The Altecnic / Caleffi 527 Safety Valve - 527560EST is essential for effective pressure control in heating systems, particularly in heat generators, hot water storage units, and hydraulic systems. This safety valve is designed to open when the preset pressure is reached, discharging excess pressure into the atmosphere to ensure that the pressure in the system remains safely below dangerous levels for both the generator and the installed components. The 527 EST series valves are also fail-safe devices, ensuring reliability of operation even in the event of diaphragm wear or breakage.
