Shanghai Valve No. 5 Co., Ltd., located in Jiading District, Shanghai, is a Shanghai High-Tech Enterprise under the Shanghai Electric Group, with nearly 70 years of professional valve R&D and manufacturing history. The company is currently undergoing a transformation from traditional manufacturing to a dual-driven model centered on “high-end valves + intelligent services,” possessing a registered capital of RMB 120 million and an A-grade tax credit rating for 2023. Its core business covers sectors including petroleum, chemical, power, metallurgy, municipal engineering, and nuclear power supporting systems, with key service areas encompassing petrochemical refining (e.g., ebullated-bed residue hydroprocessing units), coal chemical processing, fine chemical production, critical nuclear power systems, and overseas energy projects under the Belt and Road Initiative. Core capabilities include complete design and manufacturing of specialty valves for extreme operating conditions—such as ultra-high temperature (≥650°C), ultra-low temperature (≤−196°C), hydrogen sulfide (H₂S) resistance, and high sealing performance (ISO 5208 Class A/B). The company possesses ANSYS Fluent flow-field simulation capability, SolidWorks Simulation structural strength analysis capability, and full FAT (Factory Acceptance Test) capability certified by DNV GL. Its independently developed “Intelligent Valve Monitoring System (IVMS-2000)” has been deployed across multiple key enterprises in the Shanghai Chemical Industry Park and supports integration into DCS platforms via Modbus TCP/OPC UA protocols. The company holds ISO 9001/14001/45001 integrated management system certifications; Special Equipment Production License TS grades A1 (ultra-high pressure), A2 (high pressure), and B (medium/low pressure); and type-test and factory inspection capabilities conforming to mainstream standards including API 598, API 6D, GB/T 12234, and GB/T 12237. It has also completed the EU PED 2014/68/EU Declaration of Conformity and obtained CE marking authorization. Representative projects include: supply of Nuclear Class II globe valves and isolation valves for Unit 2 of Sanmen Nuclear Power Plant in Zhejiang Province (successfully passed on-site supervision and acceptance by China National Nuclear Safety Administration in 2023); supply of H₂S-resistant fully welded ball valves for the ebullated-bed residue hydroprocessing unit at Sinopec Zhenhai Refining & Chemical Company (operating fault-free for three consecutive years as of 2024); and phased delivery of API 6D pipeline ball valves for the modernization retrofit project of the Atirau Refinery in Kazakhstan (deliveries conducted in three batches between 2022 and 2025). Products have been exported to 21 countries, including Russia, India, Vietnam, the United Arab Emirates, and Argentina, with support for ASTM material retesting, hydrostatic burst testing, and pre-audit for ASME BPVC Section III Division 1 NPT certification. The company offers technical licensing, consortium-based EPC collaboration, localized delivery, and full-lifecycle operation and maintenance services.
