Bola-Tek Sanitary Ball ValvesFor almost 20 years, Taiwan-based BOLA-TEK has produced all kinds of stainless-steel ball valves, including both threaded and flanged; gate, globe and check valves; OEM parts such as balls, stems and castings; and increasingly sophisticated high-pressure valves. All ball valves are guaranteed, and are suitable for many industrial- or sanitary-fluid applications. Threaded ball valves range from sanitary 3-piece at rated at 1000 psi to 2- and 3-piece high-pressure valves rated at 6000 psi.
