Hydrolevel 550SV Low Water Cut-Off 30067439-890 specifically engineered to withstand theThe Hydrolevel 550SV Low Water Cut Off is a specialized safety control engineered for hot water boiler applications where a manual reset is required. This 120VAC unit (Part No. 45 551) utilizes a Safgard EL1214 SV sensing probe to monitor water levels via hydrostatic pressure and conductivity, providing 15,000 ohm sensitivity. Designed for direct mount installation via a 3 4" NPT connection, the 550SV prevents dry fire conditions by interrupting the
