responding to 2-10VDC speed signals for dynamic airflow management

The Kunkle Valve 6010HGM01AAM0015 is a high-capacity ASME Section IV safety relief valve engineered for low-pressure steam heating boilers and heavy-duty industrial processing

the 240009669 revision C is designed to be backward compatible with earlier revisions of the same control series used in ECR International boilers

Constructed with corrosion-resistant carbon steel

it may have weakened over time and should be replaced to ensure system reliability

Hydrolevel 550SVR Low Water Cut-Off THPU32HP7Y responding to 2-10VDC speed signalsThe Hydrolevel 550SVR Low Water Cut Off is a professional grade safety control designed to prevent dry firing in 120Vac gas or oil fired boilers. This Safgard 550SVR LWCO features a 30 second delay to filter out nuisance shutdowns from temporary water surges, ensuring the burner circuit only locks out during sustained low water events. As a secondary control for steam boilers or a primary limit for hot water systems, it meets ASME CSD 1 requirements
