What is a Ball Valve?
A ball valve refers to a mechanical shut-off device, which controls the flow of liquid or gas through a rotary ball having a bore.
You can also describe it as piping equipment, which shuts-off or regulates flow in the pipeline by using hollow sphere and round seats.
The hollow sphere and round seats are fixed in the valve body.
Ball valve structure
What are the Uses of a Ball Valve?
The ball valve is essential for a variety of uses.
However, the specific use of this device is dependent on the particular application within a specific industry.
The primary use of this device is to regulate, guide, direct, and modulate the flow of different substances like gas, pressure, and liquid.
In this aspect, it makes it possible to determine the volume or rate of flow you need for the particular application.
What are the Types of Ball Valves available?
Ball valves come in different variations in terms of designs and specific uses.
It is advisable to select a type of valve depending on the specific application.
In essence, there is a need for considering different specifications such as temperature, body materials, and connectors among others.
However, the popular types you are likely to come across in the market include the following;
1. Full-port Ball Valve
It is also known as a full bore ball valve.
This type of ball valve is relatively expensive compared to other designs.
The full port ball valve features an oversized ball, which lowers friction loss.
In essence, the hole in this ball is the same size as the pipeline.
Although the valve is a bit large, the flow tends to be unrestricted in full port valve size.
This type of ball valve is often used for throttling applications in numerous systems featuring high flow co-efficient and lower pressure drops.
2. Reduced Port Ball Valve
This ball valve is also referred to as RB or reduced bore.
It has a smaller flow area than the pipe.
The flow through the valve is also one pipe size smaller compared to the valve&#;s pipe size.
RB valve creates a pressure drop in the pipeline.
3. V-Port Valve
The V in this type of ball valve represents either the seat or shape of the ball.
V-ball valve allows you to regulate the opening and closing in a better approach.
The flow characteristic in the V-Port valve is close to linear.
It features a robust construction hence can withstand high velocities of fluids.
4. Standard Port Valve
This ball valve has a relatively small port and ball compared to a full port valve and less expensive.
The flow of this valve is slightly restricted due to the size of the pipe.
It has higher pressure drops compared to other types of ball valves.
Standard port valves are suitable for applications with high flow co-efficient similar to full port valves.
5. Multi-Port Valve
This type of valve has three or four ways with an L to T-shaped hole at the center.
T-valves can connect any pair of ports. Also, the L-valve can connect the center port to side ports.
The inlet in this type of valve is often orthogonal to the outlet plane.
Technically, 4-way ball valves have 2 L-shaped ports in their ball, known as X-port.
6. True Union (Trunnion)
This type of ball valve has a pin to secure the ball in place hence stopping its movements.
It also has two shafts at the opposite ends of the ball. This helps in supporting segmented by the valve.
In essence, this allows the system to cause relatively less friction between various parts of the true union valve.
The trunnion ball valve is suitable for systems with high velocity since they can endure higher pressure.
You can also remove them from the piping system if necessary.
7. Manually Operated Ball Valve
This is the simplest and easiest to use a type of ball valves around.
Here, the closing and opening of the valve happen by a quarter turn.
The only shortcoming of this design is that the quick function may lead to the danger of a water hammer.
What are the Main Components of a Ball Valve?
Ideally, ball valves come in different designs and sizes.
However, most of them tend to share common parts, which include the following;
Parts of ball valve
· Valve Body
It refers to the pressure vessel containing the required components for regulating or shutting-off the flow through a pipe.
The essence of a valve body is to connect two or more sections of the pipe or tubing to each other.
· Seats
These are round donut-shaped discs, which form a seal between the body and the ball.
· Ball
It is a sphere with a hole or tunnel (flow path) through the middle of it and a connection point for a shaft to rotate it.
· Stem
This refers to a shaft connecting the internal ball to the outside of the valve to facilitate ball rotation.
· Actuator
It is an external device designed to rotate the valve stem. This can be a gear, lever, motor-operated gear, or a hydraulic actuator.
· Packing
These are flexible seals, which fit around the shaft and preventing media traveling through the valve from escaping externally.
· Bonnet
It is the part of the valve body, which houses the stem and the packing.
How does a Ball Valve Work?
The working principle of a ball valve entails a variety of aspects.
Importantly, it uses a hollow, perforated, and pivoting ball to regulate the flow of substance through it.
So the ball valve drives the valve handle enabling it to rotate about an axis perpendicular to the flow.
It remains open when the ball&#;s hole is in line with the flow.
