PRODUCT DESCRIPTION
TECOFI VP4548-08 Flanged Butterfly Valve, Ductile Iron Disc, Gearbox
VP4548-08 is a Tecofi (France) flanged butterfly valve of the Tecfly VP range: ductile iron EN-GJS-400 (GGG40) body, ductile iron EN-GJS-400 (GGG40) disc, Heat EPDM seat, operated by a gearbox with a cast iron handwheel. Size range DN50–DN300, maximum working pressure 16 bar, working temperature -15°C / +130°C (peak -30°C / +150°C).
How does VP4548-08 differ from VP4548-02?
VP4548-08 differs from VP4548-02 in the operator: VP4548-08 uses a gearbox with a cast iron handwheel, while VP4548-02 uses a ductile iron handle. Body, disc, seat, size range (DN50–DN300), maximum working pressure of 16 bar and working temperature are the same for both codes per the Tecofi datasheet. VP4548-08 weighs 8–59.8 kg depending on size, against 5.39–51.5 kg for VP4548-02.
