General The PDV technology platform, is the latest step in proportional directional
valves con guration.
It takes mobile machine control to next level of performance, reliability, and
feature stringent technical demands, exacting quality standard, and safety
regulations.
Based on load sensing technology, are new breakthrough products with
up-grated hydraulic functions that ful l the ever increasing market
demands for improved machines productivity, safety requirements, energy
e cient and environmental operations.
They provides also a wide choice of control options, and are meant to be
used in hazardous area also, according to Atex 2014/34/UE Directive and
IECEx protocol.
Safety Conformity assessment
FMEA and FMEDA, ( failure modes e ects and diagnostic analysis ), are sy-
stematic analysis technique applied in early phases of a given system deve-
lopment, in order to detect weak points early.
When it comes to more complex products and assemblies involving a combi-
nation of both electrical and hydraulic parts, the need to ensure that adegua-
te surveillance over the design and manufacturing of key parts is paramount,
to be compliance with the on-going series Standards IEC 61508.
Evaluation of the achieved performance level PL and relationship
with SIL
Parts of machinery control systems that are assigned to provide safety fun-
ctions are called safety-related parts of control systems and these can consist
in hydraulic valves with hardware and software, and can either be separate
from the machine control system or an integral part of it.
PDV units, can be requested to be applied as “logic units to ensure safety
functions in accordance with Machine Directive EN 13849 “.
For the purpose of this part of Machine Directive, the ability of safety- related
parts to perform a safety function is expressed through the determination of
the performance level.
To make the assessment of the quanti able aspects of the PL easier, this part
of EN 13849 provides a simpli ed method based on the de nition of ve de-
signated architectures that ful l speci c design criteria and behaviour under
a fault condition.
Therefore, the machine builder or system integrator have full accountability
for making the nal products selection and assuring that all performance,
safety and warning requirements of the application are being met.

which in
turn feeds the down-stream working sections.
The PDS spool neutral position

unload the LS pump signal to tank, so that the swashplate angle is towards the minimum
displacement and pressure in stand-by setting.
The spool position determines the ow demands ( speed rotation ) of the two HPM motors

.
The PDS main spool compares the pressure drop before and after the spool notches ( di erential pressure ∆p ), and therefore,
the pump ow remain constant.
If the di erential pressure increase, the pump swashplate is swivelled back towards the minimum displacement, and if the dif-
ferential pressure decrease, the swashplate angle increase towards the max ow displacement until balance is restored within
the valve.
Actuators load determines the working pressure, and the built-in pressure compensator

enable simultaneously function
regardless of di erent working pressure.

On this con guration, the level of safety degrees for the complete

The e ect of this condition is a complete and safely pressureless

the pressure into the system will be reduced to the sum of the
tank port pressure, plus the pressure drop through the poppet
unloading valve (see characteristic curve below)
When the inlet section comes with this con guration and the
pump unloading system is connected with the active fault
monitoring spool actuators, the level of safety degree protec-

Designed to be con gured either as open centre ( xed displa-

Inlet comes standard with pressure compensated 3-way ow
regulator
1
, that when pump is started and working sections
spools are in neutral position, it’s unloaded to tank, and the oil
ow being supplied from the pump, passes through the 3-way
ow regulator to tank with minimal o -load pressure drop (see

If the working pressure reaches the setting of the upstream max
pressure pilot relief valve
3
, the 3-way ow regulator will be
opened to tank, thus limiting the working pressure inside the
complete PDV.
By acting clockwise on the pilot shifting spool
4
, without chan-
ging any components, the inlet section circuit will be transformed
into closed centre con guration.
In this con guration the load sensing pilot pressure is led to pump
control via the LS connection. When a main spool is actuated,
the pump regulator will adjust the displacement so that the set
di erential pressure ( stand-by pressure ) between P and LS signal
is maintened.
The pressure relief valve 3 is to be set at 35 bar above maximum
cut-o pressure set on the pump.
The LS control performs as a constant pressure control also, decre-
asing pump displacement when system pressure reaches the PC
setting.
The pressure compensating function has the priority over the load
sensing function.

