AI-Driven Exhaust Valve Rebuilding for MAN B&W, WinGD and Mitsibishi UEC Engines

Experience KIMI’s Revolutionary AI-Powered Rebuilding Service

2-Stroke exhaust valve spindles are operating more and more under extreme conditions. Despite being made of special materials and alloys, valve failures such as blow-by, corrosion, and abrasive wear are common issues for exhaust valve spindles of MC-RTA and UEC engines, mainly due to inconsistent, substandard repair processes and insufficient welding technology.

KIMI’s AI-Driven Exhaust Valve Rebuilding Service is available for exhaust valve spindles of the following 2-stroke marine engine types:

  • MAN B&W MC, MC-C, MC-CE, MC-C8, ME, ME-C, ME-B and ME-GI series
  • Sulzer / WinGD RTA, RTA-T, RT-flex and X-series engines
  • Mitsubishi UEC-LS, UEC-LSE and UEC-Eco engine series

Our AI-powered rebuilding process is fully adaptable to various spindle materials, including Duraspindle®, Nimonic®, Stellite-faced and other OEM-approved configurations, ensuring compliance with Maker specifications and restoring components to the highest quality standards.

The need for adequate and reliable rebuilding services that adhere to Maker’s material and reconditioning specifications is critical in mitigating the risk of catastrophic failures.
