ISO cylinder family, P1D
A completely new cylinder range from the ground up, with
major investment in research, material and technology,
demands long experience and major resources. When we
developed our P1D cylinder range, we started from
scratch, but not really. Decades of research and learning
about what our customers really need world-wide has
given us a very stable foundation to start from.
P1D is a cylinder design of the highest possible quality,
every detail has been thought through, without making any
compromises. It has a large number of innovations which
could only be achieved by using the best possible
materials and methods. The result is a complete family of
ISO/VDMA cylinders, of which we are very proud.
P1D is a high technology cylinder design for just about
every conceivable application, both simple and highly
complex.
The same high technology platform is used for three main
versions:
•P1D Standard – the universal, general purpose
cylinder with high performance and long life.
•P1D Clean – the new product level for ISO/VDMA
cylinders of clean design with a system of integrated,
adjustable sensors (patent applied for), for stringent
hygiene demands.
•P1D Flexible Porting – the innovative design which
saves space and reduces dimensions by allowing
connections to be made in the front or rear end of the
cylinder.
Let us present Series P1D more in detail in the following
pages.

P1D Standard
The innovative P1D is a future-proof generation of ISO/
VDMA cylinders. The cylinders are double-acting, with a
new design of air cushioning. The light, stiff body extrusion
has sensor grooves for simple and protected sensor
installation.
Installation dimensions according to international
standards
The new P1D complies with the current ISO 6431,
ISO 15552, VDMA 24562 and AFNOR installation
dimension standards. For customer reassurance world-
wide.
High technology design
The best materials, manufacturing methods and design of
every detail have been carefully tested, to give the best
possible product. The internal components are made of
high strength plastics, for quiet operation and long service
life. The aluminium end caps and the torsionally stiff
aluminium body extrusion make the cylinder robust and
suitable for a wide range of applications.
High quality
The P1D has been developed with quality in all phases –
requirement specification, design, planning, purchasing,
production, distribution and service. We have been
certified under the ISO 9001 QA standard for the past ten
years. Quality in all our products and services is our
watchword.
Even more functions and variants
The P1D is available with all the usual optional designs,
such as: Through piston rod, high and low temperature,
hydraulic operation, extended piston rod etc.
A new special variant is the unique self-lubricating
HDPE scraper ring and piston rod seal, specially
designed for operation with a completely dry piston rod
(i.e. applications where the film of grease on the piston rod
is regularly washed off).
Surface treated steel
end cover nuts for
tough environments.
Sealing plugs are
available for all P1D
cylinders.
All seals are made from
polyurethane, which
gives P1D cylinders
extra long service life.
P1D Standard has a
further development
of our famous body
extrusion with
grooves for the new
”drop-in” sensors.
The cylinder end covers
do not have any cavities
or pockets which could
collect water or dirt. This
facilitates effective
cleaning.
The body extrusion is
anodised inside and
outside, for long life
and low friction.
The cylinders have
magnetic pistons
as standard.
Polyurethane end-
of-stroke washers
give smooth and
quiet operation.
One piston rod
nut according
to ISO 439B is
included as
standard.
P1D has a stainless steel
piston rod as standard.
Hard chromed steel, hard
chromed stainless steel
and acid-proof steel are
available as options.
All P1D cylinders for
normal temperature
have initial greasing of a
transparent, non-toxic
grease, approved by
the food industry, which
is entirely free from
PTFE and silicone.
The cushioning has
individual flow geometry
for each cylinder size.
This gives effective
cushioning which is
easier to set and adjust.

Complete accessory programme
P1D offers a complete ISO, VDMA and AFNOR
compatible accessory programme, with a wide range of
piston rod and cylinder mountings for both pivoted and
fixed operation. Several of these types of mountings are
available in stainless steel. The new ”drop-in” sensors are
available with both reed and electronic operation, with a
wide choice of connector types and cable lengths.
New, mechanically protected sensor technology
The body extrusion has recessed sensor grooves on three
sides of the cylinder. The new sensors are of the ”drop-in”
type, and are quickly and easily installed in the T-groove
from the side. Both the cable and the sensor are protected
in the groove. Choose a sensor with 3 or 10 m cable,
8 mm connector or the new M12 connector.
Optimised cushioning
Thanks to the plastic inserts in the end covers, each
cylinder bore has been given individual flow geometry.
This provides optimised cushioning, which is quicker and
easier to set and adjust.
Smooth, quiet operation and long service life
All seals and end-of-stroke washers are made from
polyurethane (PUR), the bearings and piston are made
from proven engineering plastics with excellent bearing
properties and all cylinders are greased at the factory with
a transparent, foodstuffs-approved grease. Altogether this
gives the P1D very long service life and smooth, quiet
operation.

