The control head F783E Ex ‐ ia has been designed for use as actua on of pneuma cally operated process valves and / or for
recording the switching states of these.
The control head F783E Ex ‐ ia is used for actua ng pneuma cally operated hygienic process valves.
For process valve actua on, the control head can be equipped with a single 2/5 solenoid valve.
For the recording and feedback of the process valve switching posi ons to a higher ‐ level control, the control head has been
equipped with two posi on feedback switches. These are NAMUR style 2 ‐ wire induc ve proximity switches.
The F783E Ex ‐ ia control head mounts directly on standard Pentair actuators of fi gure number F257 and F272S. This produces an
integrated, compact and decentralized system of actua on, valve func on and feedback. The following advantages over
centralised solu ons working with valve clusters are achieved:

low installa on expenditure

easy start ‐ up

shorter switching mes and less air consump on due to shorter distances between the pilot valve and the
process valve.
There is a wide range of moun ng op ons available for many other brand actuators in the hygienic food and beverage industry,
as well as common industrial actuators. Please consult a customer services representa ve for more details on moun ng op ons