Also, it stays closed when it is pivoted at about 90 degrees by the valve handle.
The soft seat tends to flow around the ball&#;s edge orifice and locking the ball in the same position.
This often happens when the ball stays partially open for some time under high-pressure drops conditions across the ball.
The ball moves across the seats with a wiping motion.
While at it, the ball valves handle the fluids with solids in suspension and fibrous material.
On the other hand, relatively abrasive solids tend to damage the seats and ball surface.
Also, long and tough fibrous materials may present a challenge since the fibers tend to wrap around the ball.
Notably, ball valves tend to trap water in the central cavity while in a closed position.
And this can be disadvantageous, especially in a freeze, since the sides can easily crack due to ice forming expansion.
If a ball valve is used for cryogenics, a vent is drilled into the upstream side of the valve, also known as a vented valve.
What Materials are used for Making Ball Valves?
Typically, ball valves work with pressure.
It, therefore, implies the materials used for creating and designing them should be durable.
The essence here is the ability to withstand various environmental parameters like extreme pressure and temperatures.
Some of the popular materials for making ball valves are as follows;
· Stainless Steel
A variety of ball valves are manufactured using stainless steel material.
This material contains numerous positive features such as durability and corrosion resistance among others.
You can use stainless steel ball valves in geochemical systems and general plant systems.
· Iron
This is another ideal ball valve material, which portrays better endurance to various elements such as temperature and pressure.
It is relatively less flexible, but it is one of the materials that makes high quality and durable ball valves.
· PVC
Polyvinyl Chloride (PVC) refers to some elements of thermoplastic material used for designing ball valves.
This material is flexible and smooth.
Therefore, it helps in providing easier movements for ball valve parts.
· CPVC
Chlorinated PVC is similar to ordinary PVC, but it has great tolerance to higher temperatures.
This material is suitable for making ball valves used in handling hot water.
· Brass
This material is ideal for manufacturing ball valves used in systems under low or medium pressure.
Brass has excellent resistance to corrosion and water.
Other materials, which equally offer better results in making ball valves include titanium, flex, Teflon, chrome, and bronze among others.
Is There a Difference Between a Floating Ball Design and Trunnion Ball Valve?
Yes.
Floating ball valve design sandwiches the hollow ball between two or more cupped seats.
In essence, it forms a tight seal between the body and ball at the inlet and outlet ports of the valve body.
The ball in this design is rotated by a shaft protruding outside the valve body.
It is also connected to some type of operator, thus commonly referred to as quarter-turn valves.
The shaft is not attached to the ball rigidly to allow the ball to pivot on the end as the shaft rotates on the axis of the ball.
The working principle of the trunnion design ball valves is similar to that of the floating design ball valve.
However, the seats in trunnion ball valves are spring-loaded against the ball; hence it cannot pivot.
In other words, the ball in trunnion design only rotates on its axis.
Technically, the ball in trunnion design utilizes a second shaft and bearing on the ball&#;s bottom.
The stem, in this case, holds the bottom of the valve in place.
The top of the stem is not slotted, and the upper stem is rigidly attached to the ball.
In principle, it prevents the ball from moving or shifting into the downstream seat.
What are the Types of Ball Valve Housing?
Typically, ball valves are often classified based on the types of housing.
The difference in ball valve housing is based on valve assembly, which is influences the efficacy of maintenance and repair techniques.
However, the assembly of the housing for these devices can be divided into a few common designs such as the following;
Ball valves
· One-Piece Ball Valve
It is also known as a single body ball valve.
This type of housing has a solid, cast body, which is vital in reducing leakage risks.
It is a relatively inexpensive variant of ball valves around.
However, you can hardly open it for cleaning or maintenance.
This type of ball valve is often ideal for low-demanding applications
· Two-Piece Ball Valve
As the name suggests, this is a type of ball valve housing consisting of two pieces.
One of the pieces has one end connection and the body.
The second piece fits into the first one hence holding the trim in place, and includes the second end connection.
You can easily disassemble a two-piece ball valve when you need to clean, inspect, or service.
You must, however, remove the valve completely from the pipe to separate the two parts.
Two-piece ball valves are, nonetheless, slightly reduced bore.
If you are looking for more details, kindly visit Ball Valve Handle Cover Factory.
· Three Piece Ball Valve
This ball valve consists of three pieces; two pieces and a body.
All these three pieces are clamped together by bolt connections.
This housing design allows for easy removal of the center part of the valve from the pipeline.
