4.3.3.1 PVG VALVE BLOCK
The PVG valve block on the Scorpion boom
mower is the machine's primary valve block,
developed in collaboration with Danfoss.
The PVG valve block consists of a
configurable modular structure, which
makes it possible to collect all the hydraulic
primary functions of the Scorpion boom
mower in one valve block.
The valve block receives and controls the
incoming flow from the machine's hydraulic
pump at 115 l/min @ 220 bar or 125 l/min
@ 315 bar
The valve block always prioritizes the attachment tool first and distributes the right amount of oil to the
attachment tool from: 50 l/min @ 180 bar, and up to
→ 85 l/min @ 315 bar.

The remaining amount of oil on the machine is used to control the various modules, and thereby
functions/movements on the boom mower.
4.3.3.2 ACCUMULATOR FOR HYDRAULIC FLOAT OF ARM
The accumulator has a charging pressure of 32
bar and is activated when the "Float of arm"
function is used on the Scorpion boom mower.
See section: Control panel and joystick – side 38-
47 + Operating and driving instructions – side 95-

Here, the accumulator creates a back pressure in
the lifting cylinder of the arm, which gives the arm
a soft springy effect, so that an attachment tool
used along the ground (e.g., GreenTec FR Flail
Mower) can avoid up to 10-15 cm unevenness in
the ground surface.
The accumulator is controlled using a hydraulic
valve with electric coil that communicates with the
machine's electrical control system.

These specifications depend on the GreenTec attachment tool on the Scorpion 5-830 boom mower.
