SS-83 Valve
March 2013
Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations 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 specified when the valve was purchased 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. Because 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.
If hoisting the valve, use a nylon sling to protect the surfaces. Carefully position the sling to prevent damage to the actuator
tubing and any accessories. Also, take care to prevent people from being injured in case the hoist or rigging slips
unexpectedly. Be sure to use adequately sized hoists and chains or slings to handle the valve.
1. Before installing the valve, inspect the valve body cavity and associated equipment for any damage and any foreign
material.
2. Make certain the 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 on the side of the valve.
3. If possible, install the valve with the valve stem vertical. All valves with size 80 or larger actuators mounted between
45_ above and 45_ below horizontal should be supported. Small actuators might also need support if vibrational or
other non-gravitational forces are present. For more information on seismic considerations, consult your Emerson
Process Management sales office.
4. Use accepted piping, flange, or welding practices when installing the valve in the line. For flanged valve bodies, use
a suitable gasket between the body and pipeline flanges.
Note
For valves with a welding-end, 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 general, if post weld heat treating is to be performed, remove all trim parts. Contact your Emerson Process
Management sales office for additional information.
