Electrical actuation

Electrical control of PVG

30 | © Danfoss | August 2017
Valve actuation with electrical actuators has been supported by Danfoss for a long time. The actuation
can be controlled directly by joystick, by a PLUS+1® controller or by a broad range of third part
controllers. The actuator controls the spool by building up pilot oil pressure on the end of the spool. For
the PVE a pilot oil pressure between 10 and 15 bar is used. For the PVHC a pilot oil pressure between 20
and 25 bar is used.
