BENEFITS OF THE D671 TO D675 DIGITAL
SERVO-PROPORTIONAL VALVES
• Fieldbus data connection: Electrically separated fieldbus
interface.
• Diagnostic options: Integrated monitoring of the most
important environmental and internal parameters. Valve
parameters may be changed on site or remotely.
• Flexibility: Since parameters may be downloaded using
the fieldbus, the valve may be tuned during a machine
cycle and operating machine.
• Safety: Fail-safe options include a defined safe spool
position using a spring or using an external supply cut off
ensure operator safety.
FIELDBUS INTERFACE
The valves are parameterized, activated, and monitored via
the built-in fieldbus interface (e.g. CANopen, Profibus-DP or
EtherCAT). To reduce wiring, the fieldbus interface is provided
with two plugs. Thus, valves may be integrated into the bus
without any external T-joints. In addition, up to two
analog input commands and up to two analog actual value
o
utputs are available.
Optionally, the valve is available without a fieldbus interface.
In this case, the valve parameters are set using the integrated
service connector.
APPLICATION
In addition to flow control, the valves are capable of
controlling external axis signals such as position, speed, force
and similar parameters.
FLOW CONTROL (Q-CONTROL)
In this operating mode of the Servo-Proportional Valve, the
spool position is controlled. The applied command signal is
proportional to a particular spool position. The command
signal (spool position command) is fed to the valve
electronics. A position transducer (LVDT) measures the
spool's actual position and transfers this information to the
v
alve electronics. The electronics compare the actual spool
position and command signal, and control the linear force
motor or the ServoJet
®
Pilot Valve to position the spool as
required.
The position command can be controlled through parameters
in the valve software (i.e., linearization, ramping, deadband
or sectionally defined amplification).
DIGITAL ELECTRONICS
The digital control electronics are integrated into the valve.
The valve electronics contain a microprocessor system
performing all important functions via the valve software.

The ServoJet
®
Pilot Valve is based on the jet pipe design and
consists mainly of a torque motor, jet pipe and receiver.
An electric current through the coil (pos. 1)of the ServoJet
®
pilot
stage causes the armature (pos. 2) with the jet pipe (pos. 3) to
move. The deflected fluid jet, which is focused by a specially
shaped nozzle, hits one of the two receiver openings (pos. 8)
more than the other. This causes a pressure difference in the
p
ilot ports (pos. 5) of the ServoJet
®
P
ilot Valve. The resulting
flow moves the spool of the main stage in the corresponding
working direction. The return flow is via the annular space
(pos. 4) below the nozzle to the tank port (pos. 9).

The pilot valve consists of a linear force motor driven by a
permanent magnet, a driving rod connecting the armature
w
ith the spool and a spool in a bushing. The linear force
motor consists of a coil, permanent magnets, pole parts, an
armature and a centering spring. The 4-way spool controls
the flow from the pressure port to one of the two control
ports, simultaneously the flow from the other control port
to the tank port is controlled. The displacement of the
centering spring by moving the spool results in a return force
opposing the armature movement. An electric current in the
coil of the linear force motor gives rise to electromagnetic flux,
depending on the current direction, which superimposes the
permanent flux in the gaps between armature and pole parts.
Thereby a force is exerted on the armature which results in a
direction-dependent displacement, opposing the centering
spring. The spool is connected to the armature by a driving rod
and thus follows the displacements. Flow forces experienced
whenfluid is flowing throughthevalve as well as frictionforces
due to contamination between spool and bushing need to be
compensated by the linear force motor. The stroke of the spool
is approximately proportional to the coil current.

When returning to the center position, the spring force and
the drive force act in the same direction. In the center
position defined by the centering spring the linear force
motor does not consume any current.
Benefits of the Direct Drive Pilot Valve D633
• Low leakage losses: The Direct Drive Pilot Valve D633 does
not require a pilot flow when in the centered position. This
results in a significant reduction in energy consumption,
which is particularly important for machines with multiple
valves.
• High dynamics: The valve is highly dynamic due to the high
natural frequency of the Direct Drive Valve and pilot flows
close to those of two-stage pilot valves.
• High pressure efficiency: The very high pressure efficiency
even for small spool strokes makes the Direct Drive Pilot
Valve D633 a first choice for applications involving low control
pressures as it offers high control forces even for this type of
application: Secure position of the main spool is always
ensured.
• Reliability: The Direct Drive Pilot Valve D633 offers a high
degree of reliability due to the high actuation forces of the
linear force motor as compared to proportional magnets.

