Rotary Actuator Ball Valves Series ACT
Parker… Leading the Industry
Parker combines many years of vane actuator experience with
innovative product design to lead the industry in the development of
reliable and effcient rotary actuators.When you specify Parker rotary
vane actuators, you can rely on reduced maintenance costs and
increased productivity.
How Do Vane Actuators Work?
Parker vane actuators provide the maximum amount of output torque
from the smallest possible envelope size. They convert fuid 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.
Why Use Parker Vane Style Rotary
Actuator Ball Valves?
• Provides uniform torque in both directions.
• Zero backlash allows precise positioning.
• Simplicity of design.
• Performs under the most adverse ambient conditions.
• No external linkage needed for rotary motion.
• Guaranteed zero external leakage.
• More effcient operation and longer time between servicing.
