Valves are vital to engine parts. Not only this, but we also use them in other types of machines and equipment. The purpose of valves is to balance the flow of water or air inside a piece of machinery/equipment.


Centrifugal machines are quite versatile. You can use them for almost any kind of polishing. They can polish, deburr, clean, or finish nearly any type of metal in a short amount of time. Centrifugal barrel finishing machines are quite incredible. And Inovatec Machinery is the right place to get yours today.

You may use this machine for all of your valve polishing needs. And since valves are generally small, the device can easily give it an even, smooth finish.


Another name for this machine is the vibratory tub finisher. This machine is also perfect for valve polishing. Although this machine is more suitable for more significant parts, there’s no issue using it for valves too.

To add, you can also use the trough finisher for camshaft and crankshaft polishing when it’s sitting idle. The machine has added suspensions to keep the vibrations under control.

Valve Polishing of Different Materials

Every engine has valves. There isn’t an engine that can work properly without a valve. Valves are in charge of maintaining the flow of exhaust gases. They also control their intake. As such, valves need proper polishing before you can install them.

To polish an engine valve, use a centrifugal barrel finishing machine. It will give you the fastest results. Simply load in your valves and the right media, and you’re good to go.

Diesel engines are quite different from petrol and gas engines. Diesel engines have a different system and components. For this reason, you have to be very careful about what media you are pairing with turbo-diesel intake valves.

You should use a trough vibratory finisher for this task. The machine has a big tub that can accommodate multiple parts at the same time. Plus, the process is cheap and efficient.

Performance parts make good use of titanium. Automotive fanatics love using titanium for any of their automotive parts. It also applies to titanium valves. Titanium valves are lightweight yet durable. These qualities make them the best choice for performance vehicles.

To polish these valves, you must invest in centrifugal barrel finishing machines. Yes, this option is expensive, but so are titanium valves. Choosing a cheaper option

Polishing stainless steel is just like any other material. To clean this, you may use either a trough vibratory machine or the centrifugal barrel machine. The final finish will be mirror-like.

Just like any other vehicle, motorcycles also have valves. Motorcycle valves are small, but they have to be tough to take the brunt of the revving engine. It is why it’s so crucial for valves to be polished before you go ahead and install them.

If your budget allows it, so choose a centrifugal barrel finisher. If not, you can also select the trough vibratory finisher.

Automotive valves are valves that insert into a vehicle’s engine. You can find these a variety of shapes and sizes. Cast-iron, forged steel, and sand casting aluminum are just some of the metals used to make pistols.

To make the most out of automotive valves, choose the right mass finishing machine. The best option is Inovatec’s centrifugal barrel finisher. You may also use more specialized machines, such as the Zero Gap CF series for better results.

Vibratory Tumbling Media

No matter what you’re polishing, you can’t get good results without polishing media. The basis of polishing media is different from burnishing or deburring media. It is because polishing media is not as harsh as other types of media.

For valve polishing, always go for polishing media. Plastic media and porcelain media are among the most commonly used. To suit your requirements, you can select media in many shapes and sizes. But in case you don’t know where to start, Inovatec’s technical team is at your disposal.

Valve Polishing – The Definitive Guide

Valves are essential parts of engines as well as other types of equipment.

Valves control how much liquid or fluid goes into an engine.

If you’re someone who deals in engines, you will require valves at some point.

Polish any valve properly to avoid hindering its performance.

You will find the best polishing solutions, only at Inovatec.

The following is a guide on some questions you may have about valve polishing machines and the process.

1. What Type Of Polishing Media Is Most Suitable For Valve Polishing?

It doesn’t matter what you’re polishing. To get the desired result, you will need to use polishing media.

Polishing media is generally less abrasive than other types of media, such as deburring media.


1.1 Porcelain Media

Porcelain media is a particular type of ceramic media that gives your valves a subtle finish along with polish.

It is a sturdy type of media and can clean even the most intricate parts of your valves.

Porcelain media gives you a mirror-like, uniform finish.

You can purchase this media in a variety of shapes, such as a sphere, cylinder, tristar, etc.



1.2 Plastic Media

Plastic media is quite popular because it is durable and lightweight.

You can also get these in many shapes, such as cones, pyramids, tetrahedrons, and more.

Thus, it’s vital to choose the right media for your needs. It will avoid your media from getting stuck inside the valve.

With plastic media, you cannot receive a shiny finish.

