Function 5
IS12-PD series valves are electrically operated pneumatic 5/2 directional
valves with an integrated spool position detection. Spool position detection
is realized by means of the following system: A magnet is integrated in the
piston (spool) of the valve and an ST4 series proximity sensor with an M8x1
connection is installed in a sensor housing on valve side 14.
The sensor LED indicates the position of the spool. This allows the user to
detect whether the valve is in the home position (sensor LED is lit) or in the
switching state (sensor LED is not lit). In addition, the position of the
sensor is transferred to the controller via the M8 connection, PIN 4 (OUT).
The sensor is switched on when the spool is located on valve side 14, meaning
in home position. In this case, the sensor LED is lit.
The sensor is switched off when the spool is located on valve side 12, meaning
in the switching position. In this case, the sensor LED is not lit.
Depending on the order, IS12-PD series vales have different features:
- With or without manual override (MO)
- With internal or external pilot
Home position, sensor LED lit
When the valve is not actuated electrically, it is in home position. The spool
is positioned so that connections 1 and 2 and connections 4 and 5 are
connected respectively. With typical use, connection 2 is under pressure while
connection 4 is pressure-free. The sensor LED is switched on and indicates
that the valve is in the home position. The output voltage is applied to pin 4
(OUT). To ensure the system is not under pressure in home position, the
working connection to the system must be connected at connection 4.
Switching position, sensor LED not lit
When the valve is actuated electrically, it is in switching position. The
spool is positioned so that connections 2 and 3 and connections 1 and 4 are
connected respectively. With typical use, connection 2 is pressure-free while
connection 4 is under pressure. The sensor LED is switched off and indicates
that the valve is in the switching position. 0 volts are applied to pin 4
(OUT). To ensure the system is under pressure in the switching position, the
working connection to the system must be connected at connection 4.
Sensor signal change when pressurizing port 4
When the valve is switched on, the spool moves from valve side 14 to valve
side 12.
During spool movement, the signal of the sensor switches from “ON” to “OFF”.
Sensor signal change when exhausting port 4
When the valve is switched off, the spool moves from valve side 12 to valve
side 14.
During spool movement, the signal of the sensor switches from “OFF” to “ON” if
port 4 is connected to port 5.
Transportation and Storage
The valve is packaged to protect it from contamination. Do not remove the packaging until just before assembling the valve.
Transportation
CAUTION
Danger of injury from falling!
An IS12-PD module with spool position detection can weigh up to 410 g and
injure persons in falling.

▶ Never use IS12-PD valves that were stored for longer than two years.
Assembly
WARNING
Danger of injury due to assembly of the product while the system is running!
Assembly of the product while the system is running can cause major injuries
from moving machinery.
▶ Bring the system mode into a state in which working movements are no longer
possible. Wait until all moving machine parts come to a standstill, and
protect the system against being switched on.
Danger of injury due to suspended useful loads!
Useful loads that are kept suspended by compressed air pose a danger if they
are not secured before the pressure is switched off in the system.
▶ Guide the useful loads into a safe position or remove them from the system.
▶ You may only then switch off the pressure in the relevant section of the
system.
Danger of injury due to stored energy (compressed air)!
When the system is at a standstill, there is still a danger due to stored
energy (compressed air).
▶ Generally avoid storing compressed air.
▶ Exhaust the system in which the valve is to be installed.
▶ Remove all other sources of danger in the immediate work area that may
result from stored energy in the system.
NOTICE
Damage to the IS12-PD valve when using the incorrect tightening torque!
Insufficient or excessive tightening torques can result in operating problems
or damage the product.
▶ Always observe the tightening torques specified in these operating
instructions.
The following must be observed during assembly:
■ The valve is packaged to protect it from contamination. Do not remove the
packaging until just before assembling the valve.
■ All compressed air connections and control elements must remain freely
accessible after installation.
■ The valve must be attached in such a way that it cannot be loosened by
jolts, vibrations, or the like.
■ The position of the sensor was fixed at the factory and secured with a
clamping screw with resin. The sensor must not be replaced or disassembled, or
its position changed. The sensor housing ( 4 ) is bolted to the valve
cover ( 3 ) and secured with resin. The sensor housing must not be
replaced or disassembled, or its position changed.
▶ Make sure that the valve is only used as described in “Bestimmungsgemäße
Verwendung”. An example for use in safety-relevant controls for exhausting
systems and machines is described in “17 Exemplarische Steuerung”.
Preparing for assembly
Prepare for assembly as follows:
- Stop system operation and protect it against being switched on.
- Return all suspended loads to a statically secure position or remove them from the system.
- If required, exhaust stored compressed air from system parts in the immediate work area.
- Make sure the relevant section of the system is not under pressure or voltage and protect it from being switched on.
- Secure self-turning or other movable system parts before starting assembly.
- Before assembly, check the sensor cable for damage. If the sensor cable is damaged, you must replace the entire valve.
Installing the valve
Any mounting orientation may be used with the IS12-PD valve.
Assembly consists of five steps:
- mechanical fastening to the system,
- connection to the compressed air supply of the pneumatic system,
- connecting the sensor,
- coil assembly, and
- coil connection.
Mechanically fastening the valve to the system
To operate the valve, it must be mounted to a base plate. The base plate is
not part of the scope of delivery.
The base plates are fastened to the assembly surface or in a valve system in
various manners, depending on the type.
Suitable own mounting material must be used in order to fasten the base plates or the valve system to the assembly surface. The general rules of technology apply here.
- Mount the base plate or the valve system on the assembly surface in a way that prevents mechanical strain. While doing so, observe the maximum permissible tightening torque values for the mounting screws.
- Always mount the base plate or the valve system on an assembly surface in a way that prevents the valve, the base plate, and the valve system from loosening in the event of jolts, vibrations, etc.
- Install the base plate in your system in a manner where the pneumatic connections are always accessible.
- Please see the catalog pages in the AVENTICS online catalog for the exact dimensions for fixing your base plate or valve system.
To mount the valve on the base plate:
- Place the base plate seal ( 1 –15 ) on the underside of the valve so that the pneumatic ports are not covered.
- Fix the IS12-PD valve to a size 1 base plate in accordance with ISO 5599-1 using the four captive screws ( 1 –14 ).
Tightening torque: 2.2 ±0.3 Nm
Connecting the compressed air supply
The valve is supplied with compressed air via a base plate or a valve system.
▶ Make the pneumatic connections as follows:
- Connection 1 to the supply pressure
- Connections 3 and 5 to the exhaust
- Connections 2 and 4 to the working connections
Connecting the sensor
The contacts on the M8x1 connection have the following pin assignment (see

NOTICE
Malfunction due to damaged sensor cable!
If the seal in the sensor plug is missing or defective, protection class IP65
is not achieved.
▶ Make sure that the seals are integrated in the plug and not damaged.
Damage to the sensor due to excessive voltage!
The ST4 sensor may only be operated with 10–30 V DC even if you use 110 V AC
or 230 V AC coils.
▶ Make sure that the ST4 sensor is always operated within the voltage limits.
▶ Connect the sensor plug and the knurled nuts to the controller. See the
table for the pin assignment (above).
We recommend using short circuit protection.
Assembling the coil
NOTICE
Use of improper coils!
Using improper coils can result in malfunctions.
▶ Only used the coils named under “Intended use”.
You can assemble the coil in 5 different positions so that the contacts face upward, 45°, or 90° to the side.
-
Assemble the coil on the pole tube.
The small centerings must be fixed in the steel plate so that the coil is prevented from turning. -
Tighten the lock nuts ( 1 –9) on the thread at the end of the pole tube.
Tightening torque: 0.6 +0.2 Nm.
Connecting the coil
To connect the coil, you need cables with the following connections:
■ one electrical connector according to ISO 4400, form A, CN1 series,
■ or one M12x1 socket, 3-pin, A-coded.
The cable and connectors are not part of the scope of delivery. The pin
assignments
for the connection cables are displayed in Fig. 3
▶ Connect the electrical connector or the M12 socket to the coil. Make sure
that the seals have been inserted correctly. Tighten the screw on the coil
(form A) or the knurled nuts to the M12 plug.

Commissioning
WARNING
Danger of injury while working on the system!
Working while the system is running can cause major injuries from moving
machinery.
▶ Maintain a sufficient safety distance to moving machine components.
▶ Do not work on the system while it is running.
Risk of injury when actuating the manual override!
Uncontrolled movement of the system components!
- Before actuating the manual override, make sure that it will not trigger uncontrolled system movements.
Checking the connections
▶ Before commissioning, make sure that all plugs are correctly connected to
ensure protection class IP65.
Initial check of the spool position detection
For valves with manual override (MO), you can simplify commissioning by
actuating the MO. The MO on the IS12-PD valves is “without detent”. This means
that the valve switches to home position when you discontinue actuating the
MO.
