API 6A Certified Plug Valves: High-Reliability Fluid Control Solutions for Extreme Conditions
As a flagship product in the oilfield fluid control domain, the AIFUEL plug valve series continuously serves global oil & gas projects. The products strictly comply with the API 6A standard, covering nominal sizes from 1″ to 4″, and are designed for standard, low-temperature, and hydrogen sulfide (H₂S) environments. Multiple core technologies ensure long-term, stable operation. We also offer factory-level repair kits for SPM and FMC branded plug valves, creating a full life-cycle service chain from new valve supply to in-use maintenance.
·Forging Excellence
Valve bodies are made from 42CrMo material, forged using multi-directional die forging technology, achieving industry-leading strength and toughness.
·Core Wear and Corrosion Protection
Plug surfaces are coated with nickel-phosphorus alloy, offering superior wear and corrosion resistance, improved self-lubrication, and fast open/close operations.
·Patented Sealing System
Seal rings use 20CrNiMo material with carbonitriding heat treatment, delivering excellent wear resistance, fatigue resistance, corrosion protection, and significantly extended service life;
Exclusively developed seals with proprietary IP enhance bidirectional sealing performance.
·Flexible Operation Mechanisms
Supports manual, hydraulic, and handwheel drives, suitable for wellheads, manifolds, and all field scenarios.
·Custom Engineering Solutions
Complete engineering adaptation services including:
Ultra-low temperature extension: −46 °C to 121 °C (LU class);
Custom pressure classes, sizes, and connection types;
Optional H₂S-resistant special materials.
·Comprehensive Field Maintenance Support
Factory-level repair kits for SPM/FMC plug valves;
Includes seal rings, plugs, sealing elements, and other core components;
Support for emergency delivery to prevent production losses.
