Double Acting Actuator Actuators and Controls With reference to the above diagram it can be noted that the torque of a double acting actuator remains constant throughout the complete cycle. The user can decide which model to choose according to their own specific requirements, using the following guidelines: 1. Define the maximum torque of the valve to automate. 2. To obtain a safety factor,increase the torque value chosen by 25%-50% (subject to the type of valve and working conditions). 3. Once the torque value is obtained consult the torque chart in the corresponding air pressure column, find a torque value exceeding the valve requirement.
