04.100 Fucoli butterfly valves with ductile iron seat and gearbox IP68 PN10/16

The butterfly valve is intended for isolation and regulation in drinking water pipelines and for neutral liquids, in sizes DN 150 to DN 1000. The design is double eccentric with bidirectional sealing, so the valve seals in both flow directions. The body is cast in ductile iron EN-GJS-500-7 and powder coated inside and outside with drinking-water-approved epoxy RAL 5005, minimum 250 µm (GSK-approved). The valve is designed to EN 1074-1/2 and EN 593, with flange drilling to EN 1092-2 and face-to-face length to EN 558 table 2 series 14. The working temperature is 0–70°C, no frost. In the 04.100 (Duplex 500), the seat is ductile iron and cast directly into the valve body. If you need an acid-resistant seat, choose 04.102 instead. The valve is always supplied with an acid-resistant stem and stem sleeve for the longest possible service life. The version with the IP68 gearbox from Auma is intended for underground installation and has an ISO flange for the actuator, so the valve can be motorised. For above-ground installation, the same valve is available with a handwheel and IP67 gearbox.
