Ball valve

manualfor natural gasfully-welded

The twenty-year long experience of Negri Fratelli at manufacturing fully welded ball valves for natural gas has produced a new solution: a carbon steel ball valve with PE ends suitable for direct installation onto PE pipelines, without requiring the additional application of PE/Steel transition fittings. Such new product combines the superior quality and highest seal capacity, typical of the NFG fully welded ball valves, with the simplest installation procedure deriving from the presence of the built-in PE ends. Additional pluses of such valve are the compact dimensions and the possibility to enrich the valve with all the accessories available for the fully welded line (fixed, adjustable or telescopic stem extensions, built-in vents complete with steel ball valve, fixed or removable gear operators, etc.).
