Detail Information

Product Name: Sanitary Diaphragm Valve, Stainless Steel
Body Material: AISI 316L, EN 1.4404
Diaphragm Material: Rubber
Size: DN25, 1 Inch
Pressure: PN10, Class 150 LB

The Sanitary Diaphragm Valve (or Membrane Valve) features a valve body with two or more ports, an elastomeric diaphragm, and a “weir” or saddle seat that the diaphragm closes to control the flow. It provides both a body seal and a seat seal, ensuring no external contact, making it ideal for aseptic processes in biopharmaceutical industries. The valve body is constructed from Stainless Steel AISI 316L and is available with manual or pneumatic operation, with automation options through a valve positioner. Connection ends are available in tri-clamp, butt weld, or thread configurations.
