a single body.

3 Way Ball Valve

 3 Way Ball Valve

What are the Components of 3 Way Ball Valves?

The 3 way ball valve construction has the following crucial parts:

  • Body: This is the main component of the 3 way ball valve. It houses all other components for off and on control.
  • Stem: This component provides a connection between an external control mechanism, e.g., lever or handle, and the ball component.
  • Rotary ball: Being a ball valve, the 3 way ball valve uses a ball with a centre bore to allow media flow. These bores are cut out channels. You can control this component by turning the stem.
  • Seats: These components provide a seal between the ball and the body as they are located between said components.
  • Actuation handles or levers: As an operator, you will use these components to turn the ball.

This component has markings that serve as indicators for direction of flow of fluid through the 3 way ball valves.

  • Bonnet: This component houses the packing and stem components.
  • Packing: Prevents media escape as it acts as a seal around the stem component.

How does a 3 Way Ball Valve Work?

Turning the lever/handle turns the ball component of the ball valve to align its cut out channels to the valve outlets and inlets.

Different levels of control are achieved depending on the degree of handle rotation or ball port type. The common types of ports are T port and L port.

L port 3 way ball valves have an L shaped cut out channel.

This implies that media will be sent from one port to another through a 90 degree angle when actuated.

T port 3 way ball valves have a T shaped cut out channel that can send media from one port to another. These ports can also be aligned to the 3 way ball valve’s T shape to mix all the ports.

What are the Applications of 3 Way Ball Valves?

Typical applications of 3 way ball valves are water chiller, air handling and fan coil units.

You can use 3 way ball valves to open flow in one pipe while shutting off flow in another line.

You can also use 3 way ball valves to mix media from two separate inlets into one pipe or one inlet into two outlets.

Applications may vary depending on the port type. T port 3 way ball valve applications include:

  • Combining flow coming from two separate inlets.
  • Splitting the flow of media between two outlets.
  • Allow mixing of media from two separate inlets.
  • Alternating the flow of media between separate outlets.

L port 3 way ball valves include:

  • Diversion of flow to allow seasonal demand accommodation.
  • Changing source of media flow.
  • Diversion of flow from one destination to another.

What are the Available Types of 3 Way Ball Valves?

The different types of three way ball valve include:

Diverter Valve

The alternate name for this type of 3 way ball valve is the L port ball valve. This is because its design enables you to change or divert the flow going out through one port or outlet.

These 3-way ball valves have a single inlet and two separate outlets.

T Port 3 Way Ball Valves

 T Port 3 Way Ball Valve

T Port 3 Way Ball Valve

These are commonly referred to as 180° ball valves and you can use them to accommodate two inlet flows.

These combined flows can be mixed together to flow out through a single outlet. The reverse is possible depending upon the specifications of your project.

You should consider this type if your process requires mixing, straight/split flow, or diversion through the valve.

It’s also worth noting that this type of 3 way ball valves will not provide shutoff control. You can only use them to prevent flow from any two ports.

What Factors should you Consider when Choosing a 3 Way Ball Valve?

Some of the key considerations during selection of 3 way ball valve include:

Operating Pressure

You should check the 3 way ball valves pressure ratings before purchase. These ratings should correspond to the pressure requirements for your intended application.

Some 3 way ball valves are not designed to accommodate immense pressure.

Not doing so will could potentially cause problems like seepage, which may slow down your process in the long run.

Figure out the exact size of the valve you need to accommodate said pressure.

Ball Valve Capability

Some 3 way ball valves are not capable of handling extreme temperatures. This is mainly attributed to the materials they are made from.

Before purchasing a 3 way ball valve, you should determine what temperature the media has to be at to pass through.

Different materials have different extreme cold and hot conditions resistance levels.

Choose a 3 way ball valve that is made from a material that is adaptable to your processes’ temperature requirements.

Type of fluid you will be Passing

While the 3 way ball valves are versatile, they are not suitable for controlling all types of media.

Some materials may contain suspended solids and debris that may cause damage to the 3 way ball valve. Thus, slow down your process in the long run.

Volume of Fluid you will be Passing Through the Valve

You must identify the amount of fluid volume that you intend to pass through the 3 way ball valve.

Selecting valves built from robust materials, like stainless steel alloys, to handle the fluid volume is the best choice.

It will ensure your safety and that of people handling your pipeline system.

Cost of the 3 Way Ball Valve

The cost of the 3 way ball valve is also an important consideration to make. You must select one that is in your budget and still deliver top notch performance.

You should also take auxiliary costs like installation costs into account when choosing a 3 way ball valve.

In that regard, it is good to check our catalogue to find a 3 way ball valve within your budget.

Generally, you require 3 way ball valves in specific applications where firm closure is essential.