P1D Clean
P1D Clean is a new version in our ISO cylinder system,
completely designed for the foodstuffs industry. Many
years’ experience of the stringent requirements for
hygiene, choice of material and corrosion resistance, from
a wide spectrum of foodstuffs applications have guided
the development of this cylinder version. Great emphasis
has been put on the external design of the cylinder, choice
of materials and corrosion protection.
Main dimensions according to international standards
All the main dimensions of the P1D Clean comply with ISO
6431, ISO 15552, VDMA 24562 and AFNOR standards.
The exception is the somewhat larger footprint of the end
covers and envelope of the body extrusion, due to the so-
called positive geometry (hygienic, convex, easy-to-clean
geometry) of the cushioning adjustment screw and the
components in the integrated sensor system.
Common, high technology design platform
The P1D Clean has the same technical platform as the
P1D Standard. The best materials, including the
polyurethane (PUR) seals, manufacturing methods and
the careful attention to detail design give the P1D Clean
smooth, quiet operation and long service life.
Convex shape for optimum hygiene
P1D Clean has a convex body extrusion, which makes the
cylinders easy to keep clean. Irrespective of installation
position, fluids run off the body extrusion surfaces.

Cushioning screw with positive geometry
To offer the best hygiene properties, the projecting
cushioning screw, is sealed with rubber seal against the
end cover. This eliminates dirt-collecting cavities and
gives the best hygiene, since it is so easy to clean.
Sealing plugs
Four plastic sealing plugs are supplied with every
P1D Clean cylinder. These are installed in the end cover
screws which are not used for the cylinder installation. To
ensure the sealing function, the plugs can be used only
once i.e. they can not be re-used. When installed in the
end cover screws, they should be tapped lightly with a
hammer to securely fix.
Patent applied system for integrated standard sensors
The P1D Clean cylinder has a system of sensors, which
are fully integrated into the body extrusion, to give the
cylinders a clean external design. Up to four sensors
chosen from the range of P1D standard sensors, reed or
electronic operation, can be mounted in two dedicated
grooves beneath a transparent, sealed moulding.
Tightening the stop screw onto the cam shaft, will lock
each sensor in the desired position, with great force. The
sensor LEDs are always fully visible, which facilitates
commissioning, adjustment and trouble-shooting. The
entire sensor system has a hose-proof design, equivalent
to IP65. P1D Clean can be ordered with factory-fitted
sensors in the end positions, which can then easily be
moved to any other position along the entire stroke.
Up to four integral sensors
Cylinders for two integral sensors have two undivided
camshafts along the entire stroke. Free choice of cable
exit, front or rear. There is also a version with divided
camshafts for up to four sensors, which are installed two
from each end cover, with cable exit front and rear.
The sensor position is easily adjusted by
undoing a set screw and using the cable to
move the sensor to the desired position.
The sensors are mounted into their grooves
through the opening in a transparent, sealed
cover. The sensor cables have strain relief and
are sealed.
Once the sensor has been locked in its new
position, the protective cover is installed
again.
Simple sensor adjustment

P1D Flexible Porting
Progress leads to smaller components and machinery. In
harmony with this trend, and complying with the main
dimension requirements in ISO 6431, we have developed
P1D Flexible Porting, which offers new, smarter design
solutions. Since one end of the cylinder can be placed in
restricted, unused spaces, without needing any
connections, the space in the application can be used
more efficiently, or made more compact.
Main dimensions according to international standards
Apart from the projecting connections on sizes Ø32–63 mm
P1D Flexible Porting complies with ISO 6431, ISO 15552,
VDMA 24562 and AFNOR standards.
Common, high technology design platform
P1D Flexible Porting has the same high technology level
as P1D Standard and P1D Clean. The future-proof design
gives P1D Flexible Porting high performance and long
service life.
Body extrusion with integrated air channels
P1D Flexible Porting has the same body extrusion as the
P1D Clean cylinder. Since the air is led through channels
built into the body extrusion, both connections can be
made to either end of the cylinder. The flow capacity of the
air channels is big enough not to restrict the cylinder
speed in all normal applications.

