high performance ball valveThe Z2 split-body metal-sealed ball valve is a fully customizable valve suitable for special operating conditions such as high temperature, high pressure, and wear resistance. It can be used in harsh operating conditions, including but not limited to chemical/petrochemical, refineries, power plants, and mining.

In 1982, Union Tech, located in Houston, Texas, USA, entered the precision machining industry. In 1986, it began providing OEM valve design and manufacturing services for numerous international brands. Leveraging the Union Tech Valve Department, comprised of top-tier mechanical engineers, experienced valve specialists, and skilled manufacturing engineers, and the accumulated experience of over 100,000 valves shipped since 1986, we launched the independent Union Tech brand of valves in 2003. After nearly 40 years of steady growth, Union Tech has become a multinational corporation, providing integrated and localized valve production, sales, and service for a wide range of industries worldwide. It has become a leading supplier of valves for demanding applications with international influence. Union Tech has a factory in China, and produces and tests in China according to US production quality standards, which greatly reduces prices and shortens delivery time.