If, at any point, you want assistance with choosing the right media, contact Inovatec’s technical support team.



2. Which Valve Polishing Machines Are Offered By Inovatec?

Polishing valves after they are manufactured improves their efficiency.

For valve polishing, Innovatec offers two types of machines. Depending on your needs, you may use any of them you’d like.


2.1 Trough Vibratory Finishing Machine

This machine also has another name: a tub vibratory finishing machine. It is an incredibly useful device.

To add, you can use it for any of your valve polishing needs.

The machine has a large tub made for large and intricate workpieces. Nevertheless, it gives sleek and impressive results.

You can rely on trough vibratory machines for polishing:

  • Turbo diesel intake valves
  • Motorcycle engine exhaust valves
  • Stainless steel intake valves



2.2 Centrifugal Barrel Finishing Machine

The centrifugal solution is a multi-purpose finishing machine. It’s very prevalent in the mass finishing industry.

The machine uses a lot of energy. It’s a heavy-duty and high-quality finishing equipment. To add, it’s fast as a bullet.

With this machine, you can polish:

3. What Factors Should Be Considered When Choosing a Valve Polishing Machine?

When selecting valve polishing equipment, keep the following in mind:

  • Strength of the Polishing Machine

The strength of a machine determines the weight it can sustain. From this, we can find out its efficiency.

You should not be overloading any of the machines with the contents. It can render an inefficient finishing operation.

  • Size of the Polishing Machine

Size is also another major factor to consider when choosing a machine.

Make sure that the machine you are choosing can accommodate the valves you wish to polish.


4. What Are The Benefits Of Polishing My Valves With a Trough Vibratory Finisher?

Here are the benefits of using a trough vibratory finishing machine:

  • Fast-Paced Polishing Cycle

Vibratory machines are rapid and can finish any metal in a minimal amount of time.

This trough vibratory machine is no exception.

A vibratory machine can do valve polishing in just a matter of minutes, depending on your requirements.

  • Shape Retention

Another benefit of using a truth finisher is because it retains the shape of the valve.

Rest assured that there will be no part-on-part contact, which can potentially damage the valves.


5. How Can I Polish My Valves Without Damaging Them?

One of the main points about valve polishing is that they sustain no damage during the process.

You want to make sure that none of the valves gets damaged or dented during the process.

Here’s what to consider:

  • How suitable the machine is
  • The choice of media
  • Part retention time – For example, too much polishing can lead to undesirable results. Thus, you not polish valves for the recommended amount of time
  • Polishing compounds – Polishing too little or too much can lead to an ineffective and expensive process

Here’s a helpful guide in regards to different valve materials:

Turbo diesel intake valve: To polish this valve, use a trough vibratory finisher with suitable polishing media for the best results. It will also result in little to no damage.

Motorcycle engine exhaust valve: If your budget allows it, use a CBFM. If not, a tub vibratory machine will work too.

Automotive valves: To deflect damage, choose a centrifugal barrel finisher with the adequate polishing media.

To best results, you can also invest in the Zero Gap CF series.

Titanium intake valve: If you want to avoid damage, select the CBFM solution with the right polishing media.

Engine valve: Select a centrifugal barrel finishing machine with the appropriate polishing media to avoid damage.

Stainless steel intake valve: For these valves, you may use a trough vibratory finisher or a tub vibratory finishing machine.


6. Should I Use a Centrifugal Barrel Finisher Or a Trough Vibratory Finisher For My Valve Polishing Operations?

Both machines give desirable results and are perfect for any type of valve polishing.

However, a centrifugal barrel finishing machine is especially suitable for small parts. It’s also pretty fast-paced.

Because valves are small parts, a CBFM uses its strength to its advantage.

The machine is generally made for large parts, but it works just as well with small valves.

Thus, your final choice needs to be practical and suitable for your purposes.

7. How Does a Centrifugal Barrel Finisher Efficiently And Effectively Polish Valves?

This machine is a heavy-duty, fast-paced piece of equipment. It uses centrifugal force (G-force) to its advantage.

The G-force allows the machine to apply intense pressure between the valves, the polishing media, and the polishing compound (if used).

This high-friction process results in sleek and even finishes on the valve parts.

When using a CBFM, keep the following in mind to make the process as smooth as possible:

  • Do not overfill the barrels
  • Set the processing cycle to a suitable time—not too long or too little
  • Where needed, use polishing compounds