Straight or elbow push-in fittings for Ø32-63 mm
For cylinder bore Ø32-63 mm, one connection is located
on the body extrusion. The connector from the Moduflex
valve range is used for this connection. A matching
Prestolok 2 (plastic) fitting is used for the connection at the
end cover. Choose between straight or elbow fittings. The
other end has a plug installed in the unused cylinder port.
Threaded connections for Ø80-125 mm
Cylinder bore Ø80-125 mm have two threaded
connections located in either end cover. The other end
has plugs in the cylinder ports. These plugs can be
moved to the other end to suit the application.
Mechanically protected ”drop-in” sensors
The body extrusion, which is common to all P1D Clean
and P1D Flexible Porting cylinders, has recessed sensor
grooves in the side opening. The geometry has at the
same time been designed for ”normal” mechanical sensor
installation (similar to P1D Standard) and for the built-in
sensor system (P1D Clean). Use standard sensors in the
usual way.
Combine with P1D Clean
For compact applications with stringent hygiene
requirements, P1D Clean can be combined with Flexible
Porting. This cylinder version complies with many different
requirements and offers new opportunities for creating
effective application solutions.

P1DTie-Rod
The P1D is available in a tie-rod version, based on the
same high level technology. This future-proof cylinder is
the perfect choice wherever a tie-rod cylinder is needed.
Installation dimensions to international standard
The P1D Tie-Rod complies with ISO 6431, ISO 15552,
VDMA 24562 and AFNOR installation dimension
standards. For customer reassurance world-wide.
Smooth, quiet operation and long service life
All seals and end-of-stroke washers are made from
polyurethane (PUR), the bearings and piston are made
from proven engineering plastics with excellent bearing
properties and the initial greasing at the factory with a
transparent, foodstuffs-approved grease. Altogether this
gives the P1D very long service life and gentle, quiet
operation.
Optimised cushioning
Thanks to the plastic inserts in the end covers, each
cylinder bore has been given an individual flow geometry.
This gives an optimised cushioning, which is quicker and
easier to set and adjust.
Complete accessory programme
P1D offers a complete ISO, VDMA and AFNOR
compatible accessory programme, with a wide range of
piston rod and cylinder mountings for both pivoted and
fixed operation.
”Drop-in” sensor
The P1D Tie-Rod uses ”drop-in” P1D sensors. An
ingenious multi-jointed adapter fixes the sensors in any
chosen position along the stroke.

Using P1D cylinders as a platform, a number of different designs
can be produced to suit differing requirements. Please refer to
the order key on pages 24 - 25 for the designation of each
variant.
P1D complete working unit
P1D Standard can be ordered with a factory-fitted valve and
piping. The valve series is the robust and compact Viking series.
Of course, the entire range of P1D accessories can also be used
for the P1D with built-in valve, and cylinders can be ordered with
factory-fitted accessories and sensors.
For more information, see page 41.
P1D cylinder with piston rod locking
The P1D cylinder is available in a version with piston rod locking,
allowing the piston rod to be locked in any position. The lock
unit, of the air/spring actuated type, is integrated in the front end
piece of the cylinder. The lock unit can be used for braking as
well as locking. With no signal pressure, the full force of the lock
is applied to the piston rod, and the lock is released at 4 bar
signal pressure. Lock units are available for P1D Standard
(P1D-L) and P1D Clean (P1D-D) in dimensions Ø32-125 mm.
P1D Standard can be ordered with a lock unit and a built-in
valve (P1D-4).
For more information, see page 44
Alternative piston rod materials
All P1D cylinders in all bores, Ø32-125 mm, can be ordered with
the following piston rod materials:
– Steel, hard chromed
– Stainless steel, roller polished (standard)
– Acid-proof steel, roller polished
– Stainless steel, hard chromed
Through piston rod
All P1D cylinders in all bores, Ø32-125 mm, are available with a
through rod. Cylinders with a through rod can take higher side
forces thanks to the double support for the piston rod. In
addition, this design makes it easier to install external position
sensors.