Moreover, this is essential in facilitating efficient cleaning and maintenance without removing pipes from the valve body.
The advantage of this type of valve housing is that you can easily service it without removing the whole valve from the pipeline.
The three-piece ball valve is relatively expensive compared to one and two pieces.
· Top Entry Ball Valve
This is the type of valve with its balls assembled from the top section.
It thus allows easy access to the seats and balls for effective maintenance without removing the valve.
Most of these types are often made from casting metal hence guaranteeing durability.
The design construction of this type of ball valve allows minimal thread connection.
Therefore, it also reduces the possible leak path.
· Side Entry Ball Valve
This refers to the type that assembled its ball from the side part.
The assembly of this valve is in two or three pieces body.
Also, the assembly of each body component is done by bolt or stud similar to joining two pieces of flanges.
Typically, the side entry ball valve is designed from forge metal.
In essence, every piece of the body is forged and assembled.
The construction of this valve minimizes defects arising from casting valves.
It is easy to assemble the side entry ball valve in addition to aligning the trim component.
· Welded Body Ball Valve
This is a type of assembled in completely welded construction to prevent leakage through-bolt connection.
Welded body ball valves are suitable for underground or buried applications where there are minimal maintenance needs.
How does Ball Valve compare with Gate Valve?
These two types of valves are commonly used flow control devices in the market.
Both are used in more or less similar settings.
However, there are a few notable differences in the following aspects.
· Operation;
A ball valve uses a rotary ball with a bore and a stem.
When you turn the handle attached to the stem, it rotates the ball to either opens or closes the valve.
A ball valve is also referred to as a quarter-turn valve since its handle only requires a 90 degrees turn to control or block flow.
The ball valve&#;s handle also opens when the handle is parallel to the pipe and closed when the handle is perpendicular to the pipe.
On the other hand, a gate valve uses a gate to regulate the flow of media.
The gate is typically a solid-disk structure connected to the stem.
In terms of operation, the gate is lifted to open the valve and returned down to the original position to close the valve.
The gate valve is accompanied by a bonnet, which controls the gate position when rotated.
This valve is also known as a multi-turn valve.
Of course, this is because it takes more than 360 degrees to turn to open or close the valve fully.
Gate valve structure
· Visual Detection;
In the ball valve, it is easy to detect the open and closed state of the valve with the handle&#;s position.
However, this is difficult to achieve in the gate valve since the gate turns multiple times.
· Cost;
The ball valve is ordinarily relatively expensive compared to the gate valve of the same specifications.
· Installation Space;
The ball valve needs more space compared to the gate valve.
The space for the ball valve should be enough to accommodate the quarter-turn handle.
· Leakage
Ball valve provides a tight seal even when used after a long period.
Gate valve, on the other hand, is comparatively more prone to leakages.
Ball valve structure
What are the Advantages of Ball Valves?

Some of the main benefits of making investing in ball valves worthwhile include the following;
- It is relatively durable. This valve is designed from robust materials hence making it possible to be less prone to damages.
Moreover, this enhances the efficiency and performance of this unit.
- It is constructed with a tight seal. In essence, this is fundamental since it prevents the possibility of leakage.
- Ball valve is comparatively expensive than other types such as gate valves. However, the cost is worth it given it is durable and reliable hence ultimately offering necessary cost-effectiveness.
- It offers a fast shut-off mechanism since you only need to turn it to 90 degrees, typically a quarter turn.
- Ball valves require less intensive and infrequent maintenance and repair needs. This allows you to save a considerable amount of money in the long run.
Can you use Ball Valve for Stream?
Yes.
Ideally, a ball valve is a mechanical device for controlling the flow of liquid or vapor in any system.
Since this type of valve provides tight shut-off and predictable control, it means you can use it on steam.
Which Direction should a Ball Valve be Installed?
Ostensibly, the ball in this valve is round.
It thus means there is no specific direction for installing this mechanical device.
However, if you must install a ball valve in a particular direction, ensure it has an arrow cast into the body.
This helps in showing the direction of substance flow.
Can a Ball Valve Fail?
Yes.
This is a mechanical device; thus, it is subjected to failure when exposed to unfavorable conditions.
However, there are several grounds determining ball valve failure.
The common cause of ball valve failure is wear and corrosion.
Over time, gate valves wear out, and corrosion typically makes the disc stick in either an open or closed position.
Also, constant forcing of the handle causes breaking of the stem leading to the disc from the handle rendering the valve useless.
