SNJ all welded valve body line ball valve


The G-Series W-type all-welded body line ball valve manufactured by SNJ is designed to meet US ANSI standards and API6D specifications. The product structure uses a fixed ball structure and has been carefully designed and finite element numerical simulation. The manufacturing adopts CNC machining center processing, valve body welding process optimization, and process evaluation and evaluation. The entire design and manufacturing process strictly implements the quality assurance system to ensure product reliability and quality stability.

The successful development of the all-welded valve body ball valve has broken the technological monopoly of foreign companies, enhanced the technical innovation of domestic valve enterprises, enhanced the ability of independent development, and contributed to the localization of major equipment in the pipeline industry. Raise the design and manufacturing level of domestic ball valves to a new level.

The “Production Appraisal Meeting for New Products of Fully Welded Valve Body Line Ball Valves” hosted by China Machinery Industry Federation. The product has been certified: the comprehensive technology of “all welded valve body pipeline ball valve” is domestically leading, and the design and manufacture have reached the international advanced level and have independent intellectual property rights.

The fully welded valve body line ball valve has been selected by the following projects and projects: Yangzhou City Gas, Sinopec Shijiazhuang-Taiyuan Product Oil Pipeline, PetroChina Lanzhou-Yinchuan Gas Pipeline, CNOOC Zhongshan LNG Utilization Project.
