EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)

An EGR valve is an emission control component designed to redirect a portion of exhaust gases back into the intake system. This process lowers combustion temperatures, reduces nitrogen oxide emissions, and helps the engine meet environmental standards.

The valve is installed between the exhaust and intake systems and operates together with the engine control unit, pressure sensors, and fuel injection system. In modern vehicles, EGR valves may be vacuum-controlled or electronically actuated and may include an integrated cooler.

A faulty EGR valve may cause power loss, increased fuel consumption, unstable idle, excessive smoke, intake contamination, engine fault codes, or limp mode activation.

Our catalog includes EGR valves for many vehicle brands. Available options include genuine factory units, reliable aftermarket replacements, and tested used valves without housing damage. Vacuum and electronic versions, cooler-equipped assemblies, and units for petrol and diesel engines are available.

Used parts are inspected for sealing integrity, actuator function, housing condition, and connector reliability.

Selection is available by VIN number, engine code, part number, EGR system type, and vehicle year. Replacing a faulty valve restores engine efficiency, reduces emissions, and clears control system errors.
