The 2" x 2" Figure 1502 Top Entry Plug Valve Repair Kit for Sour Service is a highly specialized, premium maintenance package engineered to restore full-bore, high-pressure top-entry plug valves deployed in hazardous hydrogen sulfide (H2S) environments. Specifically designed to service 2-inch Top Entry valve bodies—including those configured with standard Figure 1502 Male (Wing) x Female (Thread) ends—this kit ensures your critical isolation barriers remain safely operational. To strictly comply with rigorous safety standards for volatile H2S environments, the components within this kit are engineered to support a secure 10,000 PSI Cold Working Pressure (10M CWP) derated system.
The defining operational advantage of this kit is its compatibility with Top Entry valve architectures. Unlike standard plug valves that must be completely removed from the iron spread for servicing, top-entry valves allow field technicians to remove the bonnet and replace all internal wear components directly on the manifold. This repair kit provides the exact-fit replacement parts needed for a rapid, in-line rebuild, drastically reducing rig downtime and heavy lifting requirements.
Because this kit is designated for Sour Service, every component is heavily upgraded. The elastomeric seals, O-rings, and packing are molded from highly specialized, chemically resistant compounds (such as advanced HNBR or Viton derivatives) formulated to withstand severe H2S degradation and prevent explosive decompression. Any metallic wear components included in the kit undergo stringently controlled heat treatments to strictly comply with NACE MR0175 / ISO 15156 standards, completely neutralizing the threat of Sulfide Stress Cracking (SSC).
(Note: As an internal repair kit, this product contains the replacement seals and internal components designed to fit inside a Top Entry Fig 1502 MxF valve body; the kit itself does not feature external hammer union threads.)
Features & Benefits
-
10,000 PSI Sour Service Rating (10M): Components are specifically engineered and derated to safely contain extreme high-pressure H2S fluid systems up to 10,000 PSI when installed in a certified valve body.
-
Top Entry In-Line Repair: Designed for top-entry valve bodies, allowing field crews to perform complete internal rebuilds while the valve remains connected to the manifold, saving hours of downtime.
-
NACE MR0175 Compliant: All metallic components in the repair kit are manufactured with controlled-hardness alloys to prevent Sulfide Stress Cracking (SSC) in lethal sour gas environments.
-
H2S-Resistant Elastomers: Utilizes premium, chemically resilient seal compounds specifically formulated to resist blistering, degradation, and swelling caused by toxic hydrogen sulfide gas.
-
Full 2-Inch Bore Configuration: Components are scaled to perfectly fit true 2-inch internal bore top-entry valves, ensuring no restriction to maximum flow rates.
-
Comprehensive Rebuild: Provides all necessary consumable seals, backups, and critical wear parts required to restore bubble-tight shutoff and safe manual operation.

Applications
This Top Entry Sour Service repair kit is an absolutely essential maintenance item for operations utilizing top-loading plug valves in H2S environments. It is perfectly suited for on-site, in-line refurbishments of primary master and wing valves on sour fracturing manifolds, rapid preventative maintenance for toxic choke-and-kill assemblies, and restoring compromised isolation valves in large-scale sour well-testing layouts without breaking the iron connections.
Quality Assurance
Each sour service repair kit undergoes the most rigorous quality control protocols in the industry. Elastomeric components are batch-tested for chemical compatibility and rapid gas decompression resistance. All metallic parts undergo strictly documented Hardness Testing to verify NACE MR0175 compliance. Full material traceability (MTRs) is provided to guarantee fail-safe structural integrity in lethal environments.
