Parts Ordering
A serial number is assigned to each regulator, and it
is stamped on both the actuator and pilot nameplates.
If the pilot is replaced, the new pilot will have its own
serial number different from the main valve serial
number. Always indicate one or both serial numbers
when communicating with your local Sales Office.
When ordering a replacement part, be sure to include
the complete eleven-character part number.
