FCD FCAIM0100-02 Mark 100 Installation, Operation and Maintenance Instructions 3
1 General Information
The following instructions are designed to assist in unpacking,
installing and performing maintenance as required on Flowserve
Mark 100 control valves. Product users and maintenance per-
sonnel should thoroughly review this bulletin prior to installing,
operating or performing any maintenance on the valve. Separate
Installation, Operation, and Maintenance instructions cover ad-
ditional features (such as special trim, actuators, handwheels,
packing and positioners.)
To avoid possible injury to personnel or damage to valve parts,
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.
c WARNING: Standard industry safety practices must be ad-
hered to when working on this or any other process control
product. Specifically, personal protective and lifting devices
must be used as warranted.
NOTE ON FASTENERS: Selecting the proper fastener material is
the responsibility of the customer. Typically, the supplier does not
know what the valve service conditions or environment may be.
Flowserve’s standard body bolting material is B7/2H. B8 (stainless
steel) is optional for applications more than 800°F / 425°C and with
stainless steel or alloy-body valves. The customer therefore must
consider the material’s resistance to stress corrosion cracking in
addition to general corrosion. As with any mechanical equipment,
periodic inspection and maintenance is required. For more informa-
tion about fastener materials, contact your Flowserve representative.
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.
b DANGER: indicates that death, severe personal injury and/or
substantial property damage will occur if proper precautions
are not taken.
c WARNING: indicates that death, severe personal injury and/
or substantial property damage can occur if proper precau-
tions are not taken.
a CAUTION: indicates that minor personal injury and/or prop-
erty damage can occur if proper precautions are not taken.
NOTE: indicates and provides additional technical information, which
may not be very obvious even to qualified personnel.
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 instruc-
tions, 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.
3 Unpacking
1. While unpacking the valve, check the packing list against materi-
als received. Lists describing valve and accessories are in each
shipping container.
2. When lifting the valve from shipping container, use the lifting
lugs attached to the bonnet bolting. Take care to position lifting
straps to avoid damage to the tubing and mounted accessories.
c WARNING: When lifting a valve using the lifting lugs, be
aware that the center of gravity may be above the lifting
point. Therefore, support must be given to prevent the
actuator from rotating. Failure to do so can cause seri-
ous injury to personnel, damage to the valve or nearby
equipment.
3. Contact your shipper immediately if there is shipping damage.
4. Should any problem arise, call your Flowserve representative.
