In 1997, shortly after opening our Gladstone office, HMA was presented with a recurring plant shutdown issue at a major alumina refinery in central Queensland.

A Fisher body valve was failing at a critical fl**ge wear point. The original design was hard-faced with Stellite, yet the valves were lasting only a matter of months โ€” with each failure triggering costly plant downtime.

Working closely with site reliability engineers, HMA engineered a smarter solution.
We extended the valve body to eliminate the primary wear point and incorporated advanced internal linings, ceramic bearing protection and improved stem packing arrangements.

The modified valve was returned to site ready for actuator installation โ€” fully re-engineered for durability.
The result?
Valve life was extended from months to years.

What had been a persistent shutdown risk became a celebrated reliability improvement. Over time, multiple valve sizes were modified, with several units refurbished each year โ€” delivering significant savings in maintenance costs and lost production.

Itโ€™s a reminder that innovation doesnโ€™t always mean reinventing everything. Sometimes itโ€™s about understanding the failure mechanism, partnering with the client, and engineering the wear out of the system.
60 years on, that mindset still drives HMA.
