Key Product Highlights
1. Industry-Leading Sealing Performance for Natural Gas Safety
The valve features a precision-lapped F316 stainless steel ball paired with high-performance PEEK seat seals, delivering bi-directional bubble-tight shutoff that exceeds API 6D and API 607 fire-safe requirements. PEEK’s exceptional chemical resistance to natural gas and hydrocarbons, combined with its high mechanical strength and thermal stability, ensures long-term sealing integrity, eliminating fugitive emissions and meeting global environmental compliance standards for natural gas pipelines. This zero-leakage design is critical for preventing gas loss, reducing safety risks, and optimizing system efficiency in fuel gas supply networks.
2. Extreme Pressure & Temperature Resistance
Engineered for ASME Class 600LB service, the A105 forged carbon steel body withstands a maximum operating pressure of 43 bar.g and design pressure of 50 bar.g, while supporting operating temperatures up to 220°C and design temperatures up to 340°C. This robust construction ensures reliable performance in high-pressure natural gas transmission lines, compressor stations, and industrial fuel gas systems, even in extreme operating environments. The A105 material’s superior tensile strength and impact resistance make it ideal for heavy-duty pipeline applications, outperforming cast steel alternatives in durability and fatigue resistance.
3. Premium Material Selection for Long Service Life
• A105 Forged Carbon Steel Body: Offers enhanced structural integrity, corrosion resistance, and impact toughness compared to cast valves, ensuring decades of reliable service in natural gas infrastructure.
• F316 Stainless Steel Ball: Provides excellent corrosion, erosion, and pitting resistance, preventing wear from natural gas flow and ensuring smooth, consistent operation over the valve’s lifecycle.
• PEEK Seat Material: Delivers outstanding thermal stability, chemical inertness, and wear resistance, outperforming traditional PTFE seats in high-temperature natural gas applications and maintaining sealing performance across the full operating temperature range.
4. Reliable Lever Operation & Easy Maintenance
The manual lever actuation design enables quick, visual position indication and smooth 90° on/off operation, allowing for fast emergency shutoff and precise flow control. The valve’s modular, bolted body construction and accessible internal components simplify routine inspection and maintenance, reducing downtime and operational costs for pipeline operators. The lever design also ensures fail-safe manual operation, eliminating reliance on external power sources for critical shutoff functions.
5. Full Compliance with International Industry Standards
All design, manufacturing, testing, and inspection processes strictly adhere to API 6D, ASME B16.34, ANSI B16.5, and API 607 (fire-safe) standards, ensuring full compatibility with global natural gas pipeline projects. This compliance guarantees the valve meets the requirements of international oil and gas EPC contractors, pipeline operators, and regulatory bodies, simplifying project approval and installation.