Design variants for P1D Standard, P1D Clean, P1D Flexible porting and P1D Tie-Rod
Operation with dry piston rod
In many applications, primarily in the foodstuffs industry, the
cylinders are cleaned frequently. This means that the film of
grease on the piston rod is washed off, which puts special
demands on the materials and the design of the piston rod seal
system (scraper ring and piston rod seal). A piston rod seal
system specially designed for dry rod operation is available as
options for this type of application, for all bores of P1D cylinders.
The system has a specially designed L-shaped seal and the
material is self-lubricating, high molecular weight plastics
(HDPE) – the same system as in our previous P1C cylinders,
with proven function.
Low and high ambient temperature
For all bores, Ø32-125 mm, the P1D can be supplied in special
high ambient temperature and low ambient temperature
versions. The cylinders have seal systems, materials and grease
for their particular temperature ranges. The high temperature
version does not have magnetic piston (no function at high
temperatures). The low temperature cylinders do have magnetic
piston, but remember that most sensors are specified to – 25 °C
(no function below this temperature). Ambient temperature
ranges:
– Low temperature: -40 °C to +40 °C
– High temperature: -10 °C to +150 °C, peaks up to +200 °C
Low pressure hydraulics
The P1D in bores Ø32 - 125 mm can be supplied with special
seals for operation with low pressure hydraulics up to 10 bar.
Temperature range -20 °C to +80°C.
3 and 4 position cylinders
By installing two cylinders with the same or different stroke, it is
possible to build a working unit with three or four positions. This
type of unit is available as factory-fitted P1D tie-rod cylinders
(P1D-T) in all bores, Ø32-125 mm. Other P1D cylinders can be
flange mounted back-to-back with a special mounting
(see pages 49 and 56).
Tandem version
The P1D is also available as a tandem cylinder, i.e. two cylinders
connected in series. This cylinder unit has almost twice the
force, which is a great advantage in restricted spaces. Tandem
cylinders are available as tie-rod cylinders, P1D-T, in all bores
Ø32-125 mm.

Cushioning characteristics
The diagram below is used for dimensioning of cylinders related
to the cushioning capacity. The maximum cushioning capacity
shown in the diagram assumes the following:
• Low load, i.e. low pressure drop across the piston
• Equilibrium speed
• Correctly adjusted cushioning screw
• 6 bar at cylinder port
The load is the sum of internal and external friction, plus any
gravitational forces. At high relative load (pressure drop
exceeding 1 bar), we recommend that for any given speed, the
mass should be reduced by a factor of 2.5, or for a given mass,
the speed should be reduced by a factor of 1.5. This is in relation
to the maximum performance given in the diagram

Guide for selecting suitable tubing
The selection of the correct size of tubing is often based on
experience, with no great thought to optimizing energy efficiency
and cylinder velocity. This is usually acceptable, but making a
rough calculation can result in worthwhile economic gains.
The following is the basic principle:
1. The primary line to the working valve could be over sized (this
does not cause any extra air consumption and consequently
does not create any extra costs in operation).
2. The tubes between the valve and the cylinder should,
however, be optimized according to the principle that an
insufficient bore throttles the flow and thus limits the cylinder
speed, while an oversized pipe creates a dead volume which
increases the air consumption and filling time.
The chart below is intended to help when selecting the correct
size of tube to use between the valve and the cylinder.
The following prerequisites apply:
The cylinder load should be about 50% of the theoretical force
(= normal load). A lower load gives a higher velocity and vice
versa. The tube size is selected as a function of the
cylinder
bore
, the desired cylinder velocity and the tube length between
the valve and the cylinder.
If you want to use the capacity of the valve to its maximum,
and obtain maximum speed, the tubing should be chosen so
that they at least correspond with the equivalent restriction
diameter (see description below), so that the tubing does not
restrict the total flow. This means that a short tubing must have at
least the equivalent restriction diameter. If the tubing is longer,
choose it from the table below. Straight fittings should be chosen
for highest flow rates. (Elbow and banjo fittings cause
restriction.)
1) The “equivalent throttling bore“ is a long throttle (for example a tube) or a series of throttles (for example, through a valve)
converted to a short throttle which gives a corresponding flow rate. This should not be confused with the “orifice“ which is
sometimes specified for valves. The value for the orifice does not normally take account of the fact that the valve contains a
number of throttles.
2) Qn is a measure of the valve flow capacity, with flow measured in litre per minute (l/min) at 6 bar(e) supply pressure and 1 bar
pressure drop across the valve.

