Azbil Corporation No. SS2-8113-1200 - 9 - Table 9 Air-to-open Note) 1) Positioner is employed in general. 2) Allowable differential pressure at valve-close in the above table is under the condition of ..P P1 (P2 0). Allowable differential pressure at full closure varies depending on the outlet pressure (P2). Detailed information is avail able on request. 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) Take care not to cause the inlet pressure (P1) to exceed the allowable differential pressure at full closure. 5) The upper figures denote the operating allowable differential pressure. The lower denote the allowable differential pressure at full closure.
