THE REQUIREMENT FOR MORE COMPACT CONSTRUCTION IN MOBILE TOOLS IS
INCREASINGLY COMMON. THE RIGHT COMPONENTS CAN HELP TO MEET THIS
effect is seen on vehicle design, but also in the
larger and more powerful machines being built.
With more powerful vehicles, the focus is on
movements that have to be carried out faster and
more efficiently.
All designers are aware that quick movements
require considerable operating power, which
results in high costs. In order to keep the costs or
investments as low as possible, one looks for low
weight products that bring high volume flows to
the consumer with as little loss of power as
possible through the various bores and control
openings in the hydraulic control unit. For the
operator of the plant, energy loss always entails
costs. It is possible, that a certain energy loss is

Changes in the virtual world are having
more and more impact on hydraulics. The

accepted, so that a certain task can be carried out
more rapidly. If the hourly rate of the machine is
higher than the costs of the energy loss, this is an
advantage for the operator. Nonetheless the
energy loss has to be kept within limits.
Wandfluh up to now was known as a
manufacturer of small valves. The field of
application during the past years has shifted towards
mobile applications. Applications in the areas of
earth movement, crane construction, materials
handling or mobile underground installations
belonging here. These are also the application
fields, in which large volume flows are necessary.
Compact construction
The requirement for a compact construction in
mobile tools is increasing. For this reason, the
Wandfluh company has complemented the
screw-in valve range in the ISO-sizes M33 and
M42 with a spool valve cartridge.
The construction of valve functions in blocks
made of steel or aluminum enables an individual
adaptation to the available space, without having
to accept losses in the flexibility of the functions.
The well-proven screw-in technology here
provides the possibility of constructing flexible
solutions adapted to the application. Because of
the internal connections between the individual
valves, the block construction has the advantage
of far fewer leakage points when directly
compared to the solution of aligned and flanged
valve elements. This block construction simplifies
the decentralization of the control functions.
As a result the designer is given then ability to
