For all valves (Stainless Steel, Nimonic, Duraspindle) reconditioning of the combustion face and seat, including W-type, is the most attractive and cost-effective solution when carried out properly. The repair process of damaged components (signs of blow-by, wear or corrosion) needs to give them equally (or even better) characteristics to those defined in OEM’s specifications, otherwise, it may result in component failures or shorter life expectancy.

KIMI has developed the most advanced procedure after years of research and investment in order to ensure that the parts which supplies to its customers always meet or even exceed OEM’s standards beyond any doubt.

This procedure includes:

  • Material composition’s identification, is a step very crucial during initial inspection. Exhaust valve discs repaired in the past with the wrong filler material can cause premature failure of the next recondition
  • Metallurgical examination
  • Geometrical evaluation through 3D scanning
  • Rebuilding performed by AI-driven welding robotic systems offering a fully automated service from start to finish with fine-tuned welding parameters, consistent & high-quality welds, free of  thermal stresses
  • Pre-machining and post-machining on multi-axial CNC turning machines

Exhaust valve and seat should be built up and not just machined in order dimensions to be fully restored

KIMI, based on the above, offer a full-rebuilding, premium quality service with a lot of benefits, such as:

  • Highly adaptable reconditioning service for all valve material types and maker’s specifications (Duraspindle, Nimonic, Stellite) considering inherent base material flaws
  • Improved performance, service lifetime, and quality equal to new
  • Cost-effective service beyond compare through our cutting-edge AI robotic systems
  • Unmatched reduced downtime through 24/7/365 operation
  • Stringent quality control protocols and checks by PCN Level II certified personnel. Issuance of final reporting
  • Enhanced traceability with the KIMI logo and order number stamp
  • Cost breakthrough reconditioning service setting new market standards

Finally, as an alternative to our rebuilding service, we offer exhaust valves and seats on exchange basis or for sale.
