Custom engineered critical components to increase MTBF (mean time between failure) of your PUMPS, MIXERS,DRYERS, AGITATORS & BEADMILLS.
We can recommend upgrades in materials of construction utilizing advanced grades of SILICON CARBIDE, TUNGSTEN CARBIDE, METALLIZED CARBON, GRAPHITE IMPREGNATED CARBON & GLASS FILLED PTFE. These upgrades will extend the operating limits of your rotating equipment.
Custom Engineered Work
This VONK CHOKE VALVE was sent in from a chemical plant in Louisiana. End user informed us that this model VONK CHOKE VALVE had a 10 week delivery for a new one. We informed the customer that we could repair the valve by cutting out the worn section and reverse engineer the internal parameters. A new valve neck and flange was machined as a one piece unit. We designed and fabricated an internal plug that would allow for the new section to be welded in place in such a way that all internal clearances were an exact match to how the valve would be in new condition. We also installed a new SILICON CARBIDE internal wear bushing. The VONK CHOKE VALVE was repaired in 3 working days.
