What is Carbon Steel Ball Valve?
These are ball valves that are made out of carbon steel material.
Carbon steel is different from other materials used in industrial ball valves; this is mainly attributed to their appearance.
Similar to stainless steel, carbon steel is also made from metal alloys.
There are minor variations in quality.
They do have significantly lower resistance to chemicals and melting point compared to other materials.
They have higher levels of malleability and heat distribution due to their high carbon composition.
Carbon steel ball valves can be used in completely shut or fully open roles.
This is because they are intended to use inefficient output and robust applications.
Carbon Steel Ball Valve
What are the Applications of Carbon Steel Valve?
Their features make them versatile, hence usable in a wide range of applications.
They are more robust and durable because of their carbon composition.
This makes them well suited for applications that generate high amounts of pressure.
They will not bend or break easily in such applications. Such applications are:
Hydraulics-oriented applications and processes.
Liquids with corrosive tendencies like water and other chemicals have minimal effect on carbon steel ball valves.
Carbon steel ball valves treated with paint or taken through ferromagnetic processes are corrosion resistant.
Power and chemical plant applications.
There is extensive use of carbon steel ball valves in these areas because of their leak and pressure spike prevention properties.
Additionally, carbon steel ball valves hinder the occurrences of reverse flow in such processes.
What are the Components of Carbon Steel Ball valves?
The body or shell: This component is made of carbon steel and can work under a maximum temperature range of between 400° F and 450° F.
The main purpose of this component is to keep all carbon steel ball valve units together and safe from external hazards.
The Ball: This is one of the most important components of the carbon steel ball valve.
It’s a spherical piece that has a hole at its center.
Carbon Steel Balls
The Trim: The seat, stem, sleeves, and disk parts of the carbon steel ball valves are collectively known as the trim.
They work in tandem with the actuator component to fulfill designated functions.
Trim of Carbon Steel Ball Valve
The Packing: This component is located between the stem of the carbon steel ball valve and the bonnet component.
Its main function is to prevent leaks.
It should neither be too tight nor too loose.
Proper placement of the packing ensures no damage is caused by leaks.
How do Carbon Steel Ball Valves Work?
Carbon steel ball valves work by the same principles as other ball valves.
They have a ball component that is perforated, pivoting, and hollow.
A handle is used to control flow through said ball component.
The handle’s rotation turns the ball to an axis that is perpendicular to the direction of flow thereby stopping fluid.
Simply put, the carbon steel ball valve is closed when the ball hole is pivoted at 90°.
The valve is considered open when the hole is facing a similar direction to that of flow.
How do you Maintain Carbon Steel Ball valves?
Carbon steel ball valves are the least expensive valves to maintain.
They only need regular valve cleaning and a bit of cleaning, lubrication, and checking and replacing worn parts, e.g., O rings.
The ball component has difficulty turning when there is a build-up of debris or corrosion and dried-out lubrication.
You ought to be careful not to apply excessive force on the carbon steel ball valve handle as it can break.
This can render the valve inoperable. In such instances, a replacement or repair should be done.
You also need to conduct regular inspections to check for leakages and attend to them immediately.
What are the Advantages of Carbon Steel Ball Valve?

Top Entry Carbon Steel Ball Valve
- Three-Piece Carbon Steel Ball Valve
3-Piece Carbon Steel Ball Valve
These classifications are made depending on how the carbon steel ball valve components are manufactured and assembled.
All the above types operate in similar ways.
Other than the body, carbon steel ball valves can be classified in other ways, i.e.,
Full Port/Bore Carbon Steel Ball Valve: These carbon steel ball valves have large and oversized balls.
The ball hole diameter is equal to the pipeline diameter.
This reduces friction loss by ensuring that flow is not restricted.
These carbon steel ball valves are suitable for applications where free flow is required.
Reduced Bore/Port Carbon Steel Ball Valve: In this type of carbon steel ball valves, the ball component has a smaller diameter than the pipes.
V Port Carbon Steel Ball Valve: This type of carbon steel ball valve is well suitable for applications where stable flow control is required.
It allows for even percentage and linear flow since opening begins at the smaller end of the V-shaped ball.
This type of carbon steel ball valves requires very strong construction.
The controlled media has a significantly high velocity that may damage other valves.
What Temperature do Carbonate Steel Valves Work at?
The maximum temperature rating for carbon steel ball valves is 105° Celsius.
The minimum temperature rating can be lowered even further by the use of thermoplastic inserts such as RPTFE.
The range of operation is between 0° Celsius and -10° Celsius.
How do you Make Carbon Steel Ball Valve Tight?
After extended use, carbon steel ball valves may experience leakages.
They have an adjustable packing nut that you can tighten to mitigate the problem.
You should conduct regular inspections to ensure that the packing nut is not tightened past its limit.
How do Carbon Steel Ball Valves connect to Piping Systems?
The general rules of thumb for connecting carbon steel ball valves to piping systems are as follows:
- You should ensure that the handle direction is perpendicular to the pipe when in the closed position.
- You should ensure that the carbon steel ball valve is installed in a manner that works and is safe.
For example, the carbon steel ball valve sticking out may be a hazard as someone may suffer injuries by bumping into it.

ATEX (Atmospheres Explosible) provides relevant approvals and norms against which the carbon steel ball valves are tested.
Carbon steel ball valves in this section are tested as per API 607 regulations.
Additionally, they are CE PED/97/23/EC- C III and ATEX 3 GD 94/9/EC approved.
How does Carbon Steel Ball Valve compare to Gate Valve?
Carbon steel ball valves are well suited for applications that involve liquids and gases because they provide firm seals.
Gate valves, on the other hand, are best suited for applications that involve viscous liquids, e.g., oil.
This is because they are highly likely to have leakages than carbon steel ball valves.
Carbon steel ball valves are often manually controlled and considerably smaller in size than gate valves.
Carbon steel ball valves are well suited for active media flow control.
Whereas, gate valves are better suited for high temperatures and pressure.
Gate valves are also suitable for fluctuating temperature and pressure applications.
Carbon steel ball valves are pricier than gate valves.
But they offer efficient operation and are worth the buck.
