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.
