Hydrolevel EL1220-SV Sensing Probe 328140-751 this valve provides the robustThe Hydrolevel EL1220 SV is a specialized low water cut off (LWCO) sensing probe designed for high performance liquid level monitoring in hydronic heating and steam boiler systems. Featuring a rugged short ceramic insulator, this 45 221 part number is engineered for tight clearance installations where standard probes may interfere with internal castings or piping. The 1 2" NPT threaded connection ensures a secure, leak proof seal, while the 2 1 16"
