Safety Valve 10mm Preset 11bar is an emergency discharge valve that is used in order to prevent danger in case of an unexpected pressure increase inside your compressor.
If the pressure of the compressor rises more than expected due to any reason, the safety valve, will operate and discharge the excessive pressure.
The safety valve is composed of a mechanical system. It suppresses the air outlet until a certain pressure thanks to a spring inside which has a certain level of tension. However, in case of more pressure, the power of the pressure defeats the tension power of the spring and provides the discharge of air.
