Wrong actuator settings can cause real damage
Valve actuator performance is defined by more than torque. The correct closing time protects pipelines, reduces hydraulic stress, and helps maintain reliable system operation.
When it comes to valve actuators, torque usually gets most of the attention, but closing time deserves just as much consideration.
If a valve closes too quickly, particularly during the final part of its stroke, the pipeline can experience:- Water hammer
- Additional stress on pipelines, fittings, and equipment
- Disturbances to downstream operations
Selecting an actuator isn't only about matching torque or flange dimensions, it's also about achieving the right closing profile for the application.
Depending on the system, an actuator may require commissioning adjustments or a different gear ratio to achieve:- Controlled closing time
- Stable valve operation throughout the stroke
- Performance aligned with system hydraulics
At AVK Saudi, actuator selection goes beyond torque ratings. By considering closing time, gear ratio and application requirements, engineers can achieve controlled valve operation, support pipeline reliability and maintain consistent system performance throughout the asset's service life.
