NEW ENERPAC
VENTURI VALVES
SLASH RETRACTION
New Enerpac Venturi valves can
improve the reaction speed of single
acting, spring and load-return
cylinders by up to three times,
enhancing workplace efficiency
and saving time when using these
ubiquitous hydraulic tools.
They are available in both manual
and electric models and create
a vacuum-like effect in a pump
system, drawing the oil from
the cylinder back to the pump’s
reservoir at a much faster rate, says
Enerpac’s Darryl Lange
“Venturi valves are an excellent
choice for improving the efficiency
of high tonnage cylinders used
throughout Australia, New
Zealand and Papua New Guinea.
They are also highly compatible
with Enerpac’s new long-stroke
telescopic cylinders used in confined
spaces for efficiency and safety.”
The retraction speed of load
return cylinders can create delay
in completing tasks when their
operation is slower than desired.
This is because, once the load is
removed from a load return cylinder,
the plunger will not fully retract
without additional equipment to
force the plunger back into the base
of the cylinder.
Venturi valves address this issue and
provide a solution for typical users
in industries such as mining and
energy, construction and infrastructure,
manufacturing and materials
handling, as well as electrical, heavy
transport, manufacturing machinery
and motor and turbine maintenance
and heavy lifting across a broad
range of industries.
Retrofit kits are available to upgrade
existing Enerpac pumps, which are
one of the most widely used brands
in Australasia. For field installation
on existing pumps, Enerpac offers
retrofit kits for pumps.
For users who want to take
advantage of Venturi technology, but
whose pump isn’t capable of being
upgraded with a retrofit kit, they can
replace their entire valve with a new
VM33VAC or VE33VAC.
with double or triple input shafts, IEC input flanges
for direct connection of electric motors, output
flanges and a range of suitable torque arms.
The bevel unit in the MaxxDrive range can be
used under very extreme conditions as they can
withstand fluctuating ambient conditions thanks
to a temperature management system. Various
cooling and heating options are available and for
maximum flexibility, the gear units are fitted with
easily accessible back stops for quick and simple
changes to the direction of rotation. Taconite
sealing on the input and output shafts guarantees
a robust shield against dusty or wet environments
and accessible greasing points ensure
maintenance can be undertaken efficiently.
Nord’s development has also extended into
engineered baseplates where mounting of fluid
couplings, disc brakes, auxiliary drives, oil coolers
and other accessories can be connected, tested
and delivered as a full package solution for the
end user.
