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 Ofce.

When ordering a replacement part, be sure to include

the complete eleven-character part number.
