intervals and reduced maintenance cycles.
Reducing Downtime: The Hidden Profit Driver
Every hour of unplanned downtime can cost a plant thousands—or even millions—in lost production. Lead times for new specialty valves, especially large or custom-engineered units, can stretch from 16 to 40 weeks.
In contrast, an experienced HVOF repair facility can strip, coat, and rebuild a valve in a matter of weeks, restoring it to service well before a replacement could even ship. That speed translates directly into bottom-line impact: faster recovery, steadier production, and fewer emergency workarounds.
Case in Point: Oil & Gas Slurry Service Valve
Consider a 10-inch trunnion-mounted ball valve operating in an upstream oil production facility handling abrasive slurry. The valve began showing signs of seat and ball wear due to sand-laden flow—leading to leakage and reduced sealing integrity.

A new OEM valve carried a price tag of $45,000 and an estimated delivery time of 28 weeks. Instead, the plant opted for HVOF repair. The ball was stripped, re-coated with WC-Co-Cr, and precision lapped to restore tight sealing. The total repair cost was $14,000, with a turnaround of 4 weeks.
Even more impressive: after 18 months of operation, the HVOF-repaired valve showed minimal wear, outperforming the expected service life of the original. The result was a TCO reduction of over 60% and improved reliability across the system.
A Financial Strategy, Not Just a Maintenance Task
Forward-thinking maintenance managers understand that cost optimization doesn’t always mean cutting corners—it means extracting maximum value from every asset. By adopting HVOF repair as a standard practice for valve refurbishment, plants can:
