INDEPENDENT MODEL-CODE AND SOURCING REVIEW
Moog references accepted for structured RFQ review.
Moog products are treated as high-risk motion-control components. No alternative is proposed without electronics, signal, feedback, cleanliness and dynamic-performance information.
PRODUCT COVERAGE
What can enter the review process
CATEGORY ROUTES
Review Moog references by product category
Start from the product category that matches the installed component, then submit the complete model code.
IDENTIFICATION HIERARCHY
How a Moog reference moves from a name to a decision
Brand recognition is only the first routing step. The review narrows the inquiry from manufacturer name to product family, series, complete code and finally the installed interfaces and duty.
- Brand and aliasesMoog, Moog Industrial
- Product familySeparate the reference into the relevant valve, pump, motor or service-part group.
- Complete identifierPreserve every suffix, revision, material number and option character visible on the nameplate or document.
- Installed evidenceCompare interfaces, operating conditions and application before any replacement statement is released.
SERIES DIRECTORY
Commonly submitted Moog references
The table is an inquiry-routing index, not a compatibility chart. Every suffix and installed interface remains subject to review.
| Series reference | Product type | Primary review focus | RFQ route |
|---|---|---|---|
| G761 | Mechanical-feedback servo valves | Flow rating, coil, null and mounting | Send full code |
| D633 / D634 | Direct-drive servo valves | Signal, feedback and dynamic requirement | Send full code |
| D661 / D765 | Servo-proportional valves | Pilot stage, electronics and fail-safe behavior | Send full code |
| RKP / RKP-D | Radial piston pumps | Displacement, control and electronics | Send full code |
FAILURE-MODE REVIEW
Why the series rows need different evidence
These checks explain the decision risk behind each published reference. They are review rules, not a claim that every listed configuration is available.
| Reference | Mismatch risk | Evidence needed for release |
|---|---|---|
| G761 | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| D633 / D634 | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| D661 / D765 | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| RKP / RKP-D | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
REQUIRED EVIDENCE
