Proportional Valve
PVX
With the introduction of our new PVX proportional
valve, Danfoss introduces an industry-changing
advancement in valve technology for off-highway
applications.
The PVX valve features a robust 2-spool hydraulic
design with integrated software and sensors that
enable intelligent valve configuration and superior
control.
This unprecedented sophisticated valve solution will
offer OEMs reduced time to market, decreased
development costs, unsurpassed adaptive
performance, higher energy efficiency and superior
operator productivity.
To provide maximum system design flexibility, the
PVX is designed as a sectional valve, supporting up to
12 functions.
