No. SS2-8113-1110 Azbil Corporation - 6 - Allowable differential pressure Metal seat (LV) : PTFE packing Valves with type PSA, HA and VA actuator Note) 1) “.. ” shows a model with standard actuator. 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.
