Installation

WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use
pressure‐relieving devices as required by accepted industry, local, state, or Federal codes, and good engineering practices.
Check with your process or safety engineer for any other hazards that may be present from exposure to process media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
CAUTION
The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop,
and controlled fluid conditions. Because some body/trim material combinations are limited in their pressure drop and
temperature range capabilities, do not exceed these conditions without first contacting your
Management sales office.
Inspect the valve and pipelines to ensure they are not damaged, are clean, and free of foreign material.
1. Before installing the valve, inspect the valve and associated equipment for any damage and any foreign material.
2. Make certain the valve body interior is clean, that pipelines are free of foreign material, and that the valve is
oriented so that pipeline flow is in the same direction as the arrow (see figure 2) on the side of the valve.
3. The control valve assembly can be installed in any orientation unless limited by seismic criteria. However, the
normal method is with the actuator vertical above the valve body (see figure 2). Other positions may result in
uneven valve plug and cage wear, and improper operation. With some valves, the actuator may also need to be
supported when it is not vertical. For more information, consult your
4. Use accepted piping and welding practices when installing the valve in the line. If a post‐weld heat treatment
process is to be applied to the valve end connections, and the valve has composition or elastomer trim parts,
remove the trim to avoid damage to the soft parts.
CAUTION
Depending on valve body materials used, post weld heat treating may be required. If so, damage to internal elastomeric
and plastic parts, as well as internal metal parts is possible. Shrunk‐fit pieces and threaded connections may loosen. In
general, if post weld heat treating is to be performed, all trim parts should be removed. Contact your Emerson Process
Management sales office for additional information.
5. If continuous operation is required during inspection or maintenance, install a three‐valve bypass around the
control valve assembly.
6. If the actuator and valve are shipped separately, refer to the actuator mounting procedure in the appropriate
actuator instruction manual and also see figure 2.
WARNING
Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however some
readjustment will be required to meet specific service conditions.
