INDEPENDENT MODEL-CODE AND SOURCING REVIEW
Parker references accepted for structured RFQ review.
Parker references span multiple hydraulic product groups. Review starts by separating the product family, exact code, mounting standard and installed options.
PRODUCT COVERAGE
What can enter the review process
CATEGORY ROUTES
Review Parker references by product category
Start from the product category that matches the installed component, then submit the complete model code.
IDENTIFICATION HIERARCHY
How a Parker 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 aliasesParker, Parker Hannifin, Parker Denison
- 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 Parker 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 |
|---|---|---|---|
| D1VW / D3W | Directional valves | Spool, size, voltage and mounting | Send full code |
| D41 / D91 | Proportional valves | Signal, electronics, feedback and flow requirement | Send full code |
| PAVC / PVP | Piston pumps | Control, displacement, shaft and ports | Send full code |
| T6 / T7 | Vane pumps | Cartridge, rotation and port arrangement | Send full code |
| F11 / F12 | Bent-axis units | Pump or motor function, speed and mounting | 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 |
|---|---|---|
| D1VW / D3W | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| D41 / D91 | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| PAVC / PVP | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| T6 / T7 | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| F11 / F12 | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
