Spence Engineering 05-05003-00 Orange Spring

The Spence Engineering 05-05003-00 Orange Spring is a critical component for technicians maintaining Spence D-Pilot and D5 pressure reducing pilots. Designed for high-performance steam and fluid systems, this orange adjusting spring provides a precise delivery pressure range of 5-50 PSI. Built with a 1/4-inch wire diameter, it ensures consistent tension and reliable set-point stability when integrated into a Spence Type E or Type C main valve assembly. This spring is essential for contractors performing routine maintenance or recalibrating pressure regulators to meet specific downstream requirements in industrial HVACR environments. Its heavy-duty construction is engineered to withstand the thermal and mechanical stresses of steam pressure regulation, making it the standard choice for professional HVAC pilot repair operations.
