CAUTION

Depending on valve body materials used, post-weld heat treating might be needed. 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 needed, remove all trim parts. Contact your Emerson Process Management sales office

for additional information.

For screwed end connections, apply pipe compound to pipeline threads.

4. To allow continuous operation during inspection or maintenance, install a three-valve bypass around the control

valve assembly.

5. If you received the actuator and valve body shipped separately, refer to the appropriate actuator instruction manual

for the actuator mounting procedure.
