These products are intended for use in industrial compressed air or hydraulic systems only. Do
not use these products where pressures and temperatures can exceed those listed under
‘
Before using these products with fluids other than those specified, for non-industrial
applications, life-support systems, or other applications not within published specifications,
consult NORGREN. Through misuse, age, or malfunction, components used in fluid power
systems can fail in various modes. The system designer is warned to consider the failure modes
of all component parts used in fluid power systems and to provide adequate safeguards to
prevent personal injury or damage to equipment in the event of such failure.
System designers must provide a warning to end users in the system instructional
manual if protection against a failure mode cannot be adequately provided.
System
designers and end users are cautioned to review specific warnings found in instruction sheets
packed and shipped with these products.
Specific warnings:
• Check if classification of the valve island and marking on the item of equipment are able for
case of operation.
• Check technical data, such as operating pressure, voltage level, current type and
temperature, on the product label or in the data sheets for compliance with the existing
operating conditions.
• After removing the packaging, make sure that no contamination enter into the system.
• Check before the installation of the system that no contamination exists in the piping and
valve island.
• Check during installation of the system that gaskets will not become damaged.
• Please consider the information of this operating manual as well as the use conditions and
permissible data, which are on the product labels.
• Adapt to the general rules of technology when selecting and using an item of equipment.
• Take measures to avoid unintentional or improper activation.
• Prior to the first electrical operation, ensure no danger would result from the medium
exhausting from any open ports.
• Consider in case of pressurised systems that lines, valves and other components should not
be removed.
• ATTENTION: There is some risk of injury! The surface of pilot valves could become very
warm in continuous operation.
• ATTENTION: Valves with NO function (normally open) are open without pilot pressure.
During commissioning, protection against exhausted medium has to be provided.
• Leak and strength tests on open and closed valves are admissible until max. 1.5 times the
max. operating pressure. It is not allowed to operate the valve during these tests.
• Never use the valve island as lever arm or a step for climbing.
• Protect the valve island from falling objects.
