More than 200 EGR valves in stock and tested by the Alfa e-Parts Quality Department

In addition, they have the Alfa HT1 Valve Tester to check the correct operation of the valves and avoid incorrect warranties

Alfa e-Parts, the newest brand of electrical and electronic parts that is part of the European Division of BBB Industries (BBB), has put the focus on EGR valves, a product family that has more than 200 part numbers in its catalog, and announces an increase of more than 80 new spare parts for this year 2023. You can access all the technical information in the new Alfa e-Parts EGRs brochure.

The EGR valve is designed to reduce harmful gases, specifically NOx. They are found in both petrol and diesel engines, although their effect is more powerful in the last as it emits more of the referred gas. It’s located between the intake manifold and the exhaust, and allows part of the exhaust gases to return to the combustion chamber through the intake manifold to be re-burned.

There are two types:

• Pneumatics: operate on the basis of the vacuum generated by the intake manifold and the force applied on a spring that opens and closes according to the pressure exerted. The amount of vacuum received by the valve is regulated by an electric solenoid.
• Electronic: allow a more precise control of the amount of exhaust gases recirculated to the intake. This type of valve does not operate from vacuum, but is electrically controlled by the vehicle’s engine control module.

These are some of the most common failure symptoms:

• Emission of harmful gases, like NOx.
• High fuel consumption.
• Loss of engine power.
• Vehicle jerking.

Alfa e-Parts reflects the philosophy of BBB Industries, betting on a best-in-class electronics developed with the latest technologies. They achieve this thanks to their own laboratory and a Quality Department with a team of engineers who verify the quality of all their products. For example, the following quality tests are carried out for the EGR family:

• Leakage test.
• Vibration test.
• Corrosion test.
• Temperature and humidity test, temperature shock test, high/low temperature storage test.
• Durability test.
• Exhaustive dimensional, material, electrical consumption control matching OEM specifications.

In addition, Alfa e-Parts is so confident in the quality of its products that it provides its customers with a tool to check the operation of electrically operated EGR and throttle valves. The Alfa HT1 Valve Tester, patented and unique in the market, performs test using OEM parameters for each of the Alfa e-Parts EGRs has in its catalog.

In these tests, different component positions and speeds are tested. Unlike other EGR tests, the Alfa HT1 Valve Tester is not limited to testing if the component moves correctly within the OEM’s specifications, but as well tests if the information sent to the engine control unit is appropriate to its specifications.

This innovative tool from Alfa e-Parts is a technical support for the customers to check the function of valves and thus help diagnose valve system failures. This helps to avoid unnecessary claims due to incorrect warranties. Alfa e-Parts quality is present before, during and after the sale of the product.