VALVE FLOW CALCULATIONS
FLOW CHART (4-WAY FUNCTION)
The actual valve flow is dependent on the spool and the
pressure drop Δp across the lands. At 100 % command signal
the valve flow at rated pressure drop Δp
N
= 5 bar (75 psi) per
land is the rated flow Q
N
. For other than rated pressure drop,
the valve flow changes at a constant command signal
according to the following formula.
The actual valve flow Q must not exceed a mean velocity of
30 m/s in the ports P, A, B and T.
The maximum flow rates given in the flow diagrams should
not be exceeded to prevent the risk of cavitation.
p
P
= Pressure at the P-port of the valve (supply pressure)
Note: The pilot pressure range (see technical data) must be

bserved.
DESIGN SPECIFICATIONS

GENERAL
For applications with servo-proportional valves where certain
safety regulations are enforced to prevent dangers to
o
perator and the machine, a "safe spool position" is needed
in order to avoid potential damage. Therefore, a fail-safe
version is offered as an option for the multi-stage
servo-proportional valves. After switching off the 24 V
supply of the safety solenoid valve, this fail-safe function
causes a defined spool position: Overlapped center position
or open position A T or B T.
For fail-safe valves in series D671 to D675, movement to the
safe central position is ensured by hydraulically connecting
the two control volumes of the main stage using a 2/2- or a
4/2-way valve, respectively. The return force of the centering
springs moves the spool into the fail-safe position.
With fail-safe valves, it is possible to check whether the main
spool is in a safe position. If the spool is within the defined
s
afe range, pin 11 shows a signal with a voltage exceeding
8.5 V. If the voltage is lower than 6.5 V, the spool is not in a
safe position.
T
o reduce the fail-safe switching time, it is advised to both
switch off the supply of the 2/2- or 4/2-way valve and the
enable signal at the same time.
NOTE:
According to ISO 13849 a higher safety category can be
achievedby using a fail-safe valve with spool position
monitoring. For this, attention should be paid to appropriate
machine safety standards.

The valve series D671 to D675 is offered with various fail-safe
functions. The behavior of the valve in a fail-safe situation
depends on the fail-safe function selected, the pilot valve
and the actual pilot pressure, electrical supply of the valve

GENERAL REQUIREMENTS FOR VALVE ELECTRONICS
• All signal lines, including those of external transducers,
should be shielded.
• Shielding should be connected radially to ⊥ (0 V), power
supply side, and connected to the mating connector
housing (EMC).
• Minimum cross sectional area of all lines ≥ 0.25 mm
2
(0.01 in
2
)
• Consider voltage losses between cabinet and valve.
See also Moog technical note TN 494 (see section
"Accessories and Documents for all Sizes").
• Note: When making electrical connections to the valve
(shield(댷)) appropriate measures must be taken to ensure
that locally different ground electical potentials do not
result in excessive ground currents. See Moog technical
note TN 353 (see section "Accessories and Documents for
all Sizes").
• All connected circuits have to be separated from the
network using a "safe disconnect" device according to
EN 61558-1 and EN 61558-2-6. All voltages have to be low
voltage type according to EN 60204-1. We recommend the
use of SELV/PELV power supplies.

HYDRAULICS WITH FIELDBUS
GENERAL
Modern automation technology is characterized by an
increasing decentralization of processing functions using
serial data communication systems. The use of serial bus
systems instead of conventional communication technology
ensures the increased flexibility of systems in terms of
modifications and expansions.
It also has a significant potential for savings in project and
installation costs in many areas of industrial automation.
Amongst the benefits that have become viable through the
u
se of fieldbuses are additional options for parameterization,
enhanced diagnosis options and the reduction of variants.
VDMA PROFILE
In one working group within the German Machinery and
industrial equipment Manufacturers Association (VDMA),
a profile was created in collaboration with numerous
well-known hydraulic system manufacturers:
This profile describes communication between hydraulic
components via a fieldbus. It defines uniform functions and
parameters in a standardized exchange format.
CANopen
According to EN 50325-4
CAN bus was originally developed for use in automobiles,
but has been used in mechanical engineering in a variety of
applications for many years.
The CAN bus is primarily designed for transmission security
and speed.
CAN bus features:
• Multi-master system: Each participant can transmit and
receive
• Topology: Linear structure with short stub line
• Network extension and bandwidths:
- Up to 25 m (80.4 ft) at 1 Mbit/s
- Up to 5000 m (16090 ft) at 25 kbit/s
• Addressing type: Message-oriented via identifier;
priority assignment of the message via identifier
• Safety: Hamming distance = 6, i.e. up to 6 individual
errors/message are recognized
• Bus physics: ISO 11898
• Maximum number of participants: 110 (64 without a
repeater)
PROFIBUS-DP
According to EN 61158
Profibus-DP has been developed for the process and
production industries and therefore is being supported
by many control system manufacturers.
Profibus-DP features:
• Multi-master system: Several masters share access time and
initiate communication
Slaves only react to requests
• Topology: Linear structure with short stub line
• Network extension and bandwidths:
- Up to 100 m (321.8 ft) at 12 Mbit/s
- Up to 1200 m (3861.6 ft) at 9.6 kbit/s per segment
Repeaters may be used
• Addressing type: Address oriented
• Priority/cycle time assignment of messages by master
configuration
• Bus physics: RS-485 according to EIA-485
• Maximum number of participants: 126 (32 without a
repeater)
ETHERCAT
According to IEC/PAS 62407
EtherCAT has been developed as an industry bus based on
Ethernet to meet increasing demands regarding cycle time.
EtherCAT bus is designed for high data transmission rates
and fast cycle times.
EtherCAT bus features:
• Single master system: The master triggers communication
Slaves only react to requests
• Topology: Line, star, tree and ring structure following the
daisy chain principle
• Network extension and bandwidths: 100 m (321.8 ft)
between participants, 100 MBit/s
• Addressing type: Address oriented, one datagram for all
participants
• Bus physics: Fast Ethernet 100 Base Tx
• Maximum number of participants: 65535
