Secure, easy selection and more
uptime with one-type-fits-all
valve actuator
There are several factors to consider
whenchoosinganactuator.Manufacturer
Alfa Laval states that easy selection is
crucial in hygienic industries.
To meet these demands, the
company’s Unique DV-ST UltraPure
actuator fits its complete range of
standard diaphragm valves, simplifying
inventory management and making the
specification process quick, easy and
secure.
Regardless of the process or applica-
tion, the same actuator can be stocked
as a spare part for all Alfa Laval Unique
DV-ST UltraPure diaphragm valves,
whether cast, forged or block, and can
even be used for autoclave duties.
The actuator withstands the high
temperatures required for sterilisation,
and operates at working pressures up
to 10 bar (6 bar TFM/EPDM).
Unlike some actuators on the market,
it is able to close the valve at the same
working pressures at 0% pressure drop.
As long as the working pressure remains
below 10 bar (6 bar TFM/EPDM), the
actuator continues to deliver reliable,
trouble-free performance.
There is no need to change the actuator
size or configuration, even if changes in
the process line occur.
Alfa Laval sensing and control units can
easily be integrated with the Unique
DV-ST UltraPure Actuator, which
enables customers to take advantage
of the company’s valve automation
solutions.
Alfa Laval sensing and control units
feature tight tolerance bands to provide
process safety, and no-touch, set-and-
forget sensors with simple set-up.
This minimises human error and
promotes safe and efficient production,
ensuring more uptime.

‘Bulletproof’ solution for tube,
hose and pipe cleaning
New tubes are often dirtier than might
be expected, and can cause contamina-
tion of the product circulating in them as
well as the malfunction of the connected
components.
In regular maintenance, dirty tubes
represent a serious problem in the
industry: they are the cause of system
inefficiency and sudden halts in
production.
Alka provides a tube-cleaning solution
that operates by shooting a special
projectile with compressed air. The
system can be applied to tubes
measuring in internal diameter from
2mm up to a few hundred, and lengths
of 10 to 1,000m (depending on air
capacity), and can also be applied in
the presence of 90° curves, ‘T’ or ‘Y’
couplings or ball valves.
The solution allows cleaning of tubes of
all types, from those used in hydraulic
systems, to air conditioners, and from
the food industry to pharmaceutical.
It can quickly and efficiently degrease,
lubricate and disinfect, using only
minimum quantities of chemical
products, if necessary. The system
can also remove production scraps (eg
from cutting or welding), and can be
used for product recovery in dosage
piping, or as an instrument for regular
maintenance or quality control on new
tubes.
The manufacturer claims that the sys-
tem provides stronger cleaning power
than techniques using compressed air
or flushing.
It can be used on rigid or flexible tubes
and is compatible with a huge number
of different materials.
