6 -INED BUTTERFY VAVE T 212 TORQUE - The torque values specified (MD) are based on dry media and are measured with air at a temperature of 20 C. - The values specified are based on the initial breakaway toque (disc disengages from seat, torque then drops). MD (Nm) Dynamic torque specification available upon request. Regarding the dimensioning of actuators, please contact our engineers. PRESSURE/TEMPERA- TURE DIAGRAM* Pressure (bar) to 00, installation between flanges 50 to, installation between flanges to end of line service Temperature ( C) * For valves with silicone elastomer inserts. v-vaues - The v -value (m 3 per hour) is the flow of water at a temperature of 5 C to 30 C ( 1 F to F) at p of 1 bar. - The v -values specified are based on tests carried out by the Delfter ydraulics aboratories, the Netherlands v-values (Valve fully opened) v -values metal disc v -values -disc Permissible velocity of flow Vmax,5 m/s for liquids and Vmax 70 m/s for gases. - The throttle function is linear at an angle 30 to Avoid cavitation!
