Nearly 30 years of conical valve production has made us an expert in dealing with abrasive slurry in corrosive environment. Knowing the application details such as miller number, corrosion, expected valve life etc. we carefully select material grade, either wear resistant iron or low alloy steel with high or medium hardenability. Given the lifespan of the product, our material-heat treatment specialists gives suggestion on surface hardening process so does the right type of valve rings advised by rubber engineer.
The followings are examples of successful cooperation with original pump manufacturer:
Application | Problem | Solution | Result |
Long distance transportation | Partial wear on conical valve | Change the four-claws structure into one shaft | Even wear on sealing surface and valve life increases 30% |
Gold refinery | Frequent unplanned shutdown due to valve damage | Apply surface welding deposit on sealing surface | Increase valve life to more than 2000 hours |
Nickel and cobalt refinery | Cavitation damage on valve sealing surface | Apply cavitation resistance alloy on sealing surface | Increase valve life more than 45% |
Bayer Alumina | Frequent unplanned shutdown due to valve damage | Decrease valve weight by 10% | Increase the valve by 20% |
