Deskripsi
Diaphragm Valve
Model : BG46J-16 DN100
Brand : Northern Valve Industry Co., Ltd.
Product Overview
The BG46J-16 DN100 is a manual flanged diaphragm valve engineered for high wear resistance in demanding fluid systems. It features a rubber-lined or fluoropolymer-lined body, isolating the working fluid from the valve mechanism. This makes it ideal for slurry, acidic, alkaline, and particulate-laden flows in industries like mining, chemical processing, and wastewater treatment.
