• Some hazards become active only after the product has been installed on
machinery/equipment. It is the responsibility of the end user to identify these hazards
and reduce the risks associated with them.
• For information regarding product reliability please contact Camozzi.
• Before using the product, first read the information contained within this document.
• The content of this use and maintenance instruction, must be observed in conjunction
with the instructions and additional information available from:
- Website http://www.camozzi.com
- Camozzi general catalogue
- Camozzi technical support
• Mounting and operation must only be carried out by qualified and authorized personnel,
in accordance with the following instructions.
• It is the machinery/equipment designer’s responsibility to choose the most appropriate
pneumatic component.
• For situations which are not covered in this manual and for situations where there
is the possibility of injury being caused to people or animals, please contact Camozzi
before using the product.
• Do not make any unauthorized changes to the product. If unauthorized changes are
made any subsequent damage to equipment, people or animals is the users responsibility.
• It is recommended that every safety rule associated with the product is strictly adhered to.
• Do not interfere with the machine or appliance without first checking that the working
conditions are safe.
• Before installing the product or beginning a maintenance procedure first ensure that any
lock-out controls are safely activated. The power supply should then be removed
(if necessary) along with the pressure supply system before exhausting all residual
compressed air in the system. Next drain any residual energy stored in springs,
capacitors, reservoirs or vessels. Be aware of any machinery movement due to gravity
when the air is removed from the system.
• After product installation or maintenance, reconnect the supply pressure and power
(if necessary) and check that the product is functioning correctly. If a leak is found
or the product is not functioning correctly then it should not be put into operation.
• To reduce the noise caused by air being discharged from the component, use silencers
or direct the fluid into an area where do not disturb.
1 General safety instructions
• When unpacking the product be careful not to damage it and pay attention at the
cleanliness of the environment.
• Size properly the passage of exhaust air, incorrect sizing can affect performances.
• Check the product for any damage which could have been caused during its transportation
or storage, like OR damaged or electrical pin bended.
• Separate any packaging materials so that they can be recovered and disposed
of in compliance with national regulations.
• Provide systems for locking the valve in place, using plates, pins, screw or any other
retention system that prevent the release of the valve when pressurized, taking care not
to damage the product.
• Before placing the component in housing, make sure that there are no burrs or other
debris that could potentially cause future breakdowns.
• In the presence of strong vibrations provide special devices/systems that can reduce
the effect on the component.
• User has to provide a safe electrical connection to the valve.
• The valve housing must be made according to the drawing below.

Use a correct housing
• The product must only be supplied with compressed air filtered to 5 µm and without
lubrication.
• The use of the product with liquids or not inert gases is not permitted.
• Connect pneumatically the valve in according with the scheme shown in figure below
3 Use
• Do not exceed the operating conditions illustrated in the Camozzi product catalogue.
• Unless special permission has been granted do not use the product in environments where
there may be direct contact with corrosive gases, chemicals, salt water, steam or water.
5 Use limitations
• Take all necessary precautions to prevent the sudden release of work pieces; then remove
the air supply and allow the release of any residual pressure before intervening.
• Exhaust the pressure from the whole circuit.
• Do not disassemble when pressure is applied.
• In order to guarantee the performances declared, switch the valves at least once every
30 days at nominal voltage
6 Maintenance
• Dispose of the product material according to the current environmental standards.
