Macro Butterfly valves Category Cast iron butterfly valves Cast iron butterfly valve for mounting between flanges, “Wafer” type ITEM 375 Body: Cast iron Butterfly: Cast iron Liner: see table ITEM 376 Body: Cast iron Butterfly: CF8M (316 S.S.) Liner: see table ITEM 377 Body: Cast iron Butterfly: Bronze aluminium Liner: see table 1. EN ISO 5211 top mounting Easy coupling with every kind of drives. 2. Three guiding bushings on the shaft It grants a perfect alignment of the shaft on the body and prevents oscillations even with high pressure. Less friction between the shaft and body. 3. Vulcanized liner on rigid ring Less deformation of the liner Easy assembly / disassembly of the liner for maintenance No deformation of the liner between the flanges during assembly Greater dimensional accuracy during the injection/molding 4. Shaft in 2 pieces without fixing components Easy assembly / disassembly of the disc for maintenance Higher Kv thanks to the central section of the disk thinner than a valve with a single shaft 5. Lapped surface of the disc's circumference Better tightness and less wear of the liner Lower torque due to less friction between the disc and liner Wide range of LINER materials Various applications possibility ATEX Certificate Installation is allowed in a potential explosive environment PED Certificate Full compliance with European Safety Standards for Pressure Equipment
