Shoe Component for Rotary Valve

Reason to Consider Surfacing

Wear on shoe component of rotary valve results in leakage in the closed position.

Issues

Reduce wear to eliminate material wastage and reduce maintenance costs.

Option

OEM sends parts directly to ASB Industries for processing. Chrome oxide is applied together with a 0.002 to 0.004 in. (0.05 to 0.1 mm) NiCr bond coat using the Rokide combustion process to apply materials in a rod form. C2O3 coating thickness is approximately 0.015 in. (0.38 mm). The shoe is hard-wheel ground to achieve required finish dimensions, and is finish ground using a diamond wheel to an approximately 20Ra micro-in. (0.5 m) finish.

Benefits

  • Ceramic coating easily diamond ground to oem specifications
  • Extends the service life of the shoe by 8 to 10 times that of the
    uncoated part.
  • Customer reduced the costs of purchasing and shipping new replacement components to a remote location.
