Control Valve Selection Chapter 5. Control Valve Selection Actuator Sizing Actuators are selected by matching the force required to stroke the valve with an actuator that can supply that force. For rotary valves a similar process matches the torque required to stroke the valve with an actuator that will supply that torque. The same fundamental process is used for pneumatic electric and electrohydraulic actuators. Globe Valves The
