EGR Valves

As its name suggests, the exhaust gas recirculation valve – EGR valve for short – recirculates finely metered quantities of exhaust gas to the engine intake system. By simply altering the chemical makeup of the air entering the engine and thus lowering the temperatures in the combustion chamber, it reduces the production of NOx for a much cleaner, more efficient exhaust. With so much at stake, you’ll want to fit a quality brand with proven OE technology…just like ours.

Exhaust Gas Recirculation Valve OE technology

With over 20 years OE EGR system expertise, our valves are fitted as OE to millions of vehicles worldwide. We bring this same expertise to the aftermarket, with a comprehensive range including rotary and linear configurations, all based on our proven electronically actuated EGR valve technology.

Built for tough conditions

Because of the harsh environment of its location on the intake manifold, we only use the highest quality materials such as robust stainless steel valves, high temperature internal components and RTV silicon seals. The result – a quality EGR valve, highly resistant to extreme heat, contamination, corrosion and wear.

Precision engineered

Even the smallest of differences in the shape of the valve head can affect both valve leakage and flow metering, leading to increased fuel consumption, carbon build-up and decreased vehicle performance. That’s why every Delphi EGR valve is precision engineered to match the OE design.

Super quick response time

All our valves feature fast opening and closing response times for enhanced engine control and lower emissions from reduced exhaust gas lag. The high opening and closing force also helps to minimize the impact of corrosion, ensuring a longer lasting part.

Resource Highlights

In this article, you will find out how Delphi' EGR valve technology helps the world’s leading vehicle manufacturers meet both current, and future targets for NOx.

In Europe, the Euro 6c and Euro 6d TEMP specifications, came into force in September 2017. And as with every change, the rules have become increasingly stringent. Whilst the limits are exactly the same, under the updated standards, new vehicles must demonstrate that they can meet original targets on NOx and particulate matter under even harsher test conditions. That means on the road as well as in the lab - a world-harmonized testing procedure called WLTP for Euro 6c and Real Driving Emissions (RDE) testing for Euro 6D TEMP.

The role of the EGR valve in NOx reduction.

These tests have meant that NOx reducing technologies are becoming increasingly important. One of these being the exhaust gas recirculation valve, or EGR valve for short. Integral to the vehicle’s engine management system, it allows a precise quantity of exhaust gas to re-enter the intake the system, effectively changing the chemical makeup of the air entering the engine. With less oxygen, the now diluted mixture burns slower, lowering temperatures in the combustion chamber by almost 150°C, and reducing NOx production for a cleaner, more efficient exhaust.
