TIANCHENG VALVE.TIANCHENG VALVE was established on July 20, 2001. The company occupies over 200 acres of land with a paid-in capital of 56 million yuan, demonstrating robust financial strength. It specializes in the research, development, production, and sales of high- and medium-pressure valves. TIANCHENG VALVE remains steadfastly committed to technological innovation, focusing on the development of high and medium pressure valve series. Leveraging its advantages in R&D, including highly qualified personnel and a modern valve testing center, the company continuously innovates and advances, having obtained over 100 national invention patents and utility model patents. The company strictly adheres to advanced domestic and international standards including GB, JB, API, ANSI, JIS, BS, and DIN. It has obtained certifications such as the People's Republic of China Import and Export Enterprise Qualification Certificate, American Petroleum Institute API 6D Certification, Quality Management System Certification, Environmental Management System Certification, Occupational Health and Safety Management System Certification, and the National Special Equipment Manufacturing License (TS A1, B Grade). We develop and manufacture ball valves, gate valves, globe valves, butterfly valves, check valves, control valves, piston valves, electric valves, solenoid valves, power plant valves, and blowdown valves. We also provide instrument valves, petroleum accessory valves, pipeline fittings, municipal facilities, and industrial automation control systems tailored to customer requirements. Valve body materials include WCB, A105, WC6, WC9, CF8, CF8M, CF3, CF3M, alloy materials, and corrosion-resistant fluorine-lined materials. Drive types encompass manual, gear-driven, electric, pneumatic, and hydraulic operation. Pressure ratings range from 0.6 MPa to 42 MPa, with operating temperatures spanning -196°C to 800°C and nominal diameters from DN6 to DN6000 mm. Valve components are precision-machined using CNC lathes and other advanced equipment to ensure dimensional accuracy and interchangeability. Sealing surfaces employ advanced automatic surfacing technology and processes, while valve seats utilize split threaded seat and split insert welded seat designs. Our products are widely applied in power plants (thermal and hydroelectric), refining, chemical, fertilizer, metallurgical, mining, natural gas, papermaking, pharmaceutical, and municipal engineering industries. They are exported to the United States, Japan, Europe, Southeast Asia, and other regions. Primary product lines include: gate valves, globe valves, butterfly valves, ball valves, check valves, plug valves, metallurgical valves, pressure reducing valves, control valves, steam traps, discharge valves, filter valves, solenoid valves, expansion joints, compensators, pipeline accessories, and high-pressure valves.
