Swing Check Valve, In-Line, 2 in × 206 F×M, 2,000 psi, Standard Service

The Swing Check Valve, In-Line, 2 in × 206 F×M, 2,000 psi, Standard Service is a swing il check valve rated for 2,000 psi working pressure (2K class) with 2 in 206 Female Weco Union inlet and 2 in 206 Male Weco Union outlet. Standard service rated.

In-line swing-disc design — a hinged disc opens with forward flow and swings closed against reverse flow. Low pressure drop (Cv-equivalent close to a full-bore tee), bidirectional installation orientation supported, but horizontal-with-cover-up or vertical-flow-up installation is preferred for cleanest disc seating.

Construction

• Type: Check — Swing — Swing IL
• Nominal size: 2 in
• Bore: Full Port
• Body material: Forged carbon steel (A105N)
• Trim (disc/dart + seat): 316SS disc + 17-4PH stem/hinge
• Seal / elastomer: RPTFE seats + Viton (FKM) O-rings
• Inlet: 2 in 206 Female Weco Union
• Outlet: 2 in 206 Male Weco Union

Performance

Working pressure 2,000 psi. Hydrotested at 1.5× working pressure (shell test); seat-tested per frac-iron flow-control acceptance criteria. Standard service rated for clean hydrocarbon and water-cut streams.

Installation

Install with the flow arrow on the body matching line direction. For swing types, horizontal-with-cover-up is the preferred orientation; vertical-flow-up is also supported. Avoid vertical-flow-down installation (the disc fights gravity to close).

Applications

• Cementing surface lines
• Kill-fluid circulation
• Low-pressure flow-back
• Mud-circulation skid manifolds

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, (c) service class (standard vs sour), (d) installation orientation (especially for dart-type — vertical-flow-up only), and (e) any flow-velocity or noise constraints (over-spec'd swing checks can chatter at low flow). Indus quotes ex-Dubai for stock items and ex-works OEM for build-to-order items, with full mill test reports and pre-shipment hydrotest certificates.

Companion products

Pair with matched-pressure ball valves, plug valves, gate valves, and SSV/ESDs of the same end-connection family. For frac iron service trees, the 1502/602/206 Weco unions are the matched standard. For wellhead and Christmas tree service, the API 6A 5M/10M/15M flanged geometries pair check valves with master and wing gate valves.
