Exhaust gas recirculation

Technical specifications

Application

Housing for the valve in the exhaust that recirculates exhaust gases in the ‘Exhaust Gas Recirculation’ (EGR) system. This method of reducing NOx emissions is used in internal combustion engines.

Advantages

• Precision cast piece SiMo or Ni-Resist
• Material can withstand high temperatures
• Savings in material costs

Advantage of the CIREX casting process

SiMo and Ni-Resist are difficult to use in thin-walled cast pieces. CIREX’ casting process is  very stable. Moreover, nearly any type of steel alloy can be cast. The design of the cast piece is suited to this. Components cast in SiMo or Ni-Resist are special heat-resistant steel alloys that are not affected by corrosive, hot exhaust gases.
