2" FIG 1502 Flapper Type Check Valve – Reverse Flow (15K PSI)

The 2" FIG 1502 Flapper Type Check Valve (Reverse Flow) is a specialized, heavy-duty directional flow control valve engineered for the most rigorous high-pressure 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 demanding pumping, fracturing, and cementing operations.

A key defining feature of this specific model is its Reverse Flow configuration. Standard check valves typically allow flow in one primary direction relative to the union ends (usually male to female). In this reverse flow model, the internal flapper 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 iron layouts, and tight space constraints without requiring extra crossover adapters.

Furthermore, the flapper mechanism features a hinged clapper that swings completely open and out of the primary flow path when active. This creates a full-bore, unobstructed passage that significantly reduces turbulence, making it exceptionally well-suited for high-velocity operations involving highly abrasive fluids like heavy cement slurries, 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 manifold and flowline rig-ups.

• Full-Bore Flow Design: The flapper mechanism moves completely out of the fluid path, minimizing turbulence and erosion when pumping highly abrasive frac sand and cement slurries.

• Extreme Pressure Rating: 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 2-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 flapper and seat are machined from heat-treated alloy steel for maximum wear resistance and long-term reliability under abrasive conditions.

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

Specifications & Technical Details

Applications

The 2" FIG 1502 Flapper Type Check Valve (Reverse Flow) is a critical asset in high-pressure surface operations where standard flow directions cannot be accommodated and large volumes of abrasive fluids are pumped. Typical applications include custom choke and kill manifolds, high-rate fracturing iron setups, cementing lines, acidizing jobs, and general flowback setups requiring a full-bore flow path and immediate reverse-flow prevention.

Quality Assurance

All our flapper 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.
