How Do Vane ActuatorsWork?
Parker vane actuators provide the maximum
amount of output torque from the smallest
possible envelope size. They convert fluid
power pressure into rotary motion for a
wide variety of industrial applications.
Double vane units produce twice the
torque output of single vane actuators
from identical envelope dimensions and
have a maximum rotation of 95°.
A short cylindrical chamber encloses a vane
attached to a central shaft. Fluid pressure
differential is applied through a stationary
barrier (stator) within the cylinder to one
side of the vane. The opposite side of the
vane is connected to exhaust through the
stator. This pressure differential produces
rotation of the vane and central shaft. Due
to vane actuator design there will always
be some internal bypass in these units.
Rotary Actuator Series ACT Features
1.
Heads
-
are precision machined from
aluminum, then hard-coat anodized and
PTFE impregnated to ensure long seal life
and low breakaway pressure.
2.
Body
-
is machined from a one-piece
aluminum extrusion that incorporates the
stator for superior rigidity. The extrusion
is hard-coat anodized and PTFE
impregnated, resulting in a smooth, slick
seal surface which guarantees long seal life
and low breakaway pressure.

3.
Shoulder Seal
-
a nitrile-energized, PTFE seal is used
to reduce bypass flow and friction, providing superior
performance and long life.
4.
Shaft Seal
-
the high-quality, self-lubricated, abrasion-
resistant nitrile seal is a multiple lobe construction for
leakfree operation and greater reliability.
5.
Shaft
-
stainless steel provides high strength and
corrosion resistance for the most demanding
applications.
6.
Bearings
-
hard-coat anodized aluminum-bearing
surface with permanent solid film
lubricant provides substantial
shaft support and wear resistance,
ensuring continuous lubrication,
high performance, and long life.
7.
Mounting
-
combination face and
base mounting offer flexibility in
application and design.
8.
Vane Seal
-
a special self-
lubricated, abrasion-resistant
nitrile compound is molded into a
one-piece vane seal, providing low
breakaway pressure and long life,
even with no lubrication. The vane
seal is also removable so that field
repairs can be made, if necessary.
9.
Vane
-
a hard-coat anodized
aluminum extrusion permanently
affixed to shaft, forming a
structurally sound assembly. The
light weight also reduces inertia
allowing faster operating speeds.
