2" Relief Valve Repair Kit | Complete Rebuild Kit for 15,000 PSI Pop-Off Valve

The 2" Relief Valve Repair Kit provides every essential replacement component required to completely overhaul and restore your 2-inch, 15,000 PSI (15M) pressure relief valve (pop-off valve) to original factory specifications. In high-velocity, high-pressure pumping operations, the internal mechanisms of a relief valve are subjected to immense stress, fluid erosion, and shock loads when actuated. Over time, seats can become worn, and elastomers can degrade. This comprehensive rebuild kit ensures that your critical safety valves remain fully functional, reliably calibrated, and ready to protect your iron and personnel from catastrophic overpressure events.

Designed for direct compatibility with standard 2" Figure 1502 relief valve assemblies, this kit eliminates the need to replace the entire heavy-duty valve body when only the internal wear parts have reached the end of their service life. A standard kit typically includes the primary valve seat, high-strength stem, precision-engineered elastomer seals (such as Viton or Nitrile, depending on service requirements), backup rings, and packing components.

Performing regular, preventative maintenance utilizing this premium repair kit is a highly cost-effective strategy to minimize non-productive time (NPT) in the field. Whether executed in a controlled shop environment or on location between frac stages, rebuilding your pop-off valves with this kit guarantees that the safety fuse of your flowline system will activate flawlessly when a pressure spike occurs.

Features & Benefits

• Complete Overhaul Solution: Includes all necessary internal wear components—seals, seat, stem, and backup rings—to fully refurbish a standard 2" high-pressure relief valve.

• OEM-Level Reliability: Manufactured to exacting dimensional tolerances to ensure seamless fitment, perfect sealing, and accurate pop-off calibration.

• Cost-Effective Maintenance: Allows operators to restore the critical safety functionality of their existing valve bodies without the major expense of purchasing a completely new assembly.

• Extreme Pressure Rated: All metallic and elastomeric components are engineered to withstand the extreme shock and abrasion of 15,000 PSI (15M) blowdown events.

• Field-Ready: Packaged for rapid deployment, allowing maintenance crews to perform quick turnaround rebuilds directly on site or in the repair shop.

Specifications & Technical Details

Applications

This 2" Relief Valve Repair Kit is utilized globally by flowline maintenance shops and field technicians to service pump safety loops, cementing and acidizing lines, and hydraulic fracturing manifolds. It is an essential inventory item for routine recertification programs and emergency field repairs to ensure continuous, safe pumping operations.

Quality Assurance

Every component within this repair kit is subjected to strict quality control to guarantee reliable performance in life-safety applications. Elastomers are batch-tested for durometer hardness and chemical resistance, while metallic components, such as the seat and stem, undergo precise dimensional and surface-finish inspections to ensure bubble-tight reseating after a pressure release event.
