Discover how the alternative valve seat makes the Expert's job easier

In another article here on the blog , we have already explained that the Valve Seat serves as a sort of “bed” for the base of the intake and exhaust valves, being responsible for ensuring a perfect fit between the valve and the Cylinder Head , isolating the assembly. Fundamental for all vehicles, it takes on an even more important role in custom engines powered by natural gas for vehicles (NGV), and this is where the alternative Valve Seat comes into play.

This is because, as is usual in the automotive sector, original parts greece phone number list standards validated by large automakers are ideal for traditional engines powered by gasoline, alcohol, diesel and, of course, flex engines. However, we cannot forget that the market also has customized vehicles that use CNG and, therefore, end up requiring special parts and components.

The same applies to custom head projects, for those vehicles that do not have a specific seat model for the application and, consequently, require additional attention from the applicator during the repair or recovery of the heads. It is in this context that the alternative Valve Seat emerges as a valuable ally in the routine of the repairer who wants to provide a quality service and, at the same time, use equipment, spare parts and components of guaranteed origin.

After all, what is an alternative Valve Seat?
To cut to the chase, the Alternative Valve Seat is a component created exclusively to meet the demands for premium quality parts and to supply the custom parts market. Imagine you have an old, collector car and you need to repair the head due to natural wear and tear of the components.

However, the valve seats used on that model are out of stock and you can no longer find a part that fits the head perfectly. Here, the alternative Valve Seat will ensure that the applicator can adjust the size according to the engine's own specifications, all through a simple and practical rectification, since these seats are manufactured with oversizes ranging from 28 to 72 millimeters, sizes capable of supplying practically all engines in the light and heavy lines.

Not to mention that, as high performance delivery is also one of the criteria when evaluating an automotive component, RIO also offers the option of working with these seats produced in super alloy, a superior material, with greater strength and mechanical efficiency, ideal for custom applications and in gas engines.

Oh, and if you're wondering what the relationship is between CNG-powered engines and the need for stronger valve seats, it's worth a quick explanation, remembering that the factory project included the use of fossil fuels for the combustion of the vehicle.

This means that the engine was engineered to have a continuous flow of fuel into the cylinder head, helping to clean the valves and lubricate the assembly. When transitioning to CNG, this flow is interrupted and, without liquid fuel, valve seat wear ends up being more intense and faster, hence the importance of using more powerful seats in the cylinder head!

And nothing prevents these special seats from being used in vehicles with conventional fuel systems as well. Original quality parts are excellent for the assembly plant's project, but that doesn't mean that the alternative Valve Seat can't be even better than these, as it offers greater resistance and superior performance.
