CAUTION

Depending on valve body materials used, post-weld heat treating might be needed. Post-weld heat treatment can damage

internal elastomeric, plastic, and metal parts. Shrink-fit pieces and threaded connections might 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.
