Established in July 2003, Tzyy Jenq Industry Ltd. focuses on R&D and manufacture of industrial and food-grade stainless steel ball valves that are highly regarded by customers at home and abroad. An experienced maker and exporter, we supply high-quality products with complete after-sales service.

Our products are designed for dairy, food processing, pharmaceutical, beverage making, biotechnological, chemical engineering, petroleum, marine hardware, semiconductor processing, and water purifying applications.

Our industrial and food-grade stainless steel ball valves are available in one-, two-, and three-piece models (threaded, socket welded, short/long butt welded, flanged, food-grade butt welded, food-grade with T-clamp), mainly of WCB 304/316/316 L that are rustproof and anti-corrosive, and are lost-wax cast for blanks, processed, and assembled in-house. Custom orders of any kind are welcome.

We also make auto/motorcycle, hydraulic, pneumatic parts, eco-friendly chopsticks, and mechanical parts & components using CNC milling, lathing, and multi-tasking machines. Contact us for more information.
