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.

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 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.
