Today, OEMs are faced with two compelling
events that challenge vehicle design
and development: increasingly stringent
engine emissions regulations (Tier IV/Stage
IV), and new vehicle safety legislation.
To compensate for the reduced power
levels of emissions-compliant engines,
overall vehicle efficiency must be optimized.
Intelligent system solutions are also
needed to comply with the new safety
standards and help speed up vehicle
design and qualification.
With electronic control, load-sensing and
a flexible, modular design, our PVG load-
independent proportional valves enable
our customers to meet these challenges.
FlexibleSystemDesignOur portfolio of PVG valves provide
customers with exceptional flexibility
in system design. The modular design
of PVG accommodates future control
variations and gives you an almost infinite
number of configurations. Load-sensing
technology also means that wear and
tear on other components in the system
is reduced, which helps extend vehicle
life. Providing outstanding control, day in
and day out, our high-quality valves are
built to last.
AdvancedElectronicActuatorsWe offer a full range of electronic actuators,
from simple on/off solutions, to state-of-
the-art CAN bus communication.
Our advanced PVED-CC and PVED-CX
digital actuators are specifically designed
for J1939/ISOBUS Protocol and CANopen
systems. PVED-CX is also SIL 2 certified
(Safety Integrity Level 2 according to IEC
61508), to help comply with the demands
of the European Machinery Directive
2006/42/EC and reduce the time and costs
associated with system qualification and
vehicle certification.
GlobalManufacturingandSupportOur worldwide network of sales companies,
distributors, and authorized service centers
is ready with after-sales support and product
service when you need it. Contact your
local Sauer-Danfoss representative to
find out how we can help increase overall
vehicle efficiency, reduce costs and improve
productivity.
Outstanding Control for all Your Application Needs

PVG 32
Our PVG 32 range of load-independent proportional valves operate
with compensated flow up to 130 l/min [34.4 gal/min] and work
port pressure up to 400 bar [5800 psi]. Designed for maximum
flexibility, PVG 32 valves reduce heat generation and increase
efficiency and power density, which helps to meet the challenges
posed by new engine emissions legislation.
From simple load-sensing, to advanced electrically controlled load-
independent proportional valves, the modular design of PVG 32
makes it possible to design a valve group that precisely meets all
of your application requirements. No matter which combination of
valves is specified, the compact, external dimensions of the valve
remain unchanged.

PVG 100
Our highly efficient post-compensated proportional valve PVG 100
provides compensated flow up to 180 l/min [47.6 gal/min] and
work port pressure up to 350 bar [5076 psi]. Post-compensated
flow sharing valves are able to decrease oil flow to all basic work
functions in case of reduced supply from the pump. Flow sharing
enables design engineers to decrease pump size, while still
maintaining optimal machine performance. Downsizing the pump
provides incremental power and cost savings when using a variable
displacement pump and substantial power savings when using a
fixed displacement pump.
New engine emissions regulations (Tier IV/Stage IV) create
a number of challenges for vehicle designers. These include
additional heat rejection, net vehicle power reduction and reduced
hydraulic flow. To help meet these challenges, flow sharing can be
used to help improve overall vehicle efficiency – reducing wasted
power – while increasing vehicle productivity.

PVG 120
Our PVG 120 load-independent proportional valve has been
designed for the toughest applications with compensated flow up

PVED – Advanced Digital Control
Figure 4: XXXXXXXX From simple configurations to advanced digital systems.
Our portfolio of high-performance PVE actuators features PVED-CC
and PVED-CX, advanced digital actuators specifically designed for
J1939/ISOBUS Protocol and CANopen systems. Along with analogue
position control circuits, PVED-CC and CX also contain a digital circuit
that enables flow control via CAN communication. The result is
cutting-edge digital control, advanced diagnostic functions and the
ability to provide a very high level of safety.
The ISO 11783 compliant PVED-CC has been specifically designed
for off-highway vehicles, from agriculture, construction and road
building, to materials handling, forestry and turf care.
Our PVED-CX actuator is also SIL 2 certified. This helps reduce
the time and cost associated with system qualification and
vehicle certification, required to meet the demands of Machinery
Directive 2006/42/EC and related safety standards.

PVG load-independent proportional valves enable our customers
to improve overall vehicle efficiency and save energy. While load-
sensing technology itself is not new, PVG valves can help meet
the demands of the Tier IV/Stage IV engine emissions regulations
by minimizing power losses in the hydraulic system.
ImproveHydraulicSystemEfficiency
Energy losses in a hydraulic system can be greatly reduced
depending on system design. For example, the difference in
efficiency between load-sensing and conventional hydraulic
systems can be seen in the four graphs below. By using PVG load-
sensing technology in combination with a variable displacement
pump, it’s possible to achieve a significant reduction in energy
loss. This increases overall vehicle efficiency and performance,
improves productivity and helps reduce total cost of ownership.
Additionalload-sensingbenefitsinclude:
Longer hydraulic component life, especially for pumps, •
due to reduced load
Faster and more accurate control, independent of load•
Often a reduced size of pump•
Smaller cooler or no cooler at all, due to reduced heat load•
Reduced noise levels as the hydraulic components are only •
subjected to the oil flow and pressure necessary in a given
load situation.

New Standards in Safety
A high level of safety has always been a priority when it comes
to PVG valves. Anticipating the demands of new safety legislation,
we have been developing products that help OEMs comply with
the requirements of the revised European Machinery Directive
(2006/42/EC) and related standards. These include our SIL 2
certified (Safety Integrity Level 2 according to IEC 61508) digital
actuator, PVED-CX, and oil supply cut-off module, PVSK.
SIL2CertifiedElectronicActuator
Based on proven PVE technology, PVED-CX operates using a self-
and neighbor-monitoring process, combined with the ability
to shut down all neighbor modules. Spool movement, internal
electronics, and software processes are monitored redundantly.
When using PVED-CX together with PVG valves and PVSK, oil flow
is controlled locally by the valve group. This shuts down work
function oil flow without influencing any other vehicle functions.
PVED-CX is also able to perform independent system monitoring
and diagnostics. This means that it does not require input from
a microcontroller in order to determine whether a system
malfunction has occurred. In the event of a signal loss or interruption,
oil flow is cut-off and the valve is brought to a safe state – fast.
NewSafetyRegulationsandRelatedStandards
European safety legislation has revised Machinery Directive 2006/42/EC and applies to all vehicles built in or shipped to Europe after December 29, 2009. This revision means that OEMs must perform and document a hazard and risk analysis for all vehicle functions.

Risk analysis must follow a functional safety standard, for example,
ISO 13849 or ISO 25119. The outcome of the analysis is a SIL rating
(Safety Integrity Level) or PL (Performance Level), which is used
to identify the minimum safety requirements for each vehicle
function.
Based on the derived SIL or PL, a system architecture (category)
is chosen for the safety function, and then verified. The challenge
for OEMs is to design and verify vehicle functions in order to meet
a specific SIL or PL identified by the hazard and risk analysis.
To help our customers meet this challenge, Sauer-Danfoss
is developing new products, in some cases pre-qualified, to help
comply with the new safety standards and European law.
We are working closely with our customers, to help speed up
system development and qualification, reduce total costs, and
bring vehicles to market faster.