Designed for use with LS variable displacement pumps.
This version of inlet comes standard with a double stage cut-o
pump system
1
, that when activated according to an electrical
signal
2
, all down-stream working section will be perfectly and
safely sealed from pressure and ow, protecting the complete
hydraulic machines control against the negative e ect of the re-
maining stand by pressure.
Inlet comes standard without pressure compensated 3-way ow
regulator.
When pump is started and PDV spools are in neutral position, the
LS pump signal is unloaded to tank.
When one or more of the spools are actuated, the highest signal
is sent to the pump regulator that control the pump swashplate
angle.
The PDS main spool compares the pressure drop before and after
the spool notches (di erential pressure ∆p), and therefore, the
pump ow remain constant.
The position of the PDS spool determines the ow demand. If the
di erential pressure increase, the pump swashplate is swivelled
back towards the minimum displacement, and if the di erential
pressure decrease, the swashplate angle increase towards the max
ow displacement until balance is restored within the valve.
The inlet section can comes with an optional pressure relief valve
3
that should be set at pressure about 35 bar above maximum
system pressure set on the pump regulator.
The built in pressure reducing valve
4
, act as the pilot pressure
supply for the electrical actuators, as well as, the hydraulic remote
controls.
When the inlet section comes with this con guration and the
cut-o pump system is connected with the active fault moni-
toring spool actuators, the level of safety degree protection
for the complete hydraulic system becomes very high, opera-
tor free, and helps OEM to meet the PL ( Performance Level )
required to be comply with the safety demands of Machinery
Directive 2006/42/EC.

Designed for use with LS variable displacement pumps.
PDIM is a MID inlet section that allows the PDV74 to be supplied
with a larger variable pump ow capacity with a lower pressure
drop.
PDIM enable to PDW to be mounted on both sides of the pump
side module, therefore, the PDW tted on PMID left side, the A-B
work port position are reversed.
Inlet comes standard without pressure compensated 3-way ow
regulator.
When pump is started and PDV spools are in neutral position, the
LS pump signal is unloaded to tank.
When one or more of the spools are actuated, the highest signal
is sent to the pump regulator that control the pump swashplate
angle.
The PDS main spool compares the pressure drop before and after
the spool notches (di erential pressure ∆p), and therefore, the
pump ow remain constant.
The position of the PDS spool determines the ow demand. If the
di erential pressure increase, the pump swashplate is swivelled
back towards the minimum displacement, and if the di erential
pressure decrease, the swashplate angle increase towards the max
ow displacement until balance is restored within the valve.
The inlet section may comes with an optional pressure relief valve
that should be set at pressure about 35 bar above maximum
system pressure set on the pump regulator.
According to an electrical signal coming from the remote controls
or I/O controller, the PIU solenoid unloading valve enable the LS
signal to be relieved to tank.
The e ect of this con guration is an almost pressureless system,
where the activated actuators will be automatically catted o ,
and the pressure in the system will be reduced to the sum of the
tank port pressure, plus the di erential pressure of the pump,
therefore, care must be given, because all the actuators whose
working pressure is lower than the remaining pressure might be
still operated.
Also with the use of PIU emergency solenoid unloading valve, the
level of safety degrees for the complete PDV valve is quite low,
therefore, operator’s great supervision is required.

PIY module
This inlet con guration ( for open or closed centre ) is suited to supply the PDV74 with a ow from an auxiliary manual opera-
ted emergency pump.
Normally the main pump supply the built in pressure reducing valve through the PIY, screw-in cartridge.
In case of main pump failure, the external shuttle valve ensure that the main pressure reducing valve is being supplied from
the emergency hand pump, and the pilot oil supply available for electric actuators.

Oil ow characteristics
With ow control spool, the oil ow depends on type of PDW module ( with or without pressure compensator ) and type of
pump ( xed or variable displacement ).

By using proportional directional valves along with overcenter valves, instability problems may occurs in the form of pressure
surging.
To suite this problems, spools with di erent circuit named “ Pressure Control “ have been developed.
The main purpose of these spools, is to hold in position the 2-way pressure compensator, preventing it from going into unsta-
ble condition, and in turn, to keep the overcenter’s pilot pressure value as stable as possible.
Pressure control spools, must always be used with pressure compensated working sections equipped with pilot LS A/B relief
valves.
Pressure control spool, normally give a higher degree of stability to whole hydraulic system, however, we advise to look after
their use, because:
● The valve may loose a bit of pressure compensation, becoming load dependent.
● The pump pressure may be considerably higher than that necessary to move the load.

Technical features
PWS-PWA
PWR
PWS, PWA and PWB are shock suction valves design
to absorb shock e ects only, and they should never
be used as a pressure relief valves.
PWS, PWA and PWB are set at an oil ow of 10 l/min.
If the hydraulic actuator requires a pressure relief
valve function, a PDW module with built-in LS A/B pilot
pressure limit valves should be used

PDLD module - Electrical LSA/B unloading
Proportional actuation normally open (current signal mA)
PDLD is an electro-hydraulic device that allows
the A/B port working pressure to be remotely an
proportionally operated according to a current
signal (mA). When the working pressure exceed
the setting pressure value, the A/B port oil ow
will be cutted o .
When PDLD is not energized, PDW is almost pres-
sureless, as well as the A-B oil ow is cutted o .

