Series 700 actuators are pneumatic
diaphragm operators that have spring return
in both direct and reverse acting styles,
offering fail open and fail closed modes
respectively. The pressed steel diaphragm
case construction along with the nylon
reinforced Buna-N rubber diaphragm permits
a maximum allowable air supply pressure of
80 psig (550 kPag).
This pre-formed diaphragm provides a
constant effective area throughout the full
extent of travel.
With effective diaphragm areas ranging from
60–160 in

(385–1030cm

), Series 700 actua-
tors can provide the necessary stem force to
meet virtually any operating requirement.
