Description
The Maxitrol R400B10-512 Spring is used a calibrated internal component within gas pressure regulators to maintain controlled outlet pressure levels. The 512″ WC specification represents the adjustable pressure range in inches of water column, while the blue color identifies the spring grade matched for R400 series regulators. Commonly applied in HVAC systems, this spring is fitted inside regulator assemblies that supply gas to burners and combustion equipment. It supports consistent pressure regulation across conditions, maintains steady fuel delivery, and proper operating balance within compatible gas-fired heating applications.
