Inlet pressure is channeled through the internal equalization passage to the reseating relief control module. When inlet pressure exceeds the relief setting, the control module opens wide to allow pressure to enter the space on top of the piston. This causes the main valve seat to open and relieve the inlet pressure, provided the outlet pressure is at least 2 psi (0.14 bar g) lower. A 5 psid (.35 bar g) closing spring is standard on 3/4" through 1-1/4" valves.
