Description
NGRB Adjustment Springs for Norgas NGRB Gas Pressure Regulators
Selecting the correct NGRB adjustment spring determines the outlet pressure range of the Norgas NGRB gas pressure regulator. Each spring is color-coded and engineered to provide a specific adjustable outlet pressure band for commercial and industrial gas applications.
These OEM NGRB adjustment springs are used during regulator servicing, pressure range changes, and system reconfiguration for natural gas, propane (LP), and other non-corrosive fuel gas systems.
NGRB Spring Ranges, Colors & Part Numbers
Each spring is precision-calibrated to match the internal diaphragm and lever assembly of the NGRB regulator.
SBA — Gray Spring — 7–20″ W.C.
SBB — Yellow Spring — 20–40″ W.C.
SBC — Brown Spring — 1.3–2.9 PSI
SBD — Blue Spring — 2.2–4.3 PSI
SBE — White Spring — 3.6–8.6 PSI
SBF — Red Spring — 7.9–12.8 PSI
SBG — Silver Spring — 11.5–21.4 PSI
Proper spring selection ensures stable outlet pressure control and prevents over-adjustment outside the regulator’s intended operating range.
Designed Specifically for the NGRB Regulator
These springs are engineered exclusively for the Norgas NGRB gas pressure regulator.
Important:
NGRB springs are not interchangeable with NGR02, NGR04, NGR06, or NGR08 regulators. Each NGR series uses different internal components and pressure calibration ranges.
Using the correct adjustment spring ensures:
-
Accurate outlet pressure setting
-
Stable lock-up performance
-
Proper regulator response under varying load conditions
-
Long-term diaphragm and valve reliability
When Spring Replacement Is Required
Adjustment spring replacement is commonly performed when:
-
Changing outlet pressure range
-
Rebuilding or servicing the regulator
-
Correcting improper field adjustments
-
Matching regulator output to new downstream equipment
Unlike orifice sizing (which determines capacity), the adjustment spring determines the available outlet pressure range within the regulator body.
Factory-Order OEM Component
NGRB adjustment springs are genuine OEM components and are typically supplied as factory-order items depending on manufacturer availability.
Additionally, bulk quantities are availble for contractors, utilities, OEM equipment builders, and commercial gas installers.
