The main feature of the NFG fully welded ball valve is the manufacture of the body by means of parts welded together. This method guarantees the absence of leakages all along the valve life, with no requirement for maintenance operations. This is a highly important requisite especially for ball valves installed onto underground pipelines.
The NFG fully welded ball valve summarizes a multi-year experience in the gas distribution and district heating fields, which has made possible to identify the most innovative solutions for these specific applications. The fully welded ball valve is available in the sizes up to DN 300 (12) full bore and DN 400 (16x12) reduced bore, with designs and configurations varying according to diameter and service.
