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.