Check out the factors mentioned above to get yourself the best possible product for long time and robust usage.

How do you Tell the Direction of a 3 Way Ball Valve?

A T shaped or L shaped arrow symbol is on the 3 way ball valve handle. This symbol mimics the ball component’s cut out part.

You can determine the direction of media flow by referring to this symbol.

Simply put, the handle has an arrow symbol that indicates the position of the port inside the 3 way ball valve.

How do you Install a 3 Way Ball Valve?

For T port 3 way ball valves, you should ensure that the inlet, i.e., port A, is piped to the coil to maintain proper control.

Ensure that the other inlet, i.e., port B, is installed in a way that yields 70% of the flow from port A.

For L port 3 way ball valves, you should pipe port B as the central bypass port perpendicular to the flow.

The 3 way ball valves come in a variety of end connections. These connections range from ANSI flanges, ¼’’ to 2’’ NPT connections, to glue sockets.

The advantage that comes with such connections is that they give you the ability to remove the valve body for replacement or servicing.

Without this ability, you would have to cut the pipe on two valve sides. This will slow down your process.

What Materials are 3 Way Ball Valves Made from?

Different parts of the 3 way ball valves are made from different types of materials.

The ball, body, and stem are usually made of materials like PVC, Carbon Steel, Brass or Stainless Steel.

Using such allows the valve to accommodate up to 232 PSIG pressures at 73°F and work in temperatures of up to 140°F.

The manual hand lever is made from PVC material. Similarly, the seat and seal components are made from PTFE or TFM material.

These materials are water-resistant, hence perfect for the application.

Stainless Steel 3 Way Ball Valve

Stainless Steel 3 Way Ball Valve

What is the Pressure Rating of the 3 Way Ball Valve?

A 3 way ball valve can accommodate pressures of up to 100 MPa; 15,000 psi.

These ratings are primarily affected by the type of materials used and the overall design of the 3 way ball valve.

What are the Advantages of 3 Way Ball Valves?

The main advantages of a 3 way Ball Valve are:

  • Provides a simple structure, compact design, low volume, and less weight.
  • Offers low resistance to the media passing through the valve.
  • The sealing of the 3 way ball valves is excellent. Thus, you can employ them in vacuum systems.
  • Maintenance of the 3 way ball valves is simple and will save you time.
  • 3 way ball valve elastomers are changeable. This helps when you need to adapt your valve to processes that may require accommodation of different flows, conditions and temperatures.
  • Come in various sizes, increasing the range of applications you can use.

Why are Handles an Important Part of 3 Way Ball Valves?

The handles of the 3 way ball valves turn within a given range of motion. You can control the 3 way ball valve by turning the handle to shut off or to open flow.

Moreover, handles have a visible arrow symbol on them that mimics the cut out channels on the ball component.

This could come in handy when trying to determine the direction of media flow through the 3 way ball valve.

What are the Major Disadvantages of 3 Way Ball Valves?

  • Have terrible throttling properties. Due to high velocity flows, the partially exposed seat in a throttling position can make it vulnerable to erosion.

As a result, we do not recommend 3 way ball valves for such applications.

  • Wear and Tear

Ball valves may stick in place and become stuck if used to control the wrong type of media. Slurries have suspended particles that may get trapped and cause this problem.

The 3 way ball valve may wear out, get stuck or become damaged in the long term.

 What are the Flow Patterns Supported by 3 Way Ball Valves?

Flow Direction of 3 Way Ball Valve

 Flow Direction of 3 Way Ball Valve

L Pattern Flow

The L pattern 3 way ball valve makes a shift in the flow from one port to the other. You can do this by rotating the handle or actuator to 90 degrees.

Suppose the first position is opened by the bottom port and the left port.

A quarter turn in the counter clockwise direction causes the valve to divert the flow of the media to the right outlet.

Another quarter turn in the other direction, allowing a complete rotation of 180 degrees, blocks the passage of media.

A 270 turn will also obstruct the media movement.

However, having a complete 360 turn enables the valve to return to its original place.

Two of the 3 ports are available at one time. This makes it possible for the valve to have two shutoff positions and 3 flow pattern choices.

T Pattern Flow

The T pattern is called a mixer valve since the media of two inlet flows can be mixed within the valve.

It’s leaving the valve on the other end and in a way, you can open all 3 ports at one time.

The T pattern of flow can be similar to that of the L pattern of flow.

You can achieve this with a quarter turn of the handle.

T patterns cannot have a bubble tight shutoff. However, they can restrict the flow to two ports or facilitate the passage to all 3 ports.

What is a Diverter Valve?

Diverter valve is an alternate name for L port 3 way ball valves. This is mainly because these valves are used to change or divert flow going out through two separate ports or outlets.

