Safety valve for solar systems with female-female connections |Caleffi 253

These safety relief valves are used to control pressure in the primary circuits of solar heating systems. When the calibrated pressure is reached, the valve opens to release the fluid into the atmosphere and prevents the pressure in the system from reaching levels that might damage the solar collectors and equipment installed. These particular series of products have been specially made and certified to work at high temperature with a glycol medium.
