1. This material is not listed in EN 12516‐1 or ASME B16.34. Also see the Installation section.
2. The designations PN or 150 and 300 are used only to indicate relative pressure‐retaining capabilities and are not EN or ASME pressure‐temperature rating class designations.
3. This material is not listed in EN 12516-1. Also see the Installation section.
Installation
Key numbers in this procedure are shown in figure 11 unless otherwise indicated.
WARNING
Always wear protective gloves, clothing and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be certain the service
conditions do not exceed either the valve body rating or the flange joint rating, or other limits given in table 1 or on the
nameplate. Use pressure‐relieving or pressure‐limiting devices to prevent the service conditions from exceeding these
limits.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section on page 8
in this manual.
CAUTION
The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop,
and controlled fluid conditions specified in the customer's order. Because some valve body/trim material combinations are
limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without
first contacting your Emerson Process Management sales office.
The maximum allowable inlet pressures for steel and stainless steel valve bodies are consistent with the
pressure‐temperature ratings shown in table 1, except where further limited by the trim and packing material
temperature capabilities given in table 3. Valves are also available in CW2M and M35‐2 valve body materials. The
CW2M valve body material is not listed in EN 12516-1 or in ASME B16.34. The M35-2 valve body material is listed in
ASME B16.34, but is not listed in EN 12516-1. Valve bodies constructed of these materials mate with EN and ASME
flanges, but must not be installed in systems requiring conformance to EN or ASME standards if not included in EN or
ASME pressure/temperature ratings. Maximum allowable inlet pressures for 8580 valve bodies made of CW2M or
M35‐2 construction materials are shown in table 4.
