DOUBLE FLANGED BUTTERFLY VALVE F012-K1/ WN The shaft sealing of centric soft-seated butterfly valves is primarily effected by the surface pressure between the valve disc and the liner. Especially with large nominal diameters from DN600 and high pressures more than 16 bar, the simple surface pressure may no longer be sufficient. EBRO has designed an adjustable shaft seal which makes it possible to increase the surface pressure in the shaft passage area so even large valves can operate at pressures of up to 25 bar. A further advantage of this design is that the shaft seal can be adjusted by...

DOUBLE FLANGED BUTTERFLY VALVE F012-K1/ WN TORQUE - The values listed in the table are initial breakaway torques, taken with liquids and lubricant media. - Please regard these as approximate values, as the objective value depends on different factors like pressure, medium, rubber, quality, temperature ... etc. - Our engineers look forward to help you with exact values for your application. Adapted Disc Size Pressure Rating DN [mm] Bigger sizes upon request Kv-VALUES - The Kv-value [m³ per hour] is the flow of water at a temperature of 5°C to 30°C (41°F to 86°F) at ∆p of 1 bar - The...