What are the Temperature Ratings for 3 Way Ball Valves?

3 way ball valves can accommodate temperatures up to 400 °Celsius (753 °F) depending on the materials used and the design.

What are the Key Features of 3 Way Ball Valves?

The main features of 3 way ball valve are:

  • 3 way ball valves open and close without friction. The design of the 3 way ball valve eliminates the rubbing of components during application.
  • Due to their jacket structure, you can check and maintain the 3 way ball valves directly and cost effectively.
  • The 3 way ball valve’s seat is strong enough to withstand abnormalities in pressure rates.
  • 3 way ball valves have a wedge sealing structure: The valve’s sealing stays robust regardless of differential pressure variation.

The sealing is guaranteed to protect the valve against common problems like seepage.

  • 3 way ball valves are self-cleaning valves. All accumulated burrs and debris are washed off when the valve lifts from its seat keeping the surface clean.

What is the Difference Between 3 Way Ball Valves and 2 Way Ball Valves?

Two way ball valves are commonly used as shut off valves. Their reliability and simplicity make them well suited for such applications.

Additionally, two way ball valves have only two openings or ports. These are the points at which they are connected to piping or tubing systems.

Moreover, the ball component has a single straight hole where the gas or liquid passes through. 3 way ball valves are, on the other hand, more complex.

They have 3 connection or ports.

They can solve more complex flow control requirements than 2 way ball valves.

Thus, making them more versatile and applicable in a wider range of processes.

A difference also arises in the prices of both valves. 2 way ball valves are less costly compared to 3 way ball valves.

Using 3 way ball valves guarantees saving money in the long run with regards to maintenance costs and replacement of parts.

What is the Difference Between a 3 Way Ball Valve and a 3 Piece Ball Valve?

Comparison between 3 way ball valves and 3 piece ball valves can be drawn from their design and structure differences.

In this regard, 3 piece ball valves have two ends or ports while 3 way port valves have 3 ends.

Moreover, the cut out channel in the 3 piece ball valve ball component is straight.

The cut out channel in the 3 way ball valve ball can be L-shaped or T-shaped depending upon the type.

How Long do 3 Way Ball Valves Last?

When used under the appropriate conditions, 3 way ball valves can last very long.

However, they will lose their functionality over time and wear out.

They will not last forever, but we guarantee that they will last for at least 3 years.

How do you Maintain 3 Way Ball Valves?

  • To enhance the operability and service life of your 3 way ball valve, you should conduct frequent inspections.
  • Please keep a record as you inspect them at least once every six months. Be on the lookout for malfunctions that may cause leakages and fix them as soon as possible.
  • You should periodically inject grease through the fittings of your 3 way ball valves. You should do this about once every six months.

Like the stem journals, other components do not require routine maintenance as they are already lubricated permanently at the factory.

  • After injecting grease, you should ensure that the ball’s diameter is aligned to the seat’s inner cavity plane. If it’s not, you should adjust the actuator’s stop ball.
  • Before disassembling, you should isolate the 3 way ball valve from flow and pressure.

This is a maintenance procedure that will go a long way in ensuring the safety of both you and the valve.

What Test and Design Quality Standards Do 3 Way Ball Valves Conform To?

  • JB2311 78 and GB12220 are Chinese valve standards for ball valve technology requirements and valve marking, respectively.

The markings indicate useful information like pressure ratings.

  • ANSI/ASTME PTC25.3 standards for valve characteristic testing solutions.

This means that the valve has been put through tests to determine whether or not it can handle certain working conditions.

What are the Signs that the 3 Way Ball Valves are Failing?

  • 3 way ball valve handles not moving. This is a common sign of failure. It occurs when debris enters the valve and damages the seal.
  • A damaged seal will seal entirely and may result in fluid or gas seepage.
  • The 3 way ball valves will often be noisy.
  • The 3 way ball valve may start vibrating.

What Determines the Cost of 3 Way Ball Valves?

The main parameters that dictate the 3 way ball valve price are:

Materials

Different materials with varying characteristics are used to manufacture 3 way ball valves. Some wear out faster than others and are thereby cheaper.

This simple factor determines the 3 way ball valve’s versatility, longevity, durability, and strength. All of which are parameters that bring variations in the prices of 3 way ball valves.

3 Way Ball Valve Type

Different types of 3 way ball valves perform different functions, e.g., L port valves are diverter valves.

Hence they will be priced differently from T port valves which are mixed valves.

When choosing your 3 way ball valve, you should consider how much space is available for the valve accommodation.

3 way ball valves are space saving valves in general and will provide you with quality fluid flow control.

Once you understand everything in this guide, it is easier to choose high performance 3 way ball valves.
