30 34.5 - 207 Bar (500 - 3000 PSI) Bodies & Cavities
Standard Setting: Note: A 6.9 Bar (100 PSI) pressure differential must be maintained
103.5 Bar (1500 PSI) @ .95 LPM (.25 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 TD
50 34.5 - 345 Bar (500 - 5000 PSI) adjustment and setting.
Standard Setting: i.e. XRDH10350-6T means that both A & B reliefs are screw adjustable
172.4 Bar (2500 PSI) @ .95 LPM (.25 GPM) and have a range of 34.5 - 345 Bar (500 - 5000 PSI). Technical Data
