Frequently Asked Questions

How do I know if this valve plate fits my compressor?
Vehicle models alone are not sufficient. You must check the OE number on your existing compressor housing and compare the port layout, port count, and thickness with the new part.
Which engine types is this compatible with?
This part is designed for use with Detroit Diesel engines, specifically the 60 Series and the DD13, DD15, and DD16 series commonly found in heavy commercial vehicles.
What are the signs of a failing valve plate?
Technicians often encounter symptoms such as air leaks, inconsistent pressure buildup, or reduced compressor efficiency due to surface wear or fatigue.
Can this be installed as a standalone part?
While it is a single component, it functions as part of a sealing system. It is best practice to replace it alongside reeds and gaskets during a full compressor overhaul.
What are the OE reference numbers of this part?
1100 330 650 directly replaces Knorr-Bremse OE number K011811.
