Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation oper ations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or
damage, provide a relief valve for over-pressure protection as required by government or accepted industry codes and
good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against 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
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
materials with process media rests solely with the purchaser and end-user. Since some body/trim material combinations
are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first
contacting your Emerson Process Management sales office.
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
orientedsothatpipelineflowisinthesamedirectionasthearrowonthesideofthevalve.
3. The control valve assembly may be installed in any orientation unless limited by seismic criteria. However, the
normal method is with the actuator vertical above the valve. 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 Emerson Process Management sales office.
4. Use accepted piping and welding practices when installing the valve in the line. For flanged valves, use a suitable
gasket between the valve and pipeline flanges.
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. Shrink-fit pieces and threaded connections may also loosen. In