▶ Before initial operation, check whether the “spool position detection”
function is working properly.
– If the valve is not actuated (electrically or mechanically on the MO), the
sensor LED should be lit. The output voltage is applied to pin 4 (OUT).
– If the valve is actuated (electrically or mechanically on the MO), the
sensor LED must not be lit. 0 volts are applied to pin 4 (OUT).
Operation
WARNING
Loss of function if the minimum control pressure is not met!
If the control pressure falls below 3 bar, the valve can no longer switch
reliably.
The safety function is then affected.
▶ Make sure that the minimum control pressure is always above 3 bar.
▶ For valves with internal pilot, ensure the operating pressure with an
appropriate pressure sensor, or the control pressure for valves with external
pilot respectively.
Spool position detection malfunction due to magnetic sources!
Spool position detection may malfunction due to magnetic sources. The safety
function is then affected.
▶ Make sure that no magnetic sources are located near the valve.
▶ Make sure that the operating conditions correspond to the catalog
specifications for size 1 IS12-PD valves, for CO1 coils, and for ST4 sensors,
particularly with regard to temperature, pressure, voltage supply, and
mechanical and climatic loads (see also chapter “15 Technische Daten”).
▶ Use compressed air with the following properties:
- Maximum particle size 5 μm
- Oil content of compressed air 0 mg/m³ – 5 mg/m ³
- The pressure dew point must be at least 15°C below the ambient temperature and must not exceed 3°C.
- The oil content of the compressed air must remain constant over the whole service life.
Care and Maintenance
Cleaning
NOTICE
Damage to the product due to the use of aggressive cleaning agents!
The product can be damaged if washed with a cleaning agent. The chemical
resistance of the valve material to such products is not guaranteed.
▶ Make sure that no cleaning agents come into contact with the valve.
Damage to the product due to washing at high pressures and temperatures!
The product will be damaged if you clean it with high pressure and/or at a
high temperature.
▶ Make sure that the product is not cleaned with high pressure and/or at a
high temperature.
Maintenance
WARNING
Risk of injury while working on a running system!
Working while the system is running can cause major injuries from moving
machinery.
▶ Bring the system mode into a state in which working movements are no longer
possible. Wait until all moving machine parts come to a standstill, and
protect the system against being switched on.
Danger of personal injury due to uncontrolled movements!
For valves with manual override (MO), you can simplify system maintenance by
mechanically actuating the MO. The MO on the IS12-PD valves is “without
detent”.
This means that the valve switches to home position when you discontinue
actuating the MO.
▶ Make sure that no uncontrolled movements occur in the process.
IS12-PD valves are maintenance-free. However, the seals of the valves may age faster under aggressive ambient conditions. Defective seals will lead to pneumatics leaks and non-compliance with the IP65 protection class.
- Check regularly whether all plug connectors are firmly fitted.
- Establish the maintenance intervals according to your ambient conditions and enter them in the system-dependent maintenance plan.
- Observe the system-specific maintenance intervals.
The operator is responsible for determining the maintenance intervals.
Removing the Valve from the System
WARNING
Danger of injury if valve disassembled under pressure or voltage!
Uncontrolled movement of the system components!
▶ Make sure that the system is not under pressure or voltage when you
disassemble the valve, coil, electrical connector, or the M8x1 socket.
NOTICE
Contamination during disassembly!
During disassembly, greases or lubricant may escape from the valve.
▶ Make sure that the environment is not contaminated with greases or
lubricant during disassembly.
- Stop system operation and protect it against being switched on.
- Ensure that the useful load has reached a stable position.
- Make sure that the relevant section of the system is not under pressure and protect it against being switched on.
- Remove the electrical connector from the coil.
- Remove the sensor plug from the controller.
- Loosen the four mounting screws on the valve and remove the valve from the base plate.
This concludes the disassembly.

Example Control
Figure 4 shows an example of a safety-relevant control for exhausting a
cylinder.
The block function is realized through two IS12-PD valves and one non-return
valve.
The following circumstances were taken into account in the circuit diagram in
Fig. 4 :
- To enable the correct behavior of the valve, the valve must not be actuated until a minimum operating pressure of 3 bar has been built up in the system. The valve pilot supply is then sufficient to correctly switch the valve.
- A pressure regulator is provided in an appropriate location in the supply line to build up a stable pressure.
