"C" Flat Valve
API 6A "C" Flat Gate Valves deliver superior wellhead isolation with 20,000 PSI pressure rating and fire-safe metal-to-metal seals (API 607 certified). The compact C-profile design reduces installation footprint by 30% versus standard valves, while PSL3G/PR2 certification ensures reliability in sour service (NACE MR0175 compliant). Featuring pressure-energized stem seals and carbide-coated gate surfaces, these valves provide zero-leak performance in both high-temperature (350°F) and cryogenic (-75°F) conditions.
Product Details
Ultra-Durable WEFICC Flat Gate Valves for Extreme Service Conditions
(API 6A PSL3G/PR1 Certified | 15K PSI Rated | Carbide-Sprayed Seals)
Product Overview
Our WEFICC flat gate valves (11-3/16" to 7-1/16") are engineered for critical isolation in oil & gas wellheads and pipeline systems. Featuring cemented carbide-sprayed metal seals, these valves withstand abrasive/corrosive media while maintaining bubble-tight sealing from -75°F to 350°F. The inverted stem seal design allows live maintenance without system shutdown.
Key Features & Benefits
1. Robust Construction for Harsh Environments
- Pressure Range: 2,000–15,000 PSI with K-X temperature rating (API 6A compliant).
- Wear Resistance: Tungsten carbide-coated sealing surfaces extend service life by 3x in sand-laden flows.
- Material Grades: AA-HH alloys (including NACE MR0175 options for sour service).
2. Maintenance-Optimized Design
- Inverted Stem Seal Structure: Enables seal replacement under full pressure (API 6A Annex F compliant).
- Low-Friction Operation: Optimized stem geometry reduces actuation torque by 25%.
3. Compliance & Customization
- Certifications: API 6A PSL1-PSL3G, PR1 Performance Level.
- Actuator Options: Manual handwheel, pneumatic actuator, or hydraulic fail-safe configurations.
