EGR Valve Systems
Design, validation and manufacture of
exhaust gas control valves for on and off highway vehicles
Product Overview
GT is at the forefront of emissions control technology, with proven EGR systems already operating successfully in the field. We have also developed next-generation solutions that meet international emissions standards, including Euro 6, Tier 4 and pPNLT.
EGR Valves (Exhaust Gas Recirculation Valves) precisely measure a proportion of the exhaust gas which is then passed through a cooler and recirculated back into the combustion chamber. This reduces the NOX emissions.
The proven GT EGR system provides a reliable means of precisely controlling the exhaust gas flows in a very hostile and high temperature environments.
More advanced options of exhaust gas re-circulation systems can be offered including cooler by-pass systems.
