3 Intended use
The DFPD quarter turn actuator is intended to actuate process valves, such as ball
valves and butterfly valves with a rotation angle from 0° (valve closed) to 180°
(depending on design).
Note
The operating torque of the actuator must not be higher than the maximum
permissible torque listed in ISO 5211 related to the size of the mounting flange
and coupling.

A shaft is guided outward on both sides through the housing. Through this,
the reaction torque is transmitted to a process valve (è Fig. 1, aB ) and, if applic­
able, a limit switch or position sensor (è Fig. 1, 2 ).
The end stops can be adjusted in the range ± 5° through the end-position adjust­
ment on both sides (è Fig. 1, 9 ).
