Type B: +980pa(+100mmH2O) -295pa(-30mmH2O)
Type C: +1970pa(+200mmH2O) -295pa(-30mmH2O)
Type D: according to user requirement (special pressure rating)
Note:
under normal circumstances, (fire) breathing valve operating pressure to B shall prevail;
Applicable materials:
gasoline, kerosene, diesel, aromatics, sulfur, air and other petrochemical materials;
