Focus on Valves
A next-generation intelligent
valve controller for any valve
Introduced at Valve World Expo and
Conference 2022 (November 29-December
1; Düsseldorf, Germany), the
Neles NDX 2.0 (photo) is a next-generation
intelligent valve controller offering
more sustainable valve-control
performance for all process industries,
valves and applications. With
its modular design, Neles NDX 2.0 is
easy to install, use and service. The
Neles NDX 2.0 has universal performance:
it is designed to work on top
of any valve and actuator, regardless
of the manufacturer or valve size. It
also provides interoperability with the
most common automation systems
and is suitable for all operating environments.
The Neles NDX 2.0 valve
controller provides a sustainable solution
for all process industries, valves
and applications. The Neles NDX 2.0
offers significant savings in air consumption
and, consequently, in energy
efficiency. The pneumatic relay
of the controller has been redesigned
so that it consumes approximately
80 to 90% less air than conventional
controllers, says the company. -

This rotary valve automatically
prevents metal contamination
Developed to protect food, pharmaceutical
and other ingredients from
metal particulate-matter contamination,
the new RotaSafe RS1 valve
rotor (photo) monitors rotary-valve
operation continuously, automatically
detects contact between the
rotor and housing and, in the event
of detection, immediately shuts down
power to the drive motor to stop the
process. The rotary airlock safety system
is triggered before the powders
or other bulk materials can become
contaminated by foreign matter and
before the valve incurs any damage
from metal-to-metal contact. The RotaSafe
RS1 features new programming
and amplification hardware for
enhanced functionality and superior
control over detection accuracy, security
and other parameters. - Gericke

This actuator range now offers
a part-turn option
The CK range of modular electric
valve actuators has been extended
to include a new part-turn variant,
known as the CKQ (photo). The entire
range has a modular design that
provides flexibility and high degrees
of configurability, enabling a fast order
turnaround and quick delivery. CK
actuators provide flow control in nonhazardous
locations and are especially
suited for diverse applications in
the water and power industries. This
new part-turn variant is especially
well suited for harsh and demanding
environments and has an operational
temperature range of -30 to
70°C. The IP68 enclosure protection
is maintained even when the actuator
terminal housing is removed (by using
a double-sealing system around both
parts of the plug and socket connection).

These butterfly valves are
approved for oxygen service
A special version of the R480 Victoria
butterfly valve series (photo) is approved
for use with O2. In the design
for handling O2, all media wetted seal
materials and auxiliary materials (lubricants
and screw locking agents)
from the Victoria butterfly valve series
have been tested and approved by
the German Federal Institute for Materials
Research and Testing (BAM).
The examination for BAM approval
was based on the DIN EN 1797 and
ISO 21010 standard. Approval is limited
to the use of gaseous O2 at a
maximum operating temperature of
60°C and a pressure of 15 bars. -

Reduce TCO, improve safety
with this slab gate valve
This company has introduced an improved
version of its Model M-303
slab gate valve (photo, p. 18). The
advanced-design M-303 offers a
number of features that will help users
in the oil-and-gas sector to simplify
installation and upgrades, improve
