The maintenance of the electric linear actuator

With the help of the built-in data memory, the operator can record the data measured by the torque sensing device during each action of the electric linear actuator. These data can be used to monitor the operation status of the valve, prompt whether the valve needs maintenance, or use these data to diagnose the valve.

The following data can be diagnosed for the electric linear actuator:
1. Friction of valve seal or packing

2. Friction torque of valve stem and valve bearing

3. Seat friction

4. Friction during valve operation

5. Dynamic force of valve core

6. Stem thread friction(electric linear actuator)

7. Valve stem position(electric linear actuator)
