Exhaust Gas Recirculation Valves
Delphi Electronic Diesel Exhaust Gas Recirculation (EGR) Valves recirculate metered amounts of exhaust gas into the engine’s intake system
to help limit the formation of nitrogen oxide (NOx) emissions. Delphi offers a
family of diesel EGR valves based on a proven electronically actuated
diesel exhaust gas recirculation valve technology.
Delphi Electronic Diesel Exhaust Gas Recirculation Valves are available
with single poppet, dual poppet and butterfly valve designs to help meet all
ranges of flow requirement for diesel engines. They are available with
torque motor or direct current (DC) motor actuators to help meet individual
customer requirements for force, response, cost and leak.
Benefits
Robust valve design provides carbon resistance, durability and long life,
high quality and engine control module controllability.
High opening and closing force actuators minimize impact of corrosion and
help provide high quality, durability and long life. They have ECMcompatible drivers. Delphi offers a range of actuators to meet customer
application requirements.
Fast valve opening and closing response time enhances engine control
module controllability and helps lower emissions as a result of the
reduction in exhaust gas lag time.
Stainless steel valves and components provide robust performance and
resistance to corrosion, high temperatures and wear.
Modular valves offer design flexibility to meet a full range of customer
requirements.

with Torque Motor
Typical Applications
Delphi Electronic Diesel Exhaust Gas Recirculation Valves are
designed for diesel engine programs targeted to meet future exhaust
emissions requirements in Europe, North America and Asia. They are
designed for both highway and off-highway applications.
