Description

Detroit Diesel E23538844 EGR Valve - Genuine Detroit Series 60 12.7L and 14.0L

The Detroit Diesel E23538844 is a genuine EGR valve for the Series 60 DDEC V. This is the hydraulic electric design, so the electric actuator on top does not move the flap directly, it controls which way hydraulic pressure goes and that pressure opens and closes the valve.

Key Functions:

- Meters exhaust gas back into the intake to bring NOx down
- Electric actuator controls hydraulic pressure to open and close the flap
- Works off ECM command based on load and rpm

Fitment & Specifications:

- Detroit Series 60 12.7L and 14.0L
- DDEC V, roughly 2004 to 2008
- Hydraulic electric valve with electric actuator

Note: Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

Sending exhaust back into the intake cools combustion down, because that gas is already burned and does not burn again, it just takes up room in the cylinder. Lower peak temperature means less NOx. How much goes back in is up to the ECM, and it works this valve to get there. On the DDEC V setup the actuator is electric but the muscle is hydraulic, the actuator just directs the pressure that moves the flap. Not enough flow and EGT climbs along with NOx, too much and the engine loses power and smokes.

Issue Symptoms / When to Replace

Soot is what gets these. Carbon builds up on the flap and seat until it hangs up or stops sealing.

Stuck open gives you low power, black smoke, rough idle and bad fuel mileage. Stuck closed gives you high EGT and EGR flow codes. Either way you end up with a light on the dash and eventually a derate.

Before replacing it, blow out the delta P sensor lines since they plug with soot and throw the same codes. Check the EGR cooler and hot pipe for restriction, and check the actuator wiring and connector. Also make sure the hydraulic supply to the actuator is clean and flowing, since the valve will not move right without it.

Brand Information

Detroit builds this valve to the flow the Series 60 emissions calibration was set up around. The valve, the cooler, the hot pipe and the delta P sensor all work off that same expected flow, so a valve that does not seat or stroke like the original leaves the engine setting flow codes even after the repair.

Installation Notes

1. Find out why the old one failed. A plugged cooler or hot pipe will soot up the new valve the same way.
2. Check the EGR cooler and hot pipe and clean or replace what is restricted.
3. Blow out and check the delta P sensor lines.
4. Look over the hydraulic supply lines and fittings to the actuator for restriction or leaks.
5. Clean the mounting surfaces down to bare metal and check them for cracks and flatness.
6. New gaskets, torque evenly to spec.
7. Reconnect the actuator plug and the hydraulic lines, make sure everything is tight and routed away from heat.
8. Clear codes and check that the valve is moving and EGR flow is reading right before it goes back out.

How to Identify an OEM Part

A genuine unit has the part number and the Detroit Diesel logo cast into the body itself, not printed on or applied with a sticker. Check that the number on the casting matches what you ordered. Aftermarket units usually leave the logo off the casting and put the markings on a label instead.
