The Altecnic / Caleffi 253 Solar Safety Valve - 253043 is designed to effectively manage pressure within the primary circuits of solar heating systems. This valve is selected based on the required set pressure. As system pressure increases, the valve will open upon reaching the designated discharge pressure, releasing excess pressure to the atmosphere. This mechanism prevents harmful pressure levels that could damage solar collectors and other components within the system.
