Powertrain: High Pressure EGR Valve Solution
Handling Leakage and Friction
A high pressure (HP) EGR Valve is a very demanding application for dry running sealing solutions due to the close position to the exhaust tract. Along with a high temperature range of -40°C to 180°C, the seal must withstand sulfuric acid (diesel engine) while ensuring low and constant leakage and friction as well as compensate for misalignment of the shaft. As a result of precise manufacturing process and customized material blends, our OmniSeal® and Rulon® shaft sealing solutions become maintenance-free to perform consistently over lifetime of the valve without additional lubrication.
