Description
The Maxitrol R9110-38 Pink Spring is a pressure control spring used in gas regulator assemblies to maintain outlet pressure within a defined range. It is calibrated for a 3 to 8 inches water column (W.C.) operating range, allowing stable regulation of gas flow in compatible systems. This spring is commonly used in RV91 and 210E series regulators, where consistent pressure control is required for burner operation. Within HVAC systems, it is fitted inside gas control assemblies to maintain steady fuel delivery to heating equipment. Its color-coded construction identifies the specific pressure range for correct selection and installation.
