About Us

The company was established as Main Pillar Enterprise in Taichung in 1983. In response to the government's improvement of production quality, we produced the hand tool hardware by YF registered trademark, which made us one of the well-known and major hardware manufacturers in Taiwan. In order to upgrade our products, we started to manufacture stainless steel flanges in 1988. In order to meet the demands of domestic and foreign markets, we purchased CNC computer lathes and CNC center cutting machines for mass production. We began to export our product to Europe and the United States, building up the foundation of the export market. After years of efforts to implement factory standardization and comprehensive quality control, our products have developed from the early general industrial valves to various higher spec valves, such as semiconductor ultra-clean ball valves, sanitary ball valves, seawater desalination ball valves, API607 fire safe ball valves, cryogenic valves, automatic control valves and other products.
Now Mizup products are broadly used in both domestic and foreign markets. We will continue to meet the expectations of customers and concentrate on the stable supply of higher quality products.