PEAC111 is a proportional high performance PDV spool actuation
with integrated electronics and inductive transducer ( LVDT ) that
operates safely and precisely the main spool movement according
to an electrical signal coming from a remote control.
The input signal by means of the PCB and the two proportional
pressure reducing valves, determines the level of the pilot pressu-
re which moves the main spool.
The spool position is detected in the LVDT transducer which gene-
rates an electric feed-back signal registered by the electronics.
The variation between the input signal and the feed-back signal,
actuates the solenoid valves accordingly, so that, the hydraulic
pilot pressure will drive the main spool in the right position.
All PEAC111 modules comes with integrated fault monitoring
system, available in two version:
Active version
Passive version
Active fault monitoring
When an error state is detected, the two proportional solenoid
valves will be automatically deactivated, a red lamp will light-up
and drive the spool in neutral position (if it’s not seized up ).
The system will only react to failures of more than 500 ms ( in
other words there is delay of half a second before anything
happens ). An alarm signal is sent out through the connector, and
minus is opened.
This error state is memorized, and continues until the system is
being reset by switching o the supply voltage.
Shortly, when the active fault monitoring system is connected
and an error state is detected, the system ensures a fast and
operator free reaction, that will put the complete hydraulic circuit
into venting conditions, thus preventing uncontrollable machine
movements.
Passive fault monitoring
When an error state is detected, the two proportional solenoid
valves will not be deactivated, a red lamp will light-up, but still
control the main spool.
When a fault condition occurs, after a delay of 250 ms an alarm
signal is sent out through a devoted pin
This state is not memorized, and when the faulty state disappears,
the alarm signal will turn to passive again.
In order to prevent the electronic from going into an unde ned
state, any time the system is being triggered or reset, a general
check of power supply and the internal clock frequency is made.
The use of PEAC111 module both passive or active version, allows
the machines hydraulic system to be made with di erent level of
safety degree that for the choice of which it is essential to know
the exactly required functions.
When the PEAC111 module active version is connected with
the pump unloading system, the level of safety degree pro-
tection for the complete hydraulic system becomes very high,
operator free, and helps OEM to meet the PL ( Performance
Level ) required to be comply with the safety demands of Ma-
chinery Directive 2006/42/EC.

PEAC112 is a proportional high performance PDV spool actuation
with integrated electronics and inductive transducer ( LVDT ) that
operates safely and precisely the main spool movement according
to an electrical signal coming from a remote control.
The input signal by means of the PCB and the two proportional
pressure reducing valves, determines the level of the pilot pressu-
re which moves the main spool.
The spool position is detected in the LVDT transducer which gene-
rates an electric feed-back signal registered by the electronics.
The variation between the input signal and the feed-back signal,
actuates the solenoid valves accordingly, so that, the hydraulic
pilot pressure will drive the main spool in the right position.
All PEAC112 modules comes with integrated fault monitoring
system, available in two version:
Active version
Passive version
Active fault monitoring
When an error state is detected, the two proportional solenoid
valves will be automatically deactivated, a red lamp will light-up
and drive the spool in neutral position (if it’s not seized up ).
The system will only react to failures of more than 500 ms ( in
other words there is delay of half a second before anything
happens ). An alarm signal is sent out through the connector, and
minus is opened.
This error state is memorized, and continues until the system is
being reset by switching o the supply voltage.
Shortly, when the active fault monitoring system is connected
and an error state is detected, the system ensures a fast and
operator free reaction, that will put the complete hydraulic circuit
into venting conditions, thus preventing uncontrollable machine
movements.
Passive fault monitoring
When an error state is detected, the two proportional solenoid
valves will not be deactivated, a red lamp will light-up, but still
control the main spool.
When a fault condition occurs, after a delay of 250 ms an alarm
signal is sent out through a devoted pin
This state is not memorized, and when the faulty state disappears,
the alarm signal will turn to passive again.
In order to prevent the electronic from going into an unde ned
state, any time the system is being triggered or reset, a general
check of power supply and the internal clock frequency is made.
The use of PEAC112 module both passive or active version, allows
the machines hydraulic system to be made with di erent level of
safety degree that for the choice of which it is essential to know
the exactly required functions.
When the PEAC112 module active version is connected with
the pump unloading system, the level of safety degree pro-
tection for the complete hydraulic system becomes very high,
operator free, and helps OEM to meet the PL ( Performance
Level ) required to be comply with the safety demands of Ma-
chinery Directive 2006/42/EC.

PEAC011 is a proportional open loop spool actuation with
integrated electronics that operates the main spool movement
according to an electrical signal coming from a remote control.
The input signal by means of the PCB and the two proportional
pressure reducing valves, determines the level of the pilot pressu-
re which moves the main spool.
PEAC011 does not have neither the transducer spool position
control nor fault monitoring system, this means that any forces
which override the pilot pressure spool forces, may chenge the
spool position with no error signal, and the safety of the whole
system is left to the operator’s visual control, only.
PEAC011 is recommended where a simple proportional control
is required, and where hysteresis and reaction time are not so
critical.
