Aluminum Alloy Rack Pinion Actuator Quarter Turn Pneumatic Actuator
1. Indicatior
A position indicator with Namur mounting is standard on all VESON
pneumatic actuators for mounting accessories.
2.Pinion
the hardened alloy steel pinion is precision ground and Nickel
plated
(over 15um) in order to reduce friction, provide maximum wear
resistance.
Full conformance with the newest standards of ISO5211 & DIN3337.
The dimensions can be customized and as options, stainless steel
and
aluminium alloy are also available.
3.Actutor body.
The aluminum extrusion is hard anodized(over 30um) to protect
against wear and corrosion while reducing piston friction to the
absolute minimum. Other options such as Nickel, Ceramic, PTFE,
Polyester coated are available.
4.End caps
Epoxy coated(over 80um) die cast aluminum end caps provide
maximum resistance against potentially corrosive elements. Other
treatments such as Nickel,Ceramic, PTFE,Polyester coated are
available.
5.Pistons
The precisely-balanced and hard anodized treatment (over 30um)die
cast
aluminum pistons are fitted with high quality rings and guides. The
twin
rack and piston design creates a constant torque output on all
actuators.
6.Travel Ajustment
The standard adjustment is ± 5°in both the open and closed
positions
through easily accessible external adjustment bolts.
7.High performance springs
The high tensile steel springs are coated with Epoxy coated for
corrosion
resistance and longer service. The pre-loaded springs can be safely
&
rapidly disassembled.
8.Bearings&Guides
The highly durable compound material provides high trust stability
with
minimum friction and long life.

► Design & Construction Of AT Series Double Acting Pneumatic
Actuator
1. Full conformance to the latest specification:
ISO5211DIN3337VD/VDE3845and NAMUR.
2. The extruding high-intensity aluminum body possesses a honed
internal surface coated with hone anode oxygenation for long life,
low coefficient of friction and swift performance.
3. Excellent, compact and modernized construction along with
multi-specifications make the selection both economic and
beneficial.
4. All acting surfaces adopt high-quality bearings, resulting in
low friction, high cycle life, and no noise. The two independent
external travel stop adjustment bolts can easily and precisely
adjust ±5°at both open and close directions.
5. The same outline actuator has the functional modes of double
acting and spring return, and the spring return has the normal-open
and normal-close styles.
6. Multi-function position indicator with NUMER is convenient for
mounting accessories.
7. Pre-compressed load spring is convenient for safe mounting and
teardown procedures.
8. Die-casting aluminum pistons and end caps have high intensity
and lightweight.
9. Different O-rings materials are available for high and low
temperature.
10. According to different demands we can offer Multi-travel
rotations (e.g. 120°135°180°) and three position actuators.
11. Solenoid valves are easily mounted without any connecting
plank.
