Valve Seating Torques (in Lbs.)
The above torque values are only available for ANSI Class 125 Working pressure designed butterfly valves size from 2" to30". Or for PN16 working pressure designed valves size from DN50 to DN300.All torque values shown on chart are for "wet" (water and other non-lubricating medium) on-off service. For "dry" service( non-lubricating, dry gas media), multiply values by 1.6..For "lubricating medium" service (clean, non-abrasive lubricating media), multiply values by 0.85. When sizing actuators for single valve applications, multiply values by 1.25.When sizing for 3-way("tee") applications multiply values by 1.5. Under certain conditions, hydrodynamic torque can meet or exceed seating and unseating torques. When designing valve systems, hydrodynamic torque must be considered to help ensure correct selection of application.
