MAX-AIR [country] UT Series Flanged Aluminum Actuators

       The UT Series rack & pinion actuators are the original Max-Air innovation featuring a removable flange for easy valve integration, flexible customization, and reliable operation. The UT Series is the Max-Air standard for all 180° rotation units and provides NAMUR standard mounting for accessories, along with our patented ±10° adjustment for both the open and closed positions, all backed by the best unlimited cycle life warranty.

COMPACT DESIGN
The MAX-AIR rack & pinion pneumatic actuator
produces linear torque output in a compact design
utilizing the same body and end caps for double acting
and spring return units.
NAMUR MOUNTING
NAMUR VDI/VDE 3845 and ISO 5211 dimensions
on all sizes. No special blocks are required to mount
solenoid valves, limit switches or positioners.
DEGREE OF TRAVEL
The standard angle of rotation is 90°*. Additional travel
rotations of 120°, 135°, 150° and 180° are available.
For sizes UT16 through UT66, Max-Air features dual
travel stops that provide for ±10° stroke rotation on
both the opening and closing phases—that’s 110° of
travel in a standard 90° actuator!
MULTIPLE OUTPUT SHAFTS
The female pinion drive is standard with a double
square output drive, and optional with a double-D
drive, keyed drive and designs to meet your specific
requirements.
HIGH CYCLE BEARINGS
Shaft bearings isolate the pinion gear from the housing
and support the shaft for high cycle applications. Many
competitive manufacturers do not provide this critical
feature.
RUGGED TOOTH DESIGN
The pinion teeth are engaged the full length and stroke
of the piston. The pinion height allows manual override
without disturbing the indicated positions.
HIGH VISIBILITY POSITION INDICATION
External open/close indicator as standard, available for
all the rotations.
HIGH CYCLE LIFE WEAR PADS
Pistons incorporate double wear pads to separate the
rack from the actuator wall and serve as both guide
and wear bearings.
PRE-LOADED SPRING CARTRIDGES
FOR SAFETY
Epoxy coated special steel springs are pre-loaded with
non-metallic materials. The stainless steel end cap
fasteners are extra long to allow for spring relaxation.
All parts are corrosion resistant.
ALTERNATIVE OPERATING MEDIA
Air pressure operation from 2 to 10 Bar (40–150 PSI).
Water, nitrogen and compatible hydraulic fluids may
also be used to power the actuator.
STAINLESS STEEL FASTENERS
All external fasteners are corrosion resistant stainless
steel.
HONED BORE FOR HIGH CYCLE-LIFE
Extruded aluminum body is internally machined and
lapped to exact specifications. Honing prevents dry
spots from forming within the actuator bore and
therefore eliminates premature seal failure—a critical
aspect to long cycle life. All internal and external
surfaces are hard anodized for corrosion resistance,
with all units permanently lubricated at the factory
with non-silicone grease.
TRACEABILITY
All units are externally stamped with a progressive
traceable serial number.
QUALITY ASSURANCE
100% of all units are factory pressure and leak tested,
and individually boxed for shipment.
BEST WARRANTY IN THE INDUSTRY
Max-Air products are covered by the best warranty
in the industry. Contact your representative for more
