INDEPENDENT MODEL-CODE AND SOURCING REVIEW
NACHI references accepted for structured RFQ review.
NACHI inquiries are separated by pump or valve family, complete design code and installation evidence before dimensional or functional comparison.
PRODUCT COVERAGE
What can enter the review process
CATEGORY ROUTES
Review NACHI references by product category
Start from the product category that matches the installed component, then submit the complete model code.
IDENTIFICATION HIERARCHY
How a NACHI 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 aliasesNACHI, Nachi-Fujikoshi
- 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 NACHI 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 |
|---|---|---|---|
| PVS / PZS / PZ | Piston pumps | Displacement, control, pressure and mounting | Send full code |
| VDS / VDR / VDC | Vane pumps | Pressure setting, design series and mounting | Send full code |
| IPH | Internal gear pumps | Pump size, section count and shaft | Send full code |
| G01 / G03 / G04 | Modular valves | Function, stack size and mounting | Send full code |
| SA / SS / SL | Solenoid valves | Spool, voltage, connector and size | 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 |
|---|---|---|
| PVS / PZS / PZ | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| VDS / VDR / VDC | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| IPH | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| G01 / G03 / G04 | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| SA / SS / SL | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
REQUIRED EVIDENCE
Prepare before quotation
- Complete model and design code
- Nameplate and installation photos
- Pump adjustment or valve function
- Electrical data where applicable
- Operating pressure and fluid
APPLICATION ROUTING
Common inquiry environments
- Machine tools
- Industrial machinery
- Compact power units
- Factory maintenance
Submit a NACHI reference for review.: Send the complete code, nameplate, quantity, destination and application. We separate confirmed facts, open points and conditional compatibility in the response.
