Valve Refurbishment Cost at 63% repairable valves included: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop repairable valves included to 63%, then walk the calculation through step by step. Estimate valve refurbishment cost from valve count, refurbishment cost per valve, repairable share, and fixed inspection or test charges.

The inputs for this scenario

  • Valves sent for refurbishment: 240 valves (held at the documented default)
  • Refurbishment cost per valve: 38 $ / valve (held at the documented default)
  • Repairable valves included: 63 % (the input this scenario stresses; the baseline uses 88)
  • Fixed inspection and test cost: 750 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable valve refurbishment cost = valves sent for refurbishment × refurbishment cost per valve × repairable valves included.
  • Total valve refurbishment cost works out to 6,496 $ at these inputs, and this is the headline figure for the scenario.
  • Refurbishment cost per valve works out to 27.07 $ / valve at these inputs.
  • Variable valve refurbishment cost works out to 5,746 $ at these inputs.
  • Fixed inspection and test cost works out to 750 $ at these inputs.

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 25.98% below the baseline at 6,496 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to repairable valves included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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.
