- The output of the actuator is greater than the load of the valve and is reasonably matched.
- When checking the standard combination, it is necessary to consider whether the allowable pressure difference specified by the valve meets the process requirements. When the pressure difference is large, the imbalance force of the valve core should be calculated.
- It is necessary to consider whether the response speed of the actuator meets the requirements of the process operation, especially the electric actuator.
