The 2" x 2" Figure 1502 Low Torque (LT) Plug Valve for Sour Service is a heavy-duty, high-capacity flow control component engineered for the safe, reliable management of full-volume, high-velocity fluids in hazardous, hydrogen sulfide (H2S) rich upstream environments. Featuring a true 2-inch straight-through bore, this valve is designed to handle maximum pump rates while significantly minimizing fluid turbulence and pressure drop. To strictly comply with critical safety standards for volatile H2S environments, this Figure 1502 component is explicitly derated to a highly secure 10,000 PSI Cold Working Pressure (10M CWP), providing a fail-safe isolation barrier during toxic flowback, well testing, and sour stimulation operations.

What strictly defines this full-bore plug valve is its NACE MR0175 / ISO 15156 compliant metallurgy. The premium forged alloy steel undergoes a rigorously controlled heat treatment process to limit material hardness, completely neutralizing the threat of Sulfide Stress Cracking (SSC) and hydrogen embrittlement common in lethal sour gas applications. The internal sealing components are also heavily upgraded, utilizing specialized, H2S-resistant elastomeric compounds formulated to withstand aggressive chemical degradation.

Working in tandem with this rugged metallurgy is the highly efficient Low Torque (LT) internal architecture. Operating under extreme 10,000 PSI differential pressure can cause standard high-volume valves to lock or bind. The LT design utilizes specialized high-strength bearings and floating seal segments to significantly reduce friction against the precision-ground cylindrical plug. This ensures that field operators can easily and smoothly open or close the primary flowline manually—even under maximum pressure—allowing for rapid, safe responses without requiring excessive physical exertion.

Configured with standard Figure 1502 Male (Wing Nut) x Female (Thread) ends, this 2" x 2" sour service valve integrates seamlessly into high-pressure H2S frac spreads, well-testing layouts, and choke manifolds, delivering dependable, large-volume fluid isolation.

Features & Benefits

  • 10,000 PSI Sour Service Rating (10M): Specifically engineered and derated to safely manage extreme high-pressure H2S fluid systems with a 10,000 PSI Cold Working Pressure rating.

  • NACE MR0175 Compliant: Manufactured with specially heat-treated, controlled-hardness alloy steel to prevent Sulfide Stress Cracking (SSC) in lethal sour gas environments.

  • Full 2-Inch Bore: Accommodates high flow rates and abrasive slurries while drastically minimizing flow turbulence and internal fluid erosion.

  • Low Torque (LT) Design: Advanced internal bearing and floating seal architecture radically reduces friction, ensuring smooth, non-stick manual operation under full load.

  • H2S-Resistant Sealing: Utilizes precision-machined metal-to-metal seats combined with resilient lip-type seals formulated specifically for sour gas chemical compatibility.

  • Male x Female Connections: Features standard Fig 1502 hammer union ends for fast, highly secure integration into existing sour service flowline networks.

Applications

This full-bore, high-pressure sour service LT plug valve is an absolutely critical safety asset for operations where hydrogen sulfide (H2S) is present. It is ideally utilized as a primary master or wing valve on sour fracturing manifolds, a dependable isolation barrier on severe-service H2S flowback spreads, an active control valve within sour well-testing layouts, and any hazardous application requiring maximum 2-inch fluid flow combined with effortless manual operation.

Quality Assurance

Each sour service plug valve undergoes the most rigorous quality control protocols in the industry. This includes severe hydrostatic pressure testing of the body and seat under full load, torque testing to verify LT capabilities, magnetic particle inspection (MPI), and strictly documented Hardness Testing to verify NACE MR0175 compliance. Full material traceability (MTRs) is provided to guarantee fail-safe structural integrity.
