Itron Adjustment Spring WC for Gas Regulators

Itron adjustment springs are replacement springs for Itron gas pressure regulators. They set the outlet pressure of the regulator, which is measured in inches of water column (WC). Each spring works with the regulator's adjusting screw. It applies controlled force to the diaphragm and valve assembly, which holds downstream gas pressure steady. These springs are also called regulator main springs or pressure adjustment springs.

Key Features:

• Made as a replacement part for Itron gas regulators, including the B31R, B34SR and B42 series
• Field-interchangeable design lets you change the outlet pressure range by swapping the spring, without replacing the whole regulator
• Color-coded springs identify each pressure range, which makes selection and inspection easier
• Helps keep burner and appliance pressure stable during gas flow
• Works with the regulator's adjusting screw to set the final outlet pressure

Match the spring's color and pressure range to your regulator model and the outlet pressure you need. Itron notes that adjustment springs are not interchangeable between every regulator series. For example, B42 and B42HP springs differ. Check the specifications for the individual part number before you install one.
