Maxitrol R9110-515 Green Replacement Spring
The Maxitrol R9110-515 is a genuine OEM green replacement spring designed specifically for use with Maxitrol RV91 and 210E Series gas pressure regulators. Color-coded green for easy identification, this spring sets the outlet pressure range to 5–15″ water column (w.c.), making it the correct choice for applications requiring precise regulation within that pressure band. Swapping springs is a straightforward way to re-range an existing regulator without replacing the entire unit, reducing downtime and parts cost.