Example 1 : Which tube diameter should be used?
A 50 mm bore cylinder is to be operated at 0.5 m/s. The tube
length between the valve and cylinder is 2 m. In the diagram we
follow the line from 50 mm bore to 0.5 m/s and get an “equivalent
throttling bore“ of approximately 4 mm. We continue out to the
right in the chart and intersect the line for a 2 m tube between
the curves for 4 mm (6/4 tube) and 6 mm(8/6 tube). This means
that a 6/4 tube throttles the velocity somewhat, while an 8/6 tube
is a little too large. We select the 8/6 tube to obtain full cylinder
velocity.
Example 2 : What cylinder velocity will be obtained?
A 80 mm bore cylinder will be used, connected by 8 m 12/10
tube to a P2L-B valve. What cylinder velocity will we get? We
refer to the diagram and follow the line from 8 mm tube length up
to the curve for 12/10 tube. From there, we go horizontally to the
curve for the Ø80 cylinder. We find that the velocity will be about
0.5 m/s.
Example 3 : What is the minimum inner diameter and
maximum lenght of tube?
For a application a 125 mm bore cylinder will be used. Maximum
velocity of piston rod is 0.5 m/s. The cylinder will be controlled by
a P2L-D valve. What diameter of tube can be used and what is
maximum lenght of tube.
We refer to the diagram. We start at the left side of the diagram
cylinder Ø125. We follow the line until the intersection with the
velocity line of 0.5 m/s. From here we draw a horizontal line in the
diagram. This line shows us we need an equivalent throttling
bore of approximately 10 mm. Following this line horizontally we
crosses a few intersections. These intersections shows us the
minimum inner diameter (rightside diagram) in combination with
the maximum length of tube (bottomside diagram).
For example:
Intersection one: When a tube (14/11) will be used,
the maximum length of tube is 0.7 meter.
Intersection two: When a tube (—/13) will be used,
the maximum length of tube is 3.7 meter.
Intersection three: When a tube (—/14) will be used,
the maximum length of tube is 6 meter.
Example 4 : Determining tube size and cylinder
velocity with a particular cylinder and valve?
For an application using a 40 mm bore cylinder with a valve with
Qn=800 Nl/min. The distance between the cylinder and valve
has been set to 5 m.
Tube dimension: What tube bore should be selected to obtain
the maximum cylinder velocity? Start at pipe length 5 m, follow
the line up to the intersection with 800 Nl/min. Select the next
largest tube diameter, in this case Ø10/8 mm.
Cylinder velocity: What maximum cylinder velocity will be
obtained? Follow the line for 800 Nl/min to the left until it
intersects with the line for the Ø40 mm cylinder. In this example,
the speed is just above 1.1 m/s.

Introduction to the ATEX directive
Explosive atmospheres
Directive 94/9/EC defines an explosive atmosphere as a mixture of:
a) flammable substances – gases, vapours, mists or dusts
b) with air
c) under specific atmospheric conditions
d) in which, after ignition has occurred, combustion spreads to the
entire flammable mixture
(NB: with regard to dust, it may be that not all dust is combusted after
ignition has occurred)
An atmosphere with the potential to become an explosive atmosphere
during operating conditions and/or under the influence of the
surroundings is defined as a potentially explosive atmosphere.
Products covered by directive 94/9/EC are defined as intended for use
in potentially explosive atmospheres.
Harmonised European ATEX standard
The European Union has adopted two harmonised directives in the field
of health and safety. The directives are known as ATEX 100a and ATEX
137.
Directive ATEX 100a (94/9/EC) lays down minimum safety requirements
for products intended for use in potentially explosive atmospheres in
European Union member states. Directive ATEX 137 (99/92/EC) defines
minimum requirements for health and safety at the workplace, for
working conditions and for the handling of products and materials in
potentially explosive atmospheres. This directive also divides the
workplace into zones and defines criteria by which products are
categorised within these zones.
The table below describes the zones in an installation where there is a
potential for explosive atmospheres. The owner of the installation must
analyse and assess the area in which the explosive gas/dust mixture
may occur, and if necessary must divide it into zones. This process of
zoning then allows the correct plant and equipment to be selected for
use in the area.
The ATEX directive has been in force throughout the European Union
since 1 July 2003, replacing the existing divergent national and
European legislation relating to explosive atmospheres.
Please note that for the first time, the directive covers mechanical,
hydraulic and pneumatic equipment and not just electrical equipment as
before.
With regard to the Machinery directive 98/37/EC, note that a number of
external requirements in 94/9/EC refer to hazards arising from potentially
explosive atmospheres, where the Machinery directive only contains
general requirements relating to explosion safety (Annex I 1.5.7).
As a result, directive 94/9/EC (ATEX 100a) takes precedence over the
Machinery directive with regard to explosion protection in potentially
explosive atmospheres. The requirements in the Machinery directive are
applicable to all other risks relating to machinery.

