3-Piece Welded Ball Valves: Introduction & Technical Parameters

3-piece welded ball valves are composed of three-section ball valves. The valve body can withstand 1000WOG pressure, with socket weld or butt weld connections at both ends, facilitating connection with pipelines. The valve body materials include WCB, SUS304, SUS316 and SUS316L stainless steel. They are mostly used in media with temperatures below 250 degrees Celsius and have the characteristics of compact structure, small space occupation and convenient installation.
