Double-Acting Valve
PVBZ-HD
Unique Flexibility
We introduced to the market our first PVG 32 valve
two decades ago with a range of high performance
electrical actuator options.
The two valve options included in the Danfoss hitch
system are the PVBZ-HS single-acting and the PVBZHD double-acting valves. ThePVBZ-HD matches the
market standard whereby implements are raised
hydraulically and lowered only by the pull of their
own weight, thePVBZ-HD has the unique ability to
raise, lower and press down.
Best Performance
The benefits of the PVBZ-HD reflect another
departure from old hitch norms – increased comfort
when attaching implements due to the same speed
up and down and safer detachment of heavy
implements from the driver’s seat. Once in work
mode, the double-acting valve switches automatically
over to a single-acting operation for normal field
performance.
Containing many of the same components as Danfoss
auxiliary valves, the hitch valves are easy to integrate
in an existing hydraulic system. The technology on
which they are based is long since proven. That leaves
a smart new hitch with the best of everything.
