Azbil Corporation No. SS2-ADV100-0100 - 7 - Allowable differential pressures for model ADVM Note) 1. Note that the maximum allowable differential pressures must not exceed the maximum working pressure specified by JIS B2201-1984, ANSI B 16.34-1981, and JPI-7S-65-83. 2. In the differential pressure column, upper figures show operating differential pressures and lower figures show differential pressures when the valve is fully closed.
