Description
The Spence Engineering 05-05003-00 Spring is a calibrated adjusting spring used inside pilot-operated pressure control assemblies to set and maintain delivery pressure within the 5 to 50 PSI range. It is color-coded orange for identification and is fitted within the pilot mechanism to provide controlled tension for pressure regulation during operation. In HVAC systems, it is used in steam and fluid control regulator assemblies where stable pressure adjustment is required for consistent flow management in connected heating and process equipment.
