double flange eccentric butterfly valve

double flange eccentric butterfly valve   DN150 upon to DN1200, all the disc will be designed to a flat shape. For valve size DN1200 and above ( only for valves made of ductile iron), the butterfly valve disc will be designed to a flying-disc shape, which will ensure the valves have very low head loss comparing to other ordinary design. Materials of the butterfly valves BDOY: GGG40, WCB, CF8, CF8M…. DISC: GGG40, WCB, CF8, CF8M… SHAFT: SS410/420, SS304. SS316, 17-4PH SEAL: NBR, EPDM, PTFE Field of application ;  In water supply system for the isolation of pipes carrying potable water, sewage ad sea water ; In chemical Engineering for isolating all kind of liquid and gaseous media ; In power Stations for cooling water and condensate pipes ; For irrigation schemes , In air conditioning and ventilation plant ; Euipmented with high performance electro-hydrulic system,
