Valve Marking Techniques You Can Use
Many marking methods are suitable for marking valves. However, choosing the best method for your production relies on various factors. Let’s discuss some valve marking processes you can use for your projects below;
Dot Peen Marking System

Dot peen is a permanent marking process that creates small dots using a pin on valve parts. These dots or markings are highly readable. Consequently, dot peening is a common and essential valve marking process in diverse industries.
Why Dot Peening is Suitable for Valve Marking
Dot peening is a very popular process in valve marking. This is because of its fucntions and how it makes valve marking easy. Below are some reasons why dot peening marking process should be your preferred plan.
· Production Speed
The dot peen machine has a quick and easy installation process. Aside that, it is a effective and efficient process and can mark valve parts in extremely short amount of time. However, this depends on the experience of the designer.
· Permanent and Readable Markings
These are reasons why many industries prefer using dot peen machines for valve marking. Dot peening can create deep permanent marks that are long-lasting and can withstand harsh conditions. The markings are also readable and of high quality despite having a low operational cost.
· Efficient Marking Operation
Dot peening marking is an efficient marking operation due to the ease of operation associated with most dot peening machine. For example, when you look at the recommended HS-DP01-R Dot Peen Part Marking Machine with Rotary Device, its flexible rotary head allows part circle surface marking. This enables the ability to inscribe a part without adjusting the machine. Other machines recommended are also easy to operate.
Dot peening marking has many advantages. However, it also has its disadvantages. For example, it subjects the valve to mechanical stress, which can be a problem if you are working with a material averse to that. Also, when used, there is an issue with noise pollution.
Nevertheless, it is an effective and efficient valve marking method.
Laser Engraving

Laser Engraving is a process that uses a laser beam to change an object’s surface. It uses high heat associated with a laser beam to vaporize and remove part of the valve to create the final image.
Why Laser is Suitable for Valve Marking
Laser engraving is an effective valve marking process for the following reasons:
· Permanent and Highly Readable Markings
Laser engraving is a permanent, non-contact, abrasion-resistant laser marking process compatible with many materials.
· Highly Readable Markings
Laser engraving results in markings of very high readability. Consequently, it is an ideal valve marking method with utmost popularity.
· It is Production Efficient
Laser engraving machines are effective in low volume and high volume jobs. However, you must consider the type of laser marking machine before beginning the process.
Limitations of Laser Engraving
The main limitation of using laser engraving in valve marking is that laser engraving machines are costly. Also, the use of laser engravers exposes the materials to thermal stress.
Valve Tagging Process

A prevalent method of valve marking is using metal tags. Valve tags enable the manufacturer to track products even in a very harsh industrial environment.
These valve tags can withstand high temperature, acids, cleaning process, and prolonged weather exposure even in extreme situations.
Procedures for Valve Tagging
There are various ways of making metal tags for the valve marking process, below are some of these processes
Embossing
Embossing is also a stamping process that raises and elevates the design or relief on the metal tags. This process involves matching opposite rollers dies or passing the metal between roles for a particular pattern. Embossing creates a 3-dimensional effect on your metal tags which is suitable for valve marking.
Stamping
Stamping is another procedure of tagging on metal plates. Stamping involves marking the metal part by pressing on a mold bearing the indent. This process causes a permanent deformation to the structure of the metal. It causes an alteration in the crystal structure of the metal.
Screen Printing
Instead of embossing or stamping, printing applies durable and long-lasting ink to form suitable valve tags on the metal plates.
Why Metal Tag is Suitable for Valve Marking
Valve tagging is an effective valve marking process for the following reasons:
· It is Environmentally Compatible
Metal tags can withstand difficult situations that these valves go through, such as acid bath, corrosion, and heat.
· Durability
Metal tags on the valve are durable and last for a very long time without little or no deformation. It is not easy to alter metal tags that are permanent on the valves.
· It Provides Many Option of Use
There are varieties of metal tags due to the various colors, sizes, and styles. This variety enables you to tailor the type of valve tags you need for a specific environment.
