Designed for Maximum Reliability and Zero Fugitive Emissions

Our forged steel fully welded ball valves represent the pinnacle of valve engineering technology, featuring a fully welded body structure that eliminates all external flanges and bolted connections. This innovative design ensures zero external leakage, making it ideal for high-pressure, high-temperature, and hazardous media applications where safety and reliability are paramount. The valve is manufactured from high-strength forged steel materials and undergoes rigorous quality control processes, including ultrasonic testing and liquid penetrant testing, to ensure structural integrity and long-term performance.

Engineered with Advanced Fully Welded Technology

The core of our forged steel fully welded ball valve lies in its integral welded valve body structure. Unlike traditional ball valves that rely on bolted flanges and gaskets for connection, this ball valve features a seamless welded design, eliminating the most common source of leaks. The trunnion-mounted ball is supported by precision bearings, which absorb the thrust generated by pipeline pressure, significantly reducing operating torque even at rated pressure. The valve utilizes spring-loaded seats and offers carbon fiber reinforced PTFE or metal sealing options, providing bidirectional sealing and bubble-tight shutoff performance.

Delivering Unmatched Performance Across Extreme Conditions

Our forged steel fully welded ball valves demonstrate exceptional performance under a wide range of operating parameters. This series of valves is available in sizes ranging from 2 inch to 60 inches (DN50 to DN1500) and pressure ratings from Class 150 to Class 2500 LB (PN20 to PN420).  The operating temperature range is from -46°C to 121°C, making them suitable for both cryogenic and high-temperature applications. The valve bodies are constructed from A105 forged carbon steel, stainless steel (F304/F316), duplex stainless steel, or special alloy materials, and are available in full bore or reduced bore configurations to meet specific flow requirements.

Built for Critical Industrial Applications

Forged steel fully welded ball valves are indispensable critical components in industries where zero leakage and maximum reliability are paramount. They are widely used in oil and gas pipelines, natural gas distribution networks, petrochemical processing plants, and power generation facilities. These valves are particularly suitable for applications such as main pipeline isolation, compressor stations, metering stations, and offshore platforms, where leaks could have catastrophic consequences. Their fire-safe design, compliant with API 607 standards, ensures continued operation even in emergency fire situations.

Manufactured to Rigorous International Standards

Our forged steel fully welded ball valves are manufactured strictly in accordance with API 6D, ASME B16.34, ISO 17292, and BS EN ISO 14313 standards. Each valve undergoes comprehensive testing to meet API and ISO standards, including hydrostatic shell testing and bidirectional seat testing at 1.5 times the maximum working pressure. The products feature an anti-static design and a blow-out proof stem structure.provide additional safety layers, while the double block and bleed (DBB) configuration ensures reliable isolation in high-risk scenarios.
