Week 4, 27th April

The preventative maintenance that I participated in is steam turbine generator and heat recovery steam generator (HRSG) 1&2 motorized actuators inspection. We need to check the feedback availability whether it is close or open and check for the defects.

The actuators that used in the plant mostly is limitorque L120 series actuators. It can be used to control butterfly, ball, and plug valves which requires 90 degrees movement.
