ULT ULTIMATE SERIES OIL-PULSE TOOLS
(SHUT-OFF TYPE)

Since started the production of
Oil-Pulse Tools about 30 years ago, we have been continuously
developing advanced
mechanisms. Featured with unique Air/Hydraulic mechanism, URYU
Oil-Pulse Tools have now come to the fourth
generation "ULT Ultimate Series" passing through the first
generation "U Single-Blade Series", the second
"UX Two-Blade Series" and the third "ALPHA Double-Chamber
Series". ULT Ultimate Fastening Tools achieve
tremendous light weight & short size in addition to numerous
features and benefits to raise your productivity.


-
Improvement
in Torque Accuracy
Newly adopted Check Valve (PAT.P) stabilizes
the current of oil. By stabilizing the oil
current, the shut-off valve can
sense with accuracy the small volume of
high-pressure oil from the relief valve
section during operation and shuts the
tool off as soon as it has reached the
target torque.
-
Workable at
Low Air Pressure
We have added a Reset Spring (PAT.P) to help
the operation rod return back to the
original position without fail every
time. Therefore, the operation rod can
always sense more accurately the load on the
shut-off valve and shuts the tool
off even when operated at lower air
pressure.
-
Room to
expand
The new Accumulator works as a surge drum
against the sudden rise of oil pressure. And
when the oil temperature
rises during consecutive fastening, the
accumulator will take in the expanded oil
volume and keep the same pulse
condition.
-
High Speed
Fastening
Newly adopted Roller Blades (Driving Blade
with Roller Pin)(PAT.P) reduce the friction
inside the pulse unit and
improve the energy efficiency. They also
create less frictional wear of driving
blades, which will reduce maintenance
costs. Furthermore, they smooth the pulse
blows and shorten the fastening time.
-
Increased
Durability
Our original unique sealing, SU-Ring (PAT.P)
extends the maintenance interval than the
conventional O-Ring.
Compared with our conventional pulse
wrenches, the life cycle becomes increased
by 60% or more with no leakage.
-
Improvement
in Energy Efficiency
For the high-powered dual chamber motor that
minimized torque ripples, we employed 9 pcs.
of specially-coated
blades. The special coating on the blades
creates a better seal in the cylinder,
helping to reduce the weight of the
motor and increasing the energy efficiency.
-
Standard
Handgrip & Body Protector
In addition to the oil pulse mechanism
offering low noise, low vibration and small
reaction, the comfortable handgrip
lightens the burden for operators. Taking
the environmental issue into consideration,
the protective full-cover jacket
is equipped as standard instead of painting.
-
Feather-Touch Throttle Trigger
Feather-touch trigger mechanism (PAT.P) with
interchangeable direction lever lightens the
load imposed on the operator's
finger by at least 50%.
