TEER plug valves

TEER.Founded in the 1980s and headquartered in Lishui, Zhejiang Province, China, TEER is a high-tech enterprise specializing in the research, development, production, and sales of valves. The company occupies a site area of 45,000 square meters, with production and office space totaling 55,000 square meters, and possesses large-scale manufacturing and operational capabilities. The company has established a complete production line covering hot forging, precision casting, welding, heat treatment, machining, assembly, and coating. It is equipped with over 100 sets of advanced processing and testing instruments, including horizontal and vertical CNC machining centers, slant-bed CNC machines, robotic CNC machines, fully automatic gas shielded welding systems, plasma welding systems, and ultra-high-frequency vacuum heat treatment equipment. Concurrently, TEER is establishing a national-level materials testing center and a cryogenic laboratory. It has already equipped these facilities with high-end testing equipment, including universal testing machines, low-temperature impact testers, German portable PMI spectrometers, American portable Brinell hardness testers, magnetic particle and ultrasonic flaw detectors, and helium mass spectrometer leak detectors, and possesses the capability to conduct environmental testing in ultra-low temperatures of -196°C. In terms of certifications and qualifications, TEER has successively obtained ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and OHSAS 18001 Occupational Health and Safety Management System certifications, and has been granted the National Special Equipment Manufacturing License TS-A1, the EU CE Pressure Equipment Directive, the Swedish P-MARK, Russian GOST, American Petroleum Institute (API) certification, API 607 fire-resistance testing, ISO 15848-1 low-leakage testing, and API 591 valve qualification, among other authoritative domestic and international certifications, establishing a comprehensive qualification system. The company’s product range encompasses over 100 categories and thousands of specifications, including gate valves, butterfly valves, globe valves, check valves, ball valves, butterfly valves, wellhead equipment, and Christmas tree assemblies. More than 10 new products independently developed by the company—including the API 6D high-pressure self-sealing double-disc gate valve, internally cladding forged steel ball valve, high-temperature and high-pressure built-in check valve, expansion-type double-seal plug valve, and multi-functional valves for coal chemical industry—have obtained over 20 national patents, demonstrating industry-leading technical capabilities. Thanks to their advantages in key technologies such as low leakage, fire resistance, cryogenic performance, high-temperature and high-pressure resistance, and corrosion resistance, TEER products are widely used in the petroleum, chemical, energy, thermal power, electricity, and marine sectors. They are also extensively exported to numerous countries and regions worldwide, including Malaysia, Indonesia, Singapore, Thailand, Australia, the United Arab Emirates, Saudi Arabia, the United Kingdom, Italy, the Netherlands, the United States, and Canada, where they have earned the trust of customers. The company’s main product lines include ball valves, gate valves, cryogenic valves, plug valves, butterfly valves, pipeline valves, and knife gate valves.
