Unpacking
1. While unpacking the valve, check the
packing list against materials received.
Lists describing valve and accessories are
in each shipping container.
2.
When lifting the valve from shipping
container, position the lifting straps through
the yoke legs to avoid damage to the tubing
and mounted accessories.
WARNING:
When lifting an
actuator with lifting straps
through the yoke legs, be aware
that the center of gravity may
be above the lifting point.
Therefore, support must be
given to prevent the actuator
from rotating.
3. Contact your shipper immediately if there is
shipping damage.
4.
Should any problem arise, call your
representative.
INSTALLATION
1. Before installing the valve, inspect it, and
other associated equipment, for any
damage and any foreign material.
2. Be sure that the body interior is clean, that
pipelines are free of foreign materials, and
that the valve is oriented in such a way that
pipeline flow is in the same direction as the
arrow on the side of the valve.
3. The assembly of the control valve may be
installed in any orientation unless otherwise
limited. However, whenever possible, the
valve should be installed with the actuator
vertical above the body. This is also
important for cryogenic applications to keep
the packing isolated from the flowing
medium, permitting the packing
temperature to remain close to ambient
temperature.
CAUTION:
Do not insulate
extension bonnets that are
provided for hot or cold
services.
4.
Be sure to allow sufficient overhead
clearance to provide for disassembly of the
plug from the valve body. Refer to
Table 2 below for overhead clearance
requirements.
Table 2: Overhead Clearance
Requirements
5. If welding the valve into the line, use
accepted piping and welding practices. In
the case that the valve has separable end
flanges, the half rings must be installed on
the body before bolting the valve into the
line in order to insure a tight connection.
WARNING
:
Failure to install half
rings on the valve body could
result in serious injury.
Note:
Depending on valve body materials
used, post weld heat-treating may be
required. This may cause damage to internal
elastometric and plastic parts. Shrunk-fit
pieces and threaded connections may also
loosen. In general, if post weld heat-treating
is to be performed, all trim parts should be
removed. Contact your Optimux sales office
for additional information.
