Sheet 01
On the unit
We find the part, check it against the parts breakdown for your engine model, and install and test it on site if you want.
- 01What it does. The servo valve turns a small current from the control into hydraulic flow that moves the actuator. The LVDT or RVDT reports the position back. Control, servo and feedback form one closed loop: a change in any of them changes how the loop behaves.
- 02Where it sits. VSV actuators on the LM2500, VSV, VIGV and VBV actuators on the LM6000, fuel metering valves on both, and electro-hydraulic actuators on steam turbine and compressor controls.
- 03What goes wrong. A null bias that drifts, an LVDT that reads differently from its twin, an open servo coil, a cable that breaks under vibration, contamination that makes the servo stick, and a loop that hunts after a replacement because the calibration was not redone.
- 04How we check it on site. Coil resistance and insulation, LVDT excitation and output, end-point and linearity calibration with the control, null current, step response from a trend, and redundant channels compared over the full stroke.
