Plug Valve, Lubricated (LT), Gear-Operated, 3 in × 1502 M×F, 15,000 psi, Standard Service

The Plug Valve, Lubricated (LT), Gear-Operated, 3 in × 1502 M×F, 15,000 psi, Standard Service is a lubricated (lt) plug valve rated for 15,000 psi working pressure (15K class), 3 in 1502 Male Weco Union inlet × 3 in 1502 Female Weco Union outlet. Standard service rated.

Lubricated taper-plug design — body sealant is injected through ports in the bonnet to seal between the tapered plug and body cavities. Periodic re-injection (typically each frac stage or test cycle) maintains the bubble-tight seal. Field-serviceable: the sealant-injection ports are accessible without removing the valve from the line.

Construction

• Type: Plug — Lubricated (LT)
• Operation: Gear-Operated
• Nominal size: 3 in
• Body material: Forged AISI 4130
• Trim (plug + seats): 17-4PH plug + 410SS body inserts (sealant-injected)
• Seal / liner: RPTFE back-up + Viton (FKM) primary seals
• Inlet: 3 in 1502 Male Weco Union
• Outlet: 3 in 1502 Female Weco Union

Performance

Working pressure 15,000 psi. Quarter-turn open / closed operation — full open in 90° of stem rotation, with bubble-tight shut-off in both flow directions. Standard service rated. Gear-operated handwheel — the gear ratio reduces operating torque on larger sizes (3-inch and up) and at higher pressure classes (15K+). Position indicator on the gear housing confirms open / closed state.

Applications

• 3-inch high-rate frac discharge
• Cement-unit pump-off lines
• 15K service trees (3-inch leg)
• High-pressure pumping iron — sweet wells

Compliance

• Manufactured to recognised oilfield flow-iron design standards
• 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 LT plug valves, also stock the matching sealant grease for periodic re-injection (specify per OEM recommendation). For frac iron, the 1502/602/206 Weco union family is the matched standard.
