About Emission Controls

As a basic manufacturer of emission components, Standard® maintains complete quality control throughout the manufacturing process.

With our expertise and manufacturing processes in place, Standard® offers high-quality parts for all major emission control systems and evaporative emission control systems. As a result, we provide the comprehensive coverage for domestic and import vehicles that professional technicians need to keep cars running clean.

Exhaust Gas Recirculation Valves

To reduce or eliminate the amount of smog-creating pollutants emitted during the combustion process, the Exhaust Gas Recirculation (EGR) valve recirculates a portion of the exhaust back through the process. This results in cooler combustion temperatures, which eliminate the formation of NOx emissions that contribute to air pollution. Every Standard® EGR Valve must pass comprehensive quality testing.

Idle Air Control (IAC) Valves

The idle air control (IAC) valve works with the vehicle's ECU to electrically regulate airflow to the engine to ensure smooth idling. Standard® manufactures Idle Air Control Valves at our ISO 9001 and IATF 16949-certified facilities in Greenville, SC and Reynosa, Mexico, respectively.
