Description
The Maxitrol R400B10-38 Pink Spring is a replacement calibration component used in compatible gas pressure regulator assemblies. It provides the spring force required for regulating diaphragm movement, control outlet pressure within the regulator. The 3/8-inch configuration is designed for use with applicable R400 series regulator setups where specific pressure adjustment features are required. Commonly found in fuel gas control equipment associated with HVAC systems, this spring supports stable regulator operation by maintaining the balance between inlet pressure and controlled outlet pressure during heating equipment operation.
