Repair Kit for 2" Dart Type Check Valve

The Repair Kit for the 2" Dart Type Check Valve provides all the essential internal replacement components required to completely rebuild and restore your high-pressure flowline check valve to factory-new operational standards. Designed for use in standard 2-inch dart-style check valves (commonly utilized with FIG 1502 hammer union connections), this comprehensive kit is a critical maintenance asset for ensuring safe, unidirectional fluid flow and preventing dangerous high-pressure backflow during well servicing operations.

High-pressure pumping, fracturing, and cementing operations expose flowline components to extreme abrasion, corrosive fluids, and severe mechanical stress. Over time, the internal dart, seat, and sealing elements of a check valve will wear down. Instead of replacing the entire heavy-duty valve body, this repair kit allows field personnel to quickly swap out the internal wear parts directly on-site, minimizing non-productive time (NPT) and significantly reducing equipment replacement costs.

The kit typically includes a precisely machined high-strength dart, a matched seat, a heavy-duty return spring, and all necessary elastomer seals (O-rings/packings) required to re-establish a bubble-tight, leak-free seal under maximum working pressures up to 15,000 PSI.

Features & Benefits

• Complete Rebuild Solution: Includes all necessary internal components (dart, seat, spring, and seals) to fully restore valve functionality and sealing integrity in one convenient package.

• Field Replaceable: Designed for quick and easy inline maintenance, allowing operators to rebuild the valve on location without sending the unit off-site.

• Cost-Effective Maintenance: Extends the operational lifespan of the expensive check valve body, providing significant cost savings over full valve replacement.

• High-Pressure Reliability: Components are engineered to withstand the extreme shock loads, vibration, and abrasive wear typical of 10K and 15K PSI pumping environments.

• Premium Materials: The metallic components (dart and seat) are machined from heat-treated alloy steel for maximum erosion resistance, paired with high-performance elastomers for reliable sealing.

Specifications & Technical Details

Applications

This repair kit is essential for the routine maintenance and rapid field repair of 2" Dart Type Check Valves used in high-pressure oilfield applications. Typical applications include cementing lines, acidizing jobs, high-rate fracturing manifolds, well testing, and flowback operations where preventing reverse flow is mandatory for equipment and personnel safety.

Quality Assurance

All components within the 2" Dart Check Valve Repair Kit are manufactured to strict OEM-equivalent tolerances and undergo rigorous quality inspections. The metallic parts are precisely machined and heat-treated for optimal hardness and wear resistance, ensuring your rebuilt check valve performs reliably under the harshest oilfield conditions.
