The role of safety valves is to prevent the exceeding of the allowed operating pressure of closed heating circuits.
Safety valves are set to activate at a pressure of 2.5 or 3.0 bar. The spring inside the safety valve is lifted in case the installation pressure exceeds the specified value, causing the heating water to flow through the outlet pipe outward.
