In the demanding world of oil & gas, petrochemicals, and district heating systems, reliability isn’t just a feature—it’s a necessity. That’s where Full Welded Valves from Fangyuan Valve Group Co., Ltd. come in. Engineered for maximum integrity and long-term durability, our full-welded valves are the trusted solution for critical applications where leakage is not an option.
Unlike traditional bolted-body valves, Full Welded Valves feature a completely sealed, one-piece body construction. This eliminates potential leak paths at flanged or threaded joints, offering unmatched safety and environmental protection—especially vital in high-pressure or hazardous fluid services. The robust welded design also ensures excellent resistance to external impacts, vibrations, and extreme temperatures, making it ideal for buried installations or harsh industrial environments.
Our Full Welded Valves are manufactured using premium-grade materials and precision welding techniques, fully compliant with international standards such as API 6D, ISO 17292, and ASME B16.34. Each valve undergoes rigorous testing—including shell, seat, and torque tests—to guarantee consistent performance over decades of service with minimal maintenance.
Available in a wide range of sizes (from 2" to 48") and pressure classes (up to Class 900), our valves support various end connections, including butt-weld, socket-weld, and flanged options. Whether you’re managing a pipeline transmission system, an LNG terminal, or a city-wide heating network, our Full Welded Valves deliver zero-emission operation, reduced lifecycle costs, and peace of mind.
At Fangyuan Valve Group Co., Ltd., we don’t just supply valves—we provide engineered solutions backed by technical expertise and global support. Choose Full Welded Valves for uncompromised safety, sustainability, and system efficiency.
