Safety valves are generally used in systems Sanitary and heating systems for pressure control where hot water collects or at heat generators.
The use of the safety valve prevents damage to the primary circuit of the solar system and its components by releasing pressure values that are higher than the calibration value of the valve itself into the atmosphere.
