Custom Remanufactured Diesel Engine Valves
Engine Valve Manufacturing
The remanufacturing process begins with valve core that is usually provided by our customers. As you disassemble the engine heads, simply drop the worn engine valves into shipping crates rather than into a scrap bin. There's no need for you to do any cleaning, inspecting, or sorting of the valves. Just ship the valve core to us.
Each engine valve may be subjected to as many as 18 different manufacturing operations. Throughout these operations, we use some of the best gauging and measurement equipment including digital and laser micrometers, optical comparator, eddy current and ultrasonic detectors, profilometers, dial indicators and digital hardness testers.
Several key processes such as hard chrome plating of the engine valve stems and grinding of the faces are computer controlled. These operations are started, run, monitored, adjusted, and stopped automatically by computers. This ensures that your parts are sized accurately, consistently, and efficiently. Automating operations such as these enables us to easily customize engine valves to your exact specifications.
