Standard Setting: Note: A 6.9 Bar (100 PSI) pressure differential must be maintained
103.5 Bar (1500 PSI) @ 11.3 LPM (3 GPM) between the two relief valve settings. If both reliefs are adjustable and
have the same pressure range; it is not necessary to repeat the BC

Standard Setting: i.e. XRDH101S50-8T means that both A & B reliefs are screw adjustable
172.4 Bar (2500 PSI) @ 11.3 LPM (3 GPM) and have a range of 138 - 345 Bar (2000 - 5000 PSI). Bodies & Cavities
