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.

Published coverage 5 series-level entries

Decision basis Complete code + interfaces + application

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 aliases Atos, Atos Hydraulics
Product family Separate the reference into the relevant valve, pump, motor or service-part group.
Complete identifier Preserve every suffix, revision, material number and option character visible on the nameplate or document.
Installed evidence Compare interfaces, operating conditions and application before any replacement statement is released.

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.

REVIEW BASIS

Use the manufacturer portfolio to identify the family—not to infer an automatic replacement.

The external source below provides manufacturer context for product identification. Hydraulic Match's page independently organizes customer-submitted references. It does not reproduce a full catalog, certify current production status or establish authorization, inventory or interchangeability.
