Bio-clean diaphragm valve with clamp connection, corrosion-resistant valve.
Many delivery achievements for pharmaceutical and food plants, as well as high-purity chemical solutions! It can completely block corrosive fluids.
At Nippon Diaphragm Valve, we handle "clamp-connected corrosion-resistant valves" with a body made of fluororesin (ETFE) lining. These valves are suitable for countermeasures against corrosive fluids in sanitary piping, gap corrosion due to chloride ions, and metal ion elution. With the diaphragm valve's features of "air tightness" + "corrosion resistance," they can completely shut off corrosive fluids. We have many achievements not only in pharmaceutical and food plants but also in high-purity chemical lines. 【Features】 ■ Body material: SUS316L ■ Lining material: ETFE ■ Connection method: Clamp joint (ISO2852) ■ Applicable nominal diameter: 25A to 65A (1S to 2.5S) *For more details, please refer to the PDF materials or feel free to contact us.
