About US
About Yzng Trong International Co., LTD.
From a CNC machining workshop to a complete valve and actuation manufacturer.
YZNGTRONG (Yzng Trong International Co., LTD.) 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. That same precision background lets us take on demanding custom work — including tailored ball valves for facility piping in the semiconductor and hi-tech industries. With this vertical capability, we support flexible production, custom OEM/ODM development, and the quality our partners rely on.

What We Stand For
Made in Taiwan, Made with Care
Every valve passes through local hands before it reaches yours. We’re proud of where it’s from — and who it’s for.
People First
A valve is only as good as the people behind it. We train them, back them, and keep them — you feel that experience in every part we ship.
Responsible Manufacturing
The greenest valve is the one that lasts. Ours are solid stainless steel — built to stay in the field for years, and fully recyclable when its job is finally done.
