No. SS2-8113-0320 Azbil Corporation - 8 - Allowable differential pressure Contoured-type metal seat (%CF, LCF, %C, LC) : PTFE packing Valves with type DAP actuator Note) 1) When a backup sysytem for pressure drop at the air source is used, select the allowable differential pressure from whichever is lower-constant supplied air pressure or backup sysytem set pressure (trip pressure). 2) ..: Positioner is necessary. 3) Take care not to cause the maximum allowable differential pressure to exceed the maximum operating pressure designated by ANSI B16. 34-1981 or JIS B2201-1984. 4) The upper figures denote the operating allowable differential pressure. The lower denote allowable differential pressure at full closure.
