Drake-recommended replacement
Drake confirms the correct replacement.
| Preferred item | Description | Applies when |
|---|---|---|
| LESV | LESV valve product family — High Recovery (HR) and Standard Recovery (SR) versions, 2” and 3” sizes | Conversion requires the Woodward DVP (Digital Valve Positioner) — the EM Digital Driver will not operate the LESV; MS-style connectors require mating connectors or Woodward-supplied wire harnesses; outline dimensions change vs the ESV (HR: overall height increases ~10.0 inches; SR: overall height increases ~8.0 inches) |
Note: Family-level supersession only: no old-PN -> new-PN table and no orderable part numbers are printed anywhere in this 8-page presentation, so the replacement is identified by family/model designation only — Drake confirms the exact replacement configuration before quoting. Verbatim status language: after February 2011 the product 'would only be repaired or overhauled as parts are available' and 'No further sales of full assemblies are available'; both bullets carry the footnote 'Special support consideration for existing sites have been provided to GE'. LESV comes in High Recovery and Standard Recovery versions (per-size records carry the printed dimensional differences). The EM Digital Driver is not itself declared obsolete by this document; it only states the EM Digital Driver will not operate the LESV (DVP required). Support letter published: 2010-02.