Supplementary safety instructions for P1D-S cylinders
installed in Ex-areas
Serious, even fatal, damage or injury may be caused by the hot
moving parts of the P1D cylinders in the presence of explosive gas
mixtures and concentrations of dust.
All installation, connection, commissioning, servicing and repair work on
P1D cylinders must be carried out by qualified personnel taking account
of the following
• These instructions
• Markings on the cylinder
• All other planning documents, commissioning instructions and
connection diagrams associated with the application.
• Provisions and requirements specific to the application
• National/international regulations (explosion protection, safety and
accident prevention)
Real life applications
P1D cylinders are designed to provide linear movement in industrial
applications, and should only be used in accordance with the
instructions in the technical specifications in the catalogue, and within
the operating range indicated on the rating plate. The cylinders meet the
applicable standards and requirements of directive 94/9/EC (ATEX)
The cylinders must not be used underground in mines susceptible to
firedamp and/or flammable dusts. The cylinders are intended for use in
areas in which explosive atmospheres caused by gases, vapours or
mists of flammable liquids, or air/dust mixtures may be expected to
occur during normal use (infrequently)
Checklist
Before using the cylinders in an Ex-area, you should check the following:
Do the specifications of the P1D-S cylinder match the Ex-classification of
the area of use in accordance with directive 94/9/EC (previously ATEX
100a)
• Equipment group
• Ex-equipment category
• Ex-zone
• Temperature class
• Max. surface temperature
1. When installing the P1D-S cylinder, is it certain that there is no
potentially explosive atmosphere, oil, acids, gases, vapours or
radiation?
2. Is the ambient temperature as specified in the technical data in the
catalogue at all times?
3. Is it certain that the P1D-S cylinder is adequately ventilated and that
no forbidden additional heat is added?
4. Are all the driven mechanical components ATEX certified?
5. Check that the P1D-S cylinder is safely earthed.
6. Check that the P1D-S cylinder is supplied with compressed air.
Explosive gas mixtures must not be used for driving the cylinder.
7. Check that the P1D-S cylinder is not equipped with a metal scraper
ring (special version).
Installation requirements in Ex-areas
• The temperature of the supply air must not exceed the ambient
temperature.
• The P1D-S cylinder may be installed in any position.
• An air treatment unit must be attached to the inlet of the P1D-S
cylinder.
• The P1D-S cylinder must be connected to earth at all times, through
its support, a metallic tube or separate conductor.
• The outlet of the P1D-S cylinder must not open within an Ex-area, but
must be passed to the silencer or, preferably, removed and released
outside the Ex-area.
• The P1D-S cylinder may only drive units that are ATEX certified.
• Ensure that the P1D-S cylinder is not exposed to forces greater than
those permitted in accordance with the catalogue
• The P1D-S cylinder must be supplied with compressed air. Explosive
gas mixtures must not be used
• P1D-S cylinders with metal scraper rings must not be used in Ex-
areas
Inspecting cylinders during operation
The P1D cylinder must be kept clean on the outside, and a layer of dust/
dirt thicker than 1 mm must never be allowed to form.
Strong solvents should not be used for cleaning, because they can
cause the seal (material PUR) around the piston rod to swell, potentially
increasing the temperature. Inspect and verify that the cylinder, with
attachments, compressed air fittings, hoses, tubes, etc. meet the
standards of ”safe” installation.
