Control head
The control head unites the attachments of the control valve and feedback unit with related setting mechanism on the valve actuator in a compact housing.
Wiring is greatly reduced and the installation size of the process valves with the control system is minimized. In addition, there is also a direct spatial assignment of the pneumatic control unit and visual position indicator to the related process valve facilitating error diagnostics.
If necessary, the actuator can be switched locally via the manual override integrated into the control head.
