The interaction of valve components that are equipped with
RFID chips and an associated IT infrastructure actively in-
crease process reliability.
Thanks to serialization, every valve and every relevant valve
component such as the body, actuator or diaphragm, and
even automation components, can be clearly traced and read
using the CONEXO pen RFID reader. The CONEXO app, which
can be installed on mobile devices, not only facilitates and im-
proves the "installation qualification" process, but also makes
the maintenance process much more transparent and easier
to document. The app actively guides the maintenance techni-
cian through the maintenance schedule and directly provides
him with all the information assigned to the valve, such as
test reports, testing documentation and maintenance histor-
ies. The CONEXO portal acts as a central element, helping to
collect, manage and process all data.
