Pilot-operated principle:

It may also be a pilot-operated safety valve, which consists of a main valve and a pilot valve. When the system pressure is normal, the pilot valve is closed, the pressure in the upper chamber of the main valve piston is balanced with the pressure in the lower chamber, and the main valve is closed. When the system pressure exceeds the set pressure of the pilot valve, the pilot valve opens, the pressure in the upper chamber of the main valve is released through the pilot valve, and the pressure in the lower chamber of the main valve pushes the main valve disc to open to achieve pressure relief.
