The specifications of safety valves are determined based on the discharge rate. If there are two safety valves, it seems that either the flow rate in your system is extremely high, and no safety valve with a high enough capacity exists; therefore, two valves have to be used for exhaust.
First, determine where the safety valve will be installed and what the safe pressure level should be. Generally, to achieve rapid pressure release
