1 General Information
The following instructions are designed to assist in unpacking, installing and
performing maintenance as required on Flowserve Mark 200 control valves.
Product users and maintenance personnel should thoroughly review this
bulletin prior to installing, operating or performing any maintenance on the
valve. Separate Installation, Operation, and Maintenance instructions cover
additional 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.
WARNING: Standard industry safety practices must be adhered
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
information about fastener materials, contact your Flowserve representative.
