This is normally the breakaway torque after the valve has been stationary for the longest period of time. pply an appropriate service factor to the valve torque to determine the required torque: 20% for normal operation; 50% for dry, dirty or infrequent operation; and 100% for emergency shutoff or throttling control valves Double cting Selection Refer to Double cting Torque Chart. Read down the applicable ir column to the first torque that exceeds the required torque, then left to the actuator size. Return Selection Refer to the Return Torque Chart. Read down the End column to the first torque that exceeds the required torque, then right to the applicable ir End column. If the ir End torque also exceeds the required torque, read left to the actuator size and spring set. If not, move down the chart one actuator size at a time and repeat, until both torques exceed the required torque. 6

This is due to spring compression during air cycle and spring uncoiling during spring cycle of actuation.
