Danfoss and the Series 45 offer awide range of displacements andcontrols. The ability to integrate
Series 45 with PVG and PLUS+1®
solutions offers an infinite numberof control combinations and gives
you the ability to tune them to fit
your specific needs.

Efficient,electric controls
PLUS+1® Compliance
Optimizing systems around electronic controls is the future ofmobile machinery. When combined, Series 45 and the PLUS+1
system allow for easy integration with other PLUS+1 Compliant
Danfoss products, allowing you to quickly build customized
applications while reducing the cost and development timenormally associated with programming.
With electronic control, load-sensing and a flexible, modular design,
PVG valves enable you to meet these challenges.
Electric on/off normally open andnormally closed with pressure compensating
Operates as a PC- type control with the ability to switch to low
pressure standby. Ideal for unloading the hydraulic system
during engine start up.

Electric on/off normally closed withpressure compensating and load sensing
Operates as a PC/LS control with the ability to override the PC
control to operate in low pressure standby. Ideal for unloading
the hydraulic system during engine start up while maintaining
an LS system.
Electronic proportional pressure control,
normally closed and normally open
Control operating pressure proportionally with an infinite range
between low pressure standby and high pressure setting, idealfor modulating fan drives.
