The G Series W-Welded Body Line Ball Valves manufactured by SNJ are designed to ANSI / ANSI standards and API6D specifications. Product structure using a fixed ball structure, and well-designed and finite element numerical simulation. Manufacturing CNC machining center processing, valve welding process optimization, and process evaluation and assessment, the entire design, manufacturing process strictly implement the quality assurance system to ensure product reliability and quality stability. The successful development of fully welded valve body line ball valve broke the technical monopoly of foreign companies, enhanced the technological innovation of domestic valve enterprises and enhanced the capability of independent development, contributing to the localization of major equipment of pipeline industry. The domestic ball valve design and manufacturing level to a new level. By the China Machinery Industry Federation presided over the "all-welded body valve New product prototype ball valve identification." Products identified: "fully welded valve body valve" the leading integrated technology, design, manufacture reached the international advanced level, and have independent intellectual property rights. The fully welded body line ball valve has been selected for the following projects and projects: Yangzhou City Gas, Sinopec Shijiazhuang - Taiyuan Oil Pipeline, PetroChina Lanzhou - Yinchuan Gas Pipeline, and CNOOC Zhongshan LNG Utilization Project.
