No. SS2-8113-0310 Azbil Corporation - 8 - Valves with type VP actuator Note) 1) When a backup system for pressure drop at the air source is used, select the allowable differential pressure from whichever is lower constant supplied air pressure or backup system set pressure (trip pressure). 2) 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. 3) The upper figures denote the operating allowable differential pressure. The lower denote allowable differential pressure at full closure.
