Company profile
Transworld Steel Enterprise Co., Ltd. was established in 1992 and has devoted more than 30 years to the design and manufacture of high-quality ball valves, with products supplied to more than 30 countries for pharmaceutical, food and beverage, pulp and paper, chemical, oil and natural-gas, and electricity industries. In 1999, the founder introduced the direct mounting ball valve and obtained patents for the design in the USA, Germany, and China, strengthening the company's presence in international markets. The company continues to invest in valve innovation and maintains a portfolio of patented technologies while developing additional products through its R&D capabilities. In response to market demand, Transworld Steel established an investment-casting foundry in Vietnam in 2008 and connected upstream and downstream processes to support manufacturing efficiency, quality control, and adaptability to market changes. The company invested in Industry 4.0 and IIoT initiatives including robotic arms and intelligent visual monitors, and its second factory, established in 2010, includes an automated machining line. Its infrastructure also includes an advanced valve laboratory with a broad range of testing equipment and a certified clean room with classifications of 10,000 and 100 for vacuum packing. Transworld Steel holds ISO9001, API 6D, PED 2014/68/EU Module H, EN10204-3.1, SIL, API 607, ISO 15848, TA-Luft, ISO 10497, ATEX, REACH, and ROHS certifications and compliance credentials, and it integrates solar panels together with ISO 14001 and ISO 14064-1 certifications. The company has received the Rising Star Award from the Ministry of Economic Affairs and the Model of Entrepreneurs recognition from the National Innovation and Entrepreneurship Association. Annual output is 360,000, with Made in TAIWAN 100% and Green Energy 40% among the company's operating figures.

Transworld Steel applies its R&D design experience to specific customer requirements and develops valve products around demanding operating needs, with R&D, laboratory testing, clean-room production, precision inspection, CNC machining, and automation forming part of its production capability. Its precision valve laboratory performs pressure testing to API 598 / EN 12266-1, fire-safe testing to API 607 / ISO 10497, fugitive-emission testing to TA Luft / ISO 15848, torque testing under ambient, pressurized, and elevated-temperature conditions, and cycle testing for stem endurance, seat durability, and lifecycle performance under high temperature and pressure. Temperature-test capability covers +500℃, -50℃, and -196℃; the laboratory also provides high-temperature vacuum testing at 500℃ with vacuum 3x10-3torr and 1500psi maximum pressure using nitrogen, a -60℃ cryogenic freezer with 2900 psi maximum pressure using nitrogen, and ultra-low-temperature testing with liquid nitrogen at -196℃ and 2000 psi maximum pressure using helium. The laboratory also includes a PTFE Seat Life Testing Unit specified for ambient temperature, with pressure and medium marked N/A. For sanitary products, clean-room controls are used to reduce airborne particle contamination, support cleaning and maintenance of pharmaceutical equipment, improve dust control, and manage risks of cross-contamination involving steroids, cytotoxins, or hormones by controlling particles and biological microorganisms in the manufacturing environment. The clean-room production scope includes Sanitary Ball Valve, Pharmaceutical Ball Valve, Oxygen Service Valve, and Gas Valve products, supported by Clean Dry Air and Ultrapure Water systems and clean-room specifications including PIC/S GMP = EU GMP Systematics Standard, FED-STD-209E Class 100 / Class 10K, and ISO 14644-1 Class ISO 5 to Class ISO 7. Electropolishing is used to remove surface contaminants from castings, improve light reflection and shine, and increase corrosion resistance, providing a surface-treatment option for sanitary-valve production. Sanitary-valve inspection uses calipers, torque wrenches, 3D measurement devices, pressure-testing equipment, surface-roughness gauges, and ferrite-content detectors, and finished sanitary valves are additionally wrapped in plastic bags and sealed inside standard cartons to protect them from contamination during transport. Manufacturing uses high-capacity CNC machines together with precision automated measurement systems, automation systems, and robotic programming to increase production efficiency, reduce machine-adjustment time and labor costs, and save capital expenditure. The machining operation also integrates Universal Robots™ with CNC lathes; technicians completed initial modular programming in 4 hours and had a UR collaborative robot fully operational within 7 hours, providing rapid setup, minimal training requirements, and high safety. The IoT-integrated machining environment has a Smart Monitoring Rate of 85%, more than 35 CNC machines, and more than 7 robotic arms. For high-purity and semiconductor applications, Transworld Steel offers High-Purity / Semiconductor Ball Valve series S600-70, S701-70, S900-70, S604-20 (Sanitary), S704-20 (Sanitary), and S904-20 (Sanitary), with size ranges of 1/4" to 4" for S600-70, S701-70, and S900-70 and 1/2" to 4" for the sanitary versions. These high-purity and semiconductor ball valves list pressure options of 800, 1000, 1500, and 2000 psi; body materials CF8, CFBM, CF3, and CF3M with 304 / 304U 316 / 316L references and other alloys available on request; and a temperature range of -20°C to 180 °c (-4°F to 356°F). Connection options include SCH SS auto butt-weld, SCH 10 manual butt-weld, Tube OD, Pipe ID, and Pipe; the tightness class is Helium 2.67X10^-5 mbar*I/(s*mm), purge-port availability is NPP, OPP, and IOPP, and casting specifications conform to MSS-SP-55. Internal-surface options are AP Ra ≤ 1.0 µm, MP Ra ≤ 0.5µm Mechanical Polishing, and EP Ra ≤ 0.2µm Electropolishing, with lever and actuator handle types and an anti-static-device option.
