2 Basic safety instructions
2.1 General notes
The product was constructed, manufactured, and tested according to the standards and
safety regulations listed in the current declaration of conformity.
The current declaration of conformity of HOERBIGER Automatisierungstechnik GmbH
and the EU-type examination certificates apply. The CE mark is on the piezo valves’ type
plate.
2.2 Intended use
The piezoelectrically-activated Pneumatic valve P8 serves to control compressed air
activated by the actuators in the standard pneumatic range.
The product is used especially in areas subject to explosion (Ex area according to
EN 1127-1) as well as in non-Ex areas.
Typical areas of application are process technology (turning and positioning drives) and
pneumatic process flow controllers.
1. To ensure perfect, risk-free function and a long life span of the device, follow the
notes in these operating instructions and adhere to the usage conditions and
permissible data according to the data sheet and type plate.
2. The usage planning and operation of the device must be done according to the
recognized rules of technology.
3. Prevent unintentional activations or impermissible interference by taking suitable
measures.
WARNING
Personal injury and property damage possible
■ Only have settings on the valve made by authorized specialized personnel trained by
the manufacturer with suitable tools.
■ Only operate valve in the pressure range specified on the data sheet.
■ Only use valve according to the protection type.
■ Heed the maximum switch-on duration according to the data sheet.

WARNING
Use is forbidden in case of:
■ Use of aggressive gases that can damage the valve.
■ Use of pneumatic variables that lie outside the area of application (see Technical
data, page 14).
■ Use of flammable gases that can also explode due to a lack of oxygen.
■ Use as safety valve.
■ Higher pressures than 1.1 bar if the medium is subject to explosion.
■ Use in acid rain or other corrosive atmospheres. Use only after consultation with the
manufacturer.
ð If the device should be operated below the freezing point, dried compressed air must
absolutely be used (pressure dew point 10 K below ambient temperature).

2.3 Personnel qualification
Unqualified personnel cannot detect risks and is therefore subject to greater dangers.
1. Only commission qualified personnel with the activities described in these
instructions.
2. Make sure that the personnel adheres to the locally valid regulations and rules for
safe and danger-conscious work.
The following target groups are addressed in these instructions:
Trained person: A trained person is somebody who has been trained extensively by the
operator in his tasks in connection with the safe operation of the valves.
Training is conducted by specialized personnel.
Electrically-qualified person: An electrically-qualified person is somebody who, based on
his specialized training, knowledge, and experience, as well as knowledge of the
applicable regulations, can judge and perform the work with which he is commissioned
and detect possible hazards independently.
Pneumatically-qualified person: A pneumatically-qualified person is somebody who, based
on his specialized training, knowledge, and experience with respect to pneumatic
components and systems as well as knowledge of the applicable regulations, can judge
and perform the work with which he is commissioned and detect possible hazards –
especially with respect to interactions between pneumatic, mechanical, electrical, and
control-technical components – independently.
Activity Authorization

2.4 Dangers
Here you will find information about various types of dangers and damage that can occur
in connection with operation of the product.
Electricity
1. Only have the device connected to the power supply and control lines by an
electrically-qualified person.
2. Only perform installation and maintenance work when the power is disconnected.
Pressure
1. Only have the device assembled by a pneumatically-qualified person.
2. Only install pneumatic components when the compressed air system is
depressurized.
3. During assembly and dismantling, adhere to the recognized rules of technology.
4. During work on pneumatic systems, heed the special safety regulations.
Explosion
1. Do not make any changes to devices that are operated in connection with areas
subject to explosion.
2. Avoid electrostatic charges (danger of explosion with use in Ex areas). These can
arise with friction processes, for example.
3. Use in Ex areas is only permitted with GSD according to DIN EN 175301-803-B.
Use of a GSD with LED in Ex areas is not permitted.
Operation
1. Settings on the valve only by authorized personnel trained by the manufacturer with
suitable tools.
2. Only use the device in industrial applications for compressed air and permissible
gases. Adhere to the working pressure according to the data sheet.
3. The device is only approved for proper or intended use.
4. Do not open the device.
5. Do not remove type designations or seals that do not serve transport protection.
6. Heed the prescribed air purity.
Repair and maintenance
1. Only have repair work on the valve performed by the manufacturer since only the
manufacturer has the equipment for optimal adjustment after repair and can
therefore guarantee perfect function.
2. Do NOT maintain the inner parts of the device.
3. Send the complete valve to the manufacturer for maintenance and service.
