From a CNC machining workshop to a complete valve and actuation manufacturer.

Yzng Trong began as a precision CNC machining workshop, producing parts to exacting tolerances for other manufacturers. That machining foundation became our advantage: in 1999 we formally established Yzng Trong International Co., LTD. and turned our precision know-how toward our own products — stainless steel ball valves.

Over the years we developed a full range of ball valves in-house, from one-piece and two-piece designs to integral one-body construction, each refined for tight sealing, durability, and consistent quality. As our customers’ systems grew more automated, we extended beyond manual valves into actuation, developing pneumatic and electric actuators so we can supply complete, ready-to-install valve assemblies.

Today, Yzng Trong is a professional valve and hardware manufacturer based in Taiwan, combining precision machining, in-house valve development, and actuator integration under one roof. With this vertical capability, we support flexible production, custom OEM/ODM development, and the quality our partners rely on.

We don’t just supply products — we provide solutions that drive your competitive edge.
