This DBB ball valve addresses the need for seamless integration in mixed-diameter pipeline systems. The 3x2-inch flanged design simplifies connections between 3-inch and 2-inch pipelines, reducing installation complexity and leak points. F316 stainless steel construction provides exceptional resistance to chloride-induced corrosion, while the DBB mechanism offers dual redundant sealing and a bleed port for safe pressure release. Fire-safe and anti-static features protect against explosions in flammable environments, while full-bore variants enable unobstructed flow for pipeline pigging. With a compact footprint and low-torque operation, it enhances system efficiency in oil & gas, petrochemical, and water treatment sectors, delivering long-term durability with minimal maintenance.

Space-Saving Reduced-Bore Design
The 3x2-inch reduced-bore configuration eliminates the need for separate reducers, reducing installation time by 40% and system complexity in tight spaces. This design is critical for retrofitting existing pipelines or connecting equipment with mismatched diameters, such as pumps, heat exchangers, and storage tanks. By consolidating components, it minimizes potential leak points, aligning with ASME B31.3 process piping standards and reducing maintenance costs in chemical plants and refineries.
Fire-Safe & Anti-Static Compliance
Compliant with API 607 and ISO 10497, the valve’s fire-safe design uses graphite-filled PTFE seals and metal backup rings to maintain integrity during fires, preventing catastrophic releases of hydrocarbons or toxic gases. Its anti-static mechanism—conductive springs between the stem, ball, and body—dissipates electrostatic charges, reducing ignition risks in LNG terminals and fuel storage facilities. These features are essential for meeting ATEX directives in explosive atmospheres, ensuring worker safety and regulatory compliance.
Corrosion Resistance in Harsh Media
F316 stainless steel, containing 2-3% molybdenum, resists pitting and crevice corrosion in chloride-rich environments like seawater and acidic chemicals. This makes it suitable for offshore platforms, pharmaceutical reactors, and wastewater treatment plants where standard 304 stainless steel fails prematurely. Its passive oxide layer withstands prolonged exposure to sulfuric acid (pH 1-2) and sodium hydroxide (pH 12-14), ensuring a service life exceeding 15 years in corrosive conditions.
Bi-Directional Flow & Pressure Control
The valve’s floating-ball design supports bi-directional flow, allowing flexible integration into complex piping networks without flow restrictions. This is critical for applications requiring frequent system reversals, such as batch chemical reactors and water recycling systems. With a pressure rating of 600LB, it maintains tight shutoff in high-pressure steam lines and gas transmission systems, ensuring reliable operation in power plants and oil refineries.
Low Maintenance & Longevity
The self-lubricating PTFE seats and grease-injected stem packing reduce friction, extending service intervals to 5+ years in normal conditions. Its modular design enables field replacement of seals and bearings without removing the valve from the pipeline, cutting downtime by 70% compared to traditional gate valves. This reliability is proven in continuous-operation environments like LNG terminals and chemical batch reactors, where unscheduled maintenance can lead to production losses exceeding $1 million per hour.
Global Compliance & Versatility
Certified to API 6D, ISO 15848-1, and CE, the valve meets international standards for fugitive emissions and safety. It accommodates temperatures from -29°C to 204°C and is compatible with diverse media, including hydrocarbons, steam, and aggressive solvents. Its flanged connections comply with ASME B16.5 and EN 1092-1, ensuring seamless integration into global projects, while optional actuation (pneumatic, electric) supports automation in smart factories and remote operations.