In most instances, failure of this component can occur when the valve fails to seal, and fluid is allowed to pass through in a closed state.
How Durable is a Ball Valve?
Generally, a ball valve is constructed using some of the highly notable robust materials around.
The engineering process of this device also factors in the unforgiving conditions of most of its applications.
Therefore, design construction, in addition to the materials used for manufacturing this device, guarantees excellent durability.
However, the same longevity may vary depending on a wide range of elements.
For instance, the specific type of fluid the ball valve is controlling determines its durability.
Additionally, the mechanical and environmental conditions it is also subjected to determine its precise durability.
What are the Causes of Leakage in Ball Valves?
First off, there are two major types of leakage in ball valves;
- Fugitive emissions &#; This type of leakage leaks from the valve to the atmosphere. It poses an environmental and safety hazard.
- Leakage remaining in the piping system hence posing a potential safety risk to the system itself.
Notably, there are several elements, which cause leakage in ball valves. Some of these causes include the following;
- When the ball valve is not fully closed. This can arise due to debris, dirt, or any other obstruction.
- When the ball valve is not designed to close fully. Some ball valves are designed for precise control during throttling. Therefore, they may lack 100% on/off capabilities.
- When the ball valve is damaged. The damage, in this case, on either the seat or seal can lead to leakage.
- When the ball valve is the wrong size for the project or application. Size incompatibility may lead to leakage.
Can you Get Custom Ball Valve?
Yes.
Different applications require various types of custom ball valves.
Thus if you are working on a custom project, it means you&#;ll require a customized ball valve.
Most reputable manufacturers of this device have different systems and equipment for making any form of a ball valve.
In essence, you need to provide a prototype of your ball valve to the designers.
Afterward, they&#;ll customize the actual ball valve to ensure it meets the specific demands of your application accordingly.
Can you Repair Ball Valve?
It depends on the specific component of the ball valve.
Generally, the only repair you can perform on the ball valve is replacing the packing washer.
However, when the actual valve deteriorates, the ball valve will leak.
In such an instance, you&#;ll need to replace the entire ball valve since it is rendered unrepairable
Can you Install Ball Valve Upside Down?
Installing the ball valve upside down is not recommendable.
Upside down installation seems to deviate the ball valve from vertical is a compromise.
Therefore, it is not ideal for installing this device upside down since it can easily cause dirt to accumulate in the bonnet.
Experts recommend that a ball valve can be installed in any other orientations but not upside down.
How do you Lubricate a Ball Valve?
There are instances where the handle or the ball valve become difficult to turn
However, you can always lubricate the ball valve before connecting it to the piping system.
Here are the steps you need to undertake to lubricate a ball valve successfully;
Ball valve
- Brush a recommended lubricant thoroughly over the entire interior surface of the ball valve before installation.
Allow the lubricant to dry, and then you can connect it directly to the respective piping system.
- Spray another layer of penetrating lubricant around the ball valve handle. Ensure you turn the knob back and forth severally to enable the lubricant to work its way through the ball and crack.
It is the only ideal way of accessing the ball valve inside without cutting through the piping system.
- Apply the lubricant thoroughly over all the internal parts of the ball valve.
What is the Maximum Pressure a Ball Valve can take?
In most instances, the working pressure for high-pressure ball valves is usually psi.
However, this is usually dependent on the size, structure, and sealing material, among others.
Therefore, the maximum working pressure for ball valves can be up to 15,000 psi.
How can you Maintain Ball Valve?
The best way to maintain a ball valve is by making sure it is always clean.
Due to the nature of substances this device controls, there is a tendency for debris to form and accumulate.
Therefore, it is vital to remove this debris occasionally to enhance the efficiency and reliability of the ball valve.
When cleaning the ball valve, here are a few critical steps to always look into;
Ball valve
- Turn the controller to &#;System Off&#; to prevent it from trying to cycle a program.
- Shut off the main substance supply. You should never try to open the valve under pressure since it is dangerous and can be injurious.
- Unscrew and unbolt all the attached components accordingly. These include the solenoid and bonnet, among others.
- Evaluate the ball valve body and remove any pebbles or debris accordingly.
- Ensure the seal is completely clean and free of any abrasions, grooves, nicks, or any related elements.
- Reassemble in reverse order of the manner it was disassembled. Screw and bolt the components to ensure you return the ball valve.
However, the cleaning process may vary depending on the specific type and design of the ball valve you are using.
