ASTECH VALVE CO., LTD.

AST was established in March 1999, focusing on valve design, manufacturing, and sales. AVC was founded in January 2010 and became part of the parent company, ASTIC. AVC specializes in the design and manufacture of Wafer Type Check Valves and Metal Seat Ball Valves. In June 2011, the company received ISO 9001 certification from Anglo Japanese American Registrars Taiwan Limited, with plans to achieve CE and API certifications in 2013. To meet the demand of the Japanese market, a branch office was established in November 2004, responsible for sales, quality assurance, warehousing, and delivery. The company is committed to stability and professional quality, which guide our strategic direction. We aim to establish independent AST and AVC brands while expanding into the East Asia, Southeast Asia, and Middle East markets. Additionally, we are seeking OEM and ODM partners and planning to enter the European and American markets.
