MAX AIR [country] SS Series Actuators

The SS Series actuators take corrosion resistance to the extreme with all of the great engineering features that set us apart from the competition. Our stainless steel actuators conform to the ISO standard which makes valve automation easy and cost effective. Dual patented travel stops allow up to 110° of stroke in a 90° actuator, providing exceptional positioning adjustment.

COMPACT DESIGN
The MAX-AIR stainless steel 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°. For sizes from
SS16 and larger, Max-Air features dual travel stops
that provide for ± 10° stroke rotation on both the
opening and closing phases of the actuator stroke.
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 preloaded
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 40–150 PSI (2 to 10 Bar).
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
The SS Series body is internally machined and honed
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 units are 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.
