3" FIG 1502 Swing Type Check Valve – Reverse Flow (15K PSI)

The 3" FIG 1502 Swing Type Check Valve (Reverse Flow) is a specialized, high-capacity directional flow control valve engineered for the most rigorous large-bore oilfield applications. Built to safely withstand extreme working pressures up to 15,000 PSI (15K CWP), this integral hammer union check valve ensures unidirectional fluid flow and prevents hazardous backflow during massive pumping, fracturing, and cementing operations.

A key defining feature of this specific high-volume model is its Reverse Flow configuration. Standard check valves typically allow flow in one primary direction relative to the union ends. In this reverse flow model, the massive internal clapper and seat are oriented in the opposite direction. This crucial design allows fluid to flow in reverse, providing essential flexibility for complex manifold rig-ups, specialized high-rate iron layouts, and tight space constraints without the need for additional crossover adapters that could create flow restrictions.

The swing-style mechanism features a large, high-strength disc that swings completely open and out of the primary flow path when active. In a 3-inch flowline, this creates a massive, full-bore unobstructed passage that significantly reduces turbulence and pressure drop. This full-bore design is exceptionally well-suited for high-velocity operations involving highly abrasive fluids, such as heavy cement slurries, massive volumes of frac sand, and proppant-laden flowback.

Features & Benefits

• Reverse Flow Configuration: Internal components are oriented to allow flow opposite to standard check valves, providing critical flexibility for custom large-bore manifold and flowline rig-ups.

• High-Volume, Full-Bore Design: The swing mechanism allows the large 3-inch disc to move completely out of the fluid path, minimizing turbulence and erosion when pumping massive volumes of highly abrasive frac sand and cement.

• Extreme Pressure Rating: The rugged forged steel body is built to safely handle 15,000 PSI cold working pressures in aggressive high-pressure drilling and production environments.

• Integral FIG 1502 Connections: Features standard 3-inch FIG 1502 hammer union ends (Male x Female) for fast, secure, and leak-free makeup and breakout in the field.

• High-Strength Internals: The internal swing disc and seat are machined from heat-treated alloy steel for maximum wear resistance and long-term reliability under highly abrasive conditions.

• Field Maintainable: Designed with a top-entry cover, allowing operators to quickly inspect or replace internal wear components inline without removing the massive valve body from the flowline iron.

Specifications & Technical Details

Applications

The 3" FIG 1502 Swing Type Check Valve (Reverse Flow) is a critical safety asset in high-capacity surface operations where standard flow directions cannot be accommodated. Typical applications include custom large-bore choke and kill manifolds, high-rate fracturing iron setups, heavy cementing lines, aggressive acidizing jobs, and general flowback setups requiring a full-bore flow path and immediate reverse-flow prevention.

Quality Assurance

All our swing type check valves are manufactured from premium forged alloy steel and subjected to rigorous quality control processes. Each unit undergoes strict hydrostatic pressure testing prior to shipment to ensure shell integrity and bubble-tight seal performance under maximum working loads. Full material traceability and certification are available to guarantee safety and compliance with API guidelines.
