3” ESV valve (ESV product family) · ESV
Obsolete
No longer orderable new (last-time-buy ended Feb 2011).
Ask Drake about repair / overhaul of your existing unit.
Drake-recommended replacement candidates
Replaced by a combination of items.
| Preferred item | Description | Applies when |
|---|---|---|
| 3” HR LESV | 3” High Recovery LESV | Major outline dimension changes (source does not list all dimensions): flange-to-pipe-centerline at valve inlet and discharge increases by .750 inches nominally; overall height increases by ~10.0 inches; 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 |
| 3” SR LESV | 3” Standard Recovery LESV | Flange-to-pipe-centerline at valve inlet and discharge is nominally the same; overall height increases by ~8.0 inches (source page 6); 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 |
Note: No orderable part numbers are printed for the obsolete ESV or the replacement LESV models — replacements are model/size designations only; Drake confirms the exact replacement before quoting. Status and dates come from the family-wide Product Support Statement on page 2 (February 2010 support letter; after February 2011 repair/overhaul only as parts are available; no further sales of full assemblies; special support consideration for existing sites provided to GE). Evidence quote covers the 3” HR LESV conversion on page 3; the 3” SR LESV conversion is printed on page 6 of the same document. High Recovery vs Standard Recovery selection is application-dependent. rtype=combination because the conversion also requires the DVP valve driver and connector/wiring changes, not the valve alone. Support letter published: 2010-02.
