Plug Valve, Non-lubricated (TE), Manual, 3 in × 206 M×F, 2,000 psi, Sour Service

The Plug Valve, Non-lubricated (TE), Manual, 3 in × 206 M×F, 2,000 psi, Sour Service is a non-lubricated (te) plug valve rated for 2,000 psi working pressure (2K class), 3 in 206 Male Weco Union inlet × 3 in 206 Female Weco Union outlet. NACE MR0175 / ISO 15156 sour-service compliant.

Non-lubricated taper-plug design — a PEEK / elastomeric liner seats against the tapered plug to deliver bubble-tight shut-off without sealant injection. No periodic maintenance required during operation. Trade-off: liner replacement at each major service interval; lower max temperature than the LT variant.

Construction

• Type: Plug — Non-lubricated (TE)
• Operation: Manual
• Nominal size: 3 in
• Body material: Forged carbon steel (LF2) — NACE MR0175 compliant
• Trim (plug + seats): 17-4PH plug + PEEK liner
• Seal / liner: PEEK back-up + HNBR primary seals
• Inlet: 3 in 206 Male Weco Union
• Outlet: 3 in 206 Female Weco Union

Performance

Working pressure 2,000 psi. Quarter-turn open / closed operation — full open in 90° of stem rotation, with bubble-tight shut-off in both flow directions. NACE MR0175 sour-service compliant — material class EE. Manual quarter-turn handle — direct lever or wrench-operated. Position is visually indicated by the handle alignment (in-line = open, perpendicular = closed). Suitable for sizes ≤ 2-inch and pressure classes up to 15K.

Applications

• 3-inch sour cementing iron
• Low-pressure mud-circulation manifolds
• Bulk-flow kill / circulation lines
• Tank-farm cross-over manifolds

Compliance

• Manufactured to recognised oilfield flow-iron design standards
• Material class EE (API 6A chemistry / sour-service grading)
• NACE MR0175 / ISO 15156 (sour-service)
• Mill test reports per EN 10204 3.1 / 3.2

How to order

Confirm (a) line working pressure and pressure class, (b) inlet and outlet end-connection sizes / styles (specify reducing variants like 2"×1" if needed), (c) service class (standard vs sour), (d) operation preference (manual lever vs gear-operated handwheel), (e) for LT variants, sealant brand / chemistry preference. Indus quotes ex-Dubai for stock items and ex-works OEM for build-to-order, with full mill test reports and pre-shipment hydrostatic test certificates.

Companion products

Pair with matched-pressure ball valves, gate valves, check valves, and chokes of the same end-connection family. For non-lubricated TE plug valves, also stock the matching liner / o-ring kit for service-interval replacement. For frac iron, the 1502/602/206 Weco union family is the matched standard.
