Valve Refurbishment Cost at 99% repairable valves included: a worked example

What does the result look like when repairable valves included reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when planning cylinder valve rebuilds, cryogenic valve service, regulator repair, relief valve testing, or returned asset refurbishment.

The inputs for this scenario

  • Valves sent for refurbishment: 240 valves (unchanged)
  • Refurbishment cost per valve: 38 $ / valve (unchanged)
  • Repairable valves included: 99 % (raised for this scenario; the documented default is 88)
  • Fixed inspection and test cost: 750 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable valve refurbishment cost = valves sent for refurbishment × refurbishment cost per valve × repairable valves included) to the inputs above produces each figure below.
  • At this operating point the engine returns 9,779 $ for total valve refurbishment cost, the number this scenario is built around.
  • At this operating point the engine returns 40.74 $ / valve for refurbishment cost per valve.
  • At this operating point the engine returns 9,029 $ for variable valve refurbishment cost.
  • At this operating point the engine returns 750 $ for fixed inspection and test cost.

How this compares with the baseline

  • Against the tool's baseline example, where repairable valves included sits at 88% and the headline result is 8,776 $, this scenario comes in 11.43% above the baseline at 9,779 $.
  • A figure at this level is achievable when repairable valves included is genuinely sustained, not just peaked for a shift. It assumes one flat per-valve rate; in practice O2-clean service, brass versus stainless bodies, and high-pressure outlets carry different labor rates that you'd need to weight separately.

Results at a glance

  • Total valve refurbishment cost: 9,779 $ (headline result)
  • Refurbishment cost per valve: 40.74 $ / valve
  • Variable valve refurbishment cost: 9,029 $
  • Fixed inspection and test cost: 750 $
