Azbil Corporation No. SS2-AGV200-0001 - 17 - Valve seat leakage, Class V and Class IV-S1: high shutoff model: metal seat Table 24 Model AGVM 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. 3. In the differential pressure column, upper figures show normal differential pressures and lower figures differential pressures when the valve is fully closed. Table 25 Model AGVM 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-close 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. 3. In the differential pressure column, upper figures show normal differential pressures and lower figures differential pressures when the valve is fully closed.
