All torque values shown on chart are for "wet" (water and
other non-lubricating media) on-off service. For "dry" service
(on-lubricating, dry gas media), multiply values by 1.6. For "lubed"
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.
