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
additional information.
