*Add Termination No. suffix to base Valve Model No. for complete valve automation package (refer to pages 2&3 for sizing and ordering information).

+Specify Part No. for Pneumatic Actuator assembly only (include Part No. for spring selected from chart on previous page).

**Effective diaphragm area (Ae) decreases linearly with stroke:
20 in.2 (129cm2) -- 2 in.2/in. (.5cm2/mm);
45 in2 (290cm2) -- 3 in2/in (.76cm2/mm);
80 in2 (516cm2) -- 3.5 in2/in (.89cm2/mm).
