WARNINGS
Do not use these valves to control a power press
clutch or brake
These products are intended for use in industrial
pneumatic systems. They are designed and
tested for use in industrial pneumatic systems.
They are designed and tested for use with
filtered, lubricated compressed air at pressures
and temperatures within specified limits.
For use with fluids other than air, for non-
industrial applications or for life support systems,
consult Norgren. These products must not be
used in applications which do not fully comply
with all operating specifications.
Compressed air systems may contain lubricants
or contaminants which can attack materials
utilized in the manufacture of these products and
cause failure. The user in cautioned to be certain
that his compressed air system is fully compatible
with the materials utilized in these products.
High Energy Level – Compressed air systems
contain high levels of stored energy. Any attempt
to connect, disconnect or repair these products
when a system is under pressure can lead to
serious personal injury. Do not attempt to install,
operate or repair these products unless you are
trained in the proper techniques for working on
fluid power systems, or are under competent
supervision.
Code Compliance – the user of these products is
cautioned to conform to all applicable electrical,
mechanical, and other codes in the installation
and operation of these products.
Failure Modes – Through misuse, wear or
malfunction, these valves and related
accessories can fail in modes which can
simultaneously pressurize all ports to the highest
applied pressure level. They can also fail to shift
as expected upon the application or removal of
operator signals. These failure modes must be
considered in the use of these valves and related
accessories, and all appropriate safeguards to
prevent personal injury or property damage in the
event of such failure must be provided.
Repair and Conversion – Any time these valves
are disassembled for repair or conversion to a
different configuration, the reassembled valve or
accessory must be checked for leakage and
proper function prior to installation.
Electric Shock – To avoid electrical shock and the
possibility of serious or fatal injury, always
disconnect electrical power before servicing any
electrically operated valve.
INSTALLATION
Valve Exhaust
Adequately sized mufflers should be used in the
valve exhaust ports. Valves should not be
mounted with unprotected exhaust ports facing
upward. If exhaust is to be piped away, piping
should be installed horizontally or at a downward
angle from the valve to provide adequate
drainage and minimize the accumulation of
debris in the air line.
Pilot Supply
If the valve inlet pressure is less than the
specified minimum pilot pressure for the type of
solenoid operator used , then external pilot
supply must be provided.
