Dear All

Can any one share BOM or document mentioning MOOG Servo model to be used on Woodward Gas Control Valves Part Number 9904-755 & 9904-756.
We have two different MOOG Servo models G771K201A & G772K240A. The applicable Woodward manual 26231 Rev AD suggests Hydraulic supply system capable of supplying 38 L/min flow (corresponding to MOOG G772 model) whereas older version of this manual mentions 17 L/min flow (corresponding to MOOG G771 model) requirement

 

Have u found the BOM related to both GCV part numbers?

 

Use G772K240A when you have at least 38 L/min hydraulic flow (per Rev AD). Use G771K201A only if you’re restricted to about 17 L/min and are strictly following older manual editions. Contact Woodward Support directly with your valve part numbers (9904‑755/756) and relevant serial numbers. They can confirm the recommended MOOG servo model and provide you with a proper BOM document.
