Azbil Corporation No. SS2-AGV200-0001 - 19 - Valve seat leakage, Class VI: high shutoff model: soft seat Table 27 Model AGVB nominal size 1/2, 3/4 and 1 inch Note that the allowable differential pressure varies with the rated Cv value you have selected. Air-to-open Note) 1. In the case of using positioners, please the setting of supply pressure with pressure regulator. 2. The maximum allowable differential pressures must not exceed the maximum working pressures specified by JISB2201-1984, ANSIB16.34-1981, and JPI-7S-65-831. Table 28 Model AGVB nominal size 1., 2, 2., 3 and 4 inches Note that the allowable differential pressure varies with the port size (inches) you have selected. Air-to-open Note) 1. In the case of using positioners, please the setting of supply pressure with pressure regulator. 2. The maximum allowable differential pressures must not exceed the maximum working pressures specified by JISB2201-1984, ANSIB16.34-1981, and JPI-7S-65-831.
