The invention relates to an electric field device () with an ignition protection-type pressure-tight encapsulation for use in explosion-prone regions for controlling and/or regulating a valve unit of a process system, comprising a housing (), in which a control unit () that comprises electronic components and is used as a monitoring, control, and/or regulating unit is arranged, said control unit () having a releasable communication connection to an operating unit (). The housing () can be connected to a drive housing of the valve unit via a mechanical interface (), and the housing has at least one connection feedthrough (), via which at least one line can be connected that is connected to the control unit () via a connection interface (). The invention is characterized in that the housing () is designed as a housing assembly with a modular structure, having a first module () which is formed together with the mechanical interface () to the drive housing and the connection feedthrough (). The control unit () is secured in the first module () and has an interface to a control center, wherein the first module () can be mechanically connected to a cover element () selectively either directly or indirectly in a releasable manner, and the indirect connection of the first module () to the cover element () is produced with the interposition of a second module (). The operating unit () is arranged in a stationary manner in the second module (), and the second module () can be fixed in different angular orientations about a longitudinal axis of the electric field device relative to the first module ().
