– Hazard to the environment due to the leakage of dan-
gerous materials.
The safety information does not take into account:
– Unexpected incidents and events, which may occur
during installation, operation and maintenance.
– Local safety regulations which must be adhered to by
the operator and by any additional installation person-
nel.

3.2 Description
The GEMÜ R481 Victoria soft seated metal butterfly valve has
a metal actuator and is pneumatically operated. Normally
Closed, Normally Open and Double Acting control functions
are available. Various pneumatic actuators are available. The
butterfly valve is available in nominal sizes DN 50 to 300 and
in standard installation lengths ISO 5752/20 | EN 558-1/20 |
API 609 category A (DIN 3202 K1) in wafer and lug body ver-
sions.
3.3 Function
The product controls a flowing medium by being closed or
opened by a control medium.
3.4 Product label
The product label is located on the valve body. Product label
data (example):
Design in accordance with order data
Device-specific data
Year of manufacture
Item number
The month of manufacture is encoded in the traceability num-
ber and can be obtained from GEMÜ. The product was manu-
factured in Germany.
The operating pressure stated on the product label applies to
a media temperature of 20 °C. The product can be used up to
the maximum stated media temperature. You can find the
pressure/temperature correlation in the technical data.
3.5 ATEX label
The product with special function X is intended for use in po-
tentially explosive areas and is equipped with an ATEX label.
On the butterfly valve there is an additional adhesive label
with the ATEX marking for the butterfly valve with bare shaft:
480 50W332A1ELF05 D09 X
II -/2 G 88326775
II -/2 D
Ex h -/IIB T6 …T3 -/Gb X
Ex h -/IIIC T150°C -/Db X
The ATEX marking applies only to the butterfly valve with bare
shaft. The overall evaluation must be carried out by the plant
operator.
4 GEMÜ CONEXO
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.
