The actuator start torque must be greater than thevalve start torque.End (run) torque is the torque required to complete theactuation. The actuator end torque must be greater than thevalve end torque.Factors that Affect Operating TorqueFrequency of UseOperating torque typically increases as the time intervalbetween cycles increases.For applications in which valves are cycled less frequentlythan noted in the Calculating Operating Torqueinstructions, contact your authorized Swagelok sales andservice representative.Cycle WearContacting surfaces—valve ball, seat, and body, forexample—gradually wear as valves are actuated repeatedly,resulting in increased friction and operating torque. Actuationspeed may influence the rate of valve wear as well.For applications in which valves are actuated rapidly orrepeatedly—more often than once per hour—contact yourauthorized Swagelok representative.Seat or Packing MaterialIn some ball valve designs, friction between ball and seat orpacking affects operating torque, which varies with materialand lubricant.System PressureHigher pressures cause greater contact forces and friction,resulting in higher operating torque.System TemperatureThe values given in the tables that follow were generated atroom temperature. Lower or higher temperatures, dependingon the valve design, can cause increased operating torque.System MediaThe values given in the tables that follow were generated withclean, dry nitrogen gas. Different system fluids have varyingviscosities, bringing about different levels of friction andaffecting operating torque. Some lightweight oils may reduceoperating torque. Dirty, abrasive, or highly viscous fluids mayincrease operating torque.
