INDEPENDENT MODEL-CODE AND SOURCING REVIEW
Atos references accepted for structured RFQ review.
Atos electronic valve reviews require the complete valve and driver references, command signal, feedback option and machine-control context.
PRODUCT COVERAGE
What can enter the review process
CATEGORY ROUTES
Review Atos references by product category
Start from the product category that matches the installed component, then submit the complete model code.
IDENTIFICATION HIERARCHY
How a Atos 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 aliasesAtos, Atos Hydraulics
- 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.
PRODUCT AND REPLACEMENT ROUTES
Atos valve replacement review
Atos directional, proportional and pressure-control valves are reviewed by complete code, function, mounting size, electronics, pressure and flow.
SERIES DIRECTORY
Commonly submitted Atos 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 |
|---|---|---|---|
| DHI / DHE | Directional valves | Spool, voltage, connector and mounting | Send full code |
| DHZO / DKZOR | Proportional valves | Signal, spool, electronics and flow | Send full code |
| DPZO | Pilot-operated proportional valves | Driver, feedback and system dynamics | Send full code |
| PVPC | Piston pumps | Control, displacement and pressure setting | Send full code |
| PFG / PFED | Fixed-displacement pumps | Displacement, shaft and pump combination | 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 |
|---|---|---|
| DHI / DHE | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| DHZO / DKZOR | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| DPZO | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| PVPC | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| PFG / PFED | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
