Dart Check Valve, Compact, 2 in × 1502 F×M, 15,000 psi, Standard Service

The Dart Check Valve, Compact, 2 in × 1502 F×M, 15,000 psi, Standard Service is a dart compact check valve rated for 15,000 psi working pressure (15K class) with 2 in 1502 Female Weco Union inlet and 2 in 1502 Male Weco Union outlet. Standard service rated.

Compact-body vertical-flow dart-style design — same operating principle as the standard dart but in a shorter overall length. Used where space between unions is tight, e.g. tightly-packaged frac iron service trees and frac trees.

Construction

• Type: Check — Dart — Dart Compact
• Nominal size: 2 in
• Bore: Full Port
• Body material: Forged AISI 4130
• Trim (disc/dart + seat): F6NM dart + 316SS body insert
• Seal / elastomer: RPTFE seats + Viton (FKM) O-rings
• Inlet: 2 in 1502 Female Weco Union
• Outlet: 2 in 1502 Male Weco Union

Performance

Working pressure 15,000 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 vertical-flow-up only — the dart relies on gravity returning to seat. The body must be plumbed so the dart axis is vertical and the inlet is below the outlet.

Applications

• Tight-package service trees
• Skid-mounted frac iron
• Wireline / coiled-tubing pressure-control stack
• High-rate 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, (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.
