YFL Pressure relief valves are also called safety valves which are used to make sure the pressure in the valve won't be higher than set pressure to ensure safety enviroment.
YFL Pressure relief valves working principle:
When the pressure in the system exceeds the pressure of pilot, the valve will be open immediately to release excess pressure to make sure the system pressure is lower than set pressure, so that the system is safe.
YFL Pressure relief valves can be also used as pressure substaining valve to prevent upstream pressure from dropping bleow the set pressure to ensure the stability of the system.
