GEMÜ releases electrical position indicators and combi switchboxes


Valve manufacturer GEMÜ is expanding its product range for automation components in the processing
industry. The new electrical position indicators GEMÜ 1240, 1241 and 1242 and the combi switchboxes
GEMÜ 4240, 4241 and 4242 will ensure reliable recording of valve end positions and form the basis for
successful process automation – even in potentially explosive areas.

An integrated sensor on the GEMÜ electrical position indicators and combi switchboxes records the end
position of the process valves and transmits it to the plant control system with a signal. With combi
switchboxes, the process valve can also be actuated with the integrated pilot valve.

Optimally adapted

The process valve and automation components are optimally adapted to each other. The entire system is preset and tested, saving
users time and effort for logistics, installation and documentation. The new electrical position indicators and
combi switchboxes can be combined with single-acting or double-acting linear actuators or quarter turn
actuators and are therefore suitable for diaphragm, globe and diaphragm globe valves as well as for ball
valves and butterfly valves. Users can benefit from designs with simple proximity switches or microswitches,
but GEMÜ also offers programmable solutions with 24 V, AS-Interface, DeviceNet and IO-Link interfaces for
modern process automation.

Designs with ATEX, IECex or NEC approvals are available for potentially explosive areas. As a result, users
can achieve reliable monitoring of the installed valves, especially for plants with strict safety or quality
requirements. GEMÜ also supports customers during the automation of their plants in external process
