Spence 05-01673-00 Diaphragm Refrigerant responsible for converting modulated airThe Spence 05 01673 00 Diaphragm is a critical pressure containing component specifically engineered for the 3 inch E2 pilot operated regulator. As a veteran technician knows, maintaining the integrity of the main valve diaphragm is essential for preventing seat leakage and ensuring precise steam pressure regulation. This 12 inch replacement diaphragm is constructed from high temp synthetic rubber, often Hycar or reinforced Neoprene, allowing it to
