UNPACKING
Each delivery includes a packing slip. When unpacking, check all delivered valves and accessories using this
packing slip.
Larger valves can be lifted using slings on the yoke or if present, using the lifting lugs or eyebolt connections
provided for this purpose. If slings are used, attach them so that the outer tubing or attaching parts are not
damaged.
WARNING: If slings are used, be aware that the centre of gravity of the valve may be above the lifting
point. In this case, secure or support the valve against rotating, to prevent damage or personnel

injury .
Report transport damage to the carrier immediately.
In case of discrepancies, contact your nearest FLOWSERVE sales office.
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.
COMMISIONING
Clean tubing prior to installing.
If possible, install the valve in an upright position (actuator on top), to ease maintenance. An upright installa-
tion position is important with low-temperature applications, in order to keep the distance between the packing
material and the medium as large as possible. The packing material then retains the ambient temperature as
much as possible.
NOTE: Do not insulate extension bonnets that are provided for hot or cold services
Make sure that sufficient overhead clearance above the actuator is maintained, to allow for disassembly of
plug from the valve body. See Installation, Operating and Maintenance manual (IOM) for detailed information.
After installing, check direction of flow again. The direction of flow is shown by the arrow on the valve.
If the valve is to be welded into the line, make sure that the valve is shielded from excessive heat. Welding must
be performed by qualified welders.
Connecting supply pressure and signal lines.
Control valves are supplied with a positioner. The end connections for supply pressure and signal are clearly
marked. Actuator and positioner are suitable for max. supply pressure as detailed on the product and within
the applicable IOM's. If the supply pressure exceeds the pressure specified, a pressure reducing station is
required. If instrument air is not available, install an oil separator/air filter in the air inlet line as defined by ISA
standard S7.3. All connections must be leak free.
