Summer is turnaround season. It’s when the control valves that ran hard all year finally come apart on the
bench — and it’s exactly when the parts to put them back together are hardest to get. A Fisher rebuild that
should take days can stall for 12 weeks waiting on OEM trim. It doesn’t have to.
What wears, and what we keep on the shelf
High-cycle control service is brutal on the internals. The parts that come up every turnaround:
- Trim sets — plugs, seats, cages for throttling and high-pressure-drop service
- Seats & seals — the difference between tight shutoff and a failed leak test
- Packings — including low-emission / fugitive-emission sets
- Positioners — rebuild and replace to bring loops back into spec
Don’t wait 12 weeks. We stock Fisher control-valve rebuild kits, seats, packings, and positioners and ship
them from Houston — so the turnaround stays on schedule.
Modernizing the loop while you’re in there
A turnaround is also the cheapest time to upgrade instrumentation. Siemens SIPART PS2 smart
electropneumatic positioners — HART communication, auto-commissioning, and onboard diagnostics for linear and
rotary control valves — are in stock and shipping from Houston. If you’re already pulling the valve, it’s the
moment to put a diagnostic-capable positioner back on it.
