6. SYSTEM DESCRIPTION
6.1. Intended Application Area
The positioner Type 024.16.720 is designed to be mounted on pneumatic actuators of process valves for
the control of media.
6.2. Function of the positioner and combination with valve types
Positioner Type 024.16.720 is an electropneumatic position controller for pneumatically actuated control valves
with single-acting actuators.
Together with the pneumatic actuator, the positioner forms a functional unit.
Thecontrolvalvesystemscanbeusedforawiderangeofcontroltasksinuidtechnologyand,dependingon
the application conditions, different process valves from the SED range can be combined with the positioner.
Angle-seatvalves,diaphragmvalvesorballvalvesttedwithacontrolconearesuitable.
“Fig. 1: ” shows an overview of the possible combinations of positioner and different pneumatically actuated
valves. Different actuator sizes and valve nominal widths, not illustrated here, are available for each type. More
precisespecicationscanbefoundontherespectivedatasheets.Theproductrangeisbeingcontinuously
expanded.
