1 GENERAL INFORMATION
1.1
Using This Document
Product users and maintenance personnel should thoroughly
review this bulletin prior to installing, operating, or performing
any maintenance on the valve.
The following instructions are designed to assist in
unpacking, installing and performing maintenance as
required on Logix® 500MD+ positioners. Series 500 is the
term used for all the positioners herein; however, specific
numbers indicate features specific to model (i.e., Logix 520
indicates that the positioner has HART® protocol). See Logix
500MD+ Model Number table in this manual for a breakdown
of specific model numbers.
Separate Flow Control Products User Instructions cover the
valve (such as IOM 1 or IOM 27) and actuator (such as IOM
2 or IOM 31) portions of the system and other accessories.
Refer to the appropriate instructions when this information is
needed. In most cases FLOWSERVE valves, actuators and
accessories are designed for specific applications with regard
to medium, pressure and temperature. For this reason they
should not be used in other applications without first
contacting the manufacturer.
To avoid possible injury to personnel or damage to valve
parts, DANGER, WARNING and CAUTION notes must be
strictly followed. Modifying this product, substituting non-
factory parts or using maintenance procedures other than
outlined could drastically affect performance and be
hazardous to personnel and equipment, and may void
existing warranties.
1.2
Terms Concerning Safety
The safety terms DANGER, WARNING, CAUTION and
NOTE are used in these instructions to highlight particular
dangers and/or to provide additional information on aspects
that may not be readily apparent.
NOTE: Indicates and provides additional technical
information, which may not be very obvious even to qualified
personnel.
CAUTION: Indicates that minor personal injury and/or
property damage can occur if proper precautions are not
taken.
WARNING: Indicates that death, severe personal injury
and/or substantial property damage can occur if proper
precautions are not taken.
DANGER: Indicates that death, severe personal injury
and/or substantial property damage will occur if proper
precautions are not taken.
Compliance with other, not particularly emphasized notes,
with regard to transport, assembly, operation and
maintenance and with regard to technical documentation
(e.g., in the operating instruction, product documentation or
on the product itself) is essential, in order to avoid faults,
which in themselves might directly or indirectly cause severe
personal injury or property damage.
1.3
Protective Clothing
WARNING: Standard industry safety practices must be
adhered to when working on this or any process control
product. Specifically, personal protective and lifting devices
must be used as warranted.
FLOWSERVE products are often used in problematic
applications (e.g. extremely high pressures, dangerous, toxic
or corrosive mediums). In particular, valves with bellows
seals point to such applications. When performing service,
inspection or repair operations always ensure, that the valve
and actuator are depressurized and that the valve has been
cleaned and is free from harmful substances. In such cases
pay particular attention to personal protection (protective
clothing, gloves, glasses etc.).
1.4
Qualified Personnel
Qualified personnel are people who, on account of their
training, experience, instruction and their knowledge of
relevant standards, specifications, accident prevention
regulations and operating conditions, have been authorized
by those responsible for the safety of the plant to perform the
necessary work and who can recognize and avoid possible
dangers.
In unpacking, installing and performing maintenance as
required on FLOWSERVE products, product users and
maintenance personnel should thoroughly review this bulletin
prior to installing, operating or performing any maintenance.
1.5
Valve and Actuator Variations
These instructions cannot claim to cover all details of all
possible product variations, nor can they provide information
for every possible example of installation, operation or
maintenance. This means that the instructions normally
include only the directions to be followed by qualified
personal where the product is being used for its defined
purpose. If there are any uncertainties in this respect
particularly in the event of missing product-related
information, clarification must be obtained via the appropriate
Flowserve sales office.
1.6
Valve and Actuator Installation
DANGER: Before installation, check the order-no.,
serial-no. and/or the tag-no. to ensure that the valve/ actuator
is correct for the intended application.
Do not insulate extensions that are provided for hot or cold
services. Pipelines must be correctly aligned to ensure that
the valve is not fitted under tension. Fire protection must be
provided by the user. See specific valve and actuator
documentation.
1.7
Spare Parts
Use only FLOWSERVE original spare parts. FLOWSERVE
cannot accept responsibility for any damages that occur from
using spare parts or fastening materials from other
manufactures. If FLOWSERVE products (especially sealing
materials) have been in storage for longer periods check
these for corrosion or deterioration before using these
products. See section 4 STORAGE AND UNPACKING for
more information.
1.8
Service / Repair
To avoid possible injury to personnel or damage to products,
safety terms must be strictly adhered to. Modifying this
product, substituting non-factory parts, or using maintenance
procedures other than outlined in this instruction could
drastically affect performance and be hazardous to personnel
and equipment, and may void existing warranties.
Between actuator and valve there are moving parts. To avoid
injury FLOWSERVE provides pinch-point-protection in the
