The Altecnic / Caleffi 253 Solar Safety Valve - 253046 is designed to regulate pressure within the primary circuits of solar heating systems. This valve is specifically chosen based on the required set pressure. As pressure increases within the system, the valve activates when the discharge pressure is reached, releasing excess pressure to the atmosphere. This vital function helps prevent potential damage to solar collectors and other system components caused by excessive pressure levels.
