AT105 Series Air Torque double acting single acting silvery
Aluminum pneumatic rotary actuators
WARNING
1. Do not operate the actuator using inflammable,oxidizing,
corrosive, explosive or unstable gases or liquids (use only not
dangerous fluids - group 2 according to 97/26/EC directive).
Moreover, for actuators installed in potentially explosive zones,
make sure that the internal parts of the actuator do not come into
contact with the external atmosphere.
2. Close and disconnect all air supply lines and make sure that air
connections are vented during maintenance and installation on
valve.
3. Before installing the actuator onto the valve make sure that the
rotation direction and the position indicator are in the correct
position.
4. If the actuator is incorporated in a system or used within
safety devices or circuits, the customer shall ensure that the
national and local safety laws and regulations are observed.
WORKING CONDITIONS AND TECHNICAL DATA
1.Operating media:Dry or lubricated air or inert gases, provided
that they are compatible with the actuator internal parts and
lubricant. The operating media must have a dew point equal to –20°C
(-4°F) or at least 10°C below the ambient temperature. The maximum
particle size contained into the operating media must not exceed 30
µm.
2.Supply pressure:The maximum supply pressure is 8 bar (116 Psi),
only for AT801U it is 7 bar (101,5 Psi).
For double acting and spring return actuators the working pressure
is from 2.5 bar (36 Psi) to 8 bar (116 Psi).
3.Operating time (see technical data sheet):Caution: the operating
time depends on several factors
such as supply pressure, supply system capacity (pipe diameter,
flow capacity of pneumatic accessories), valve type, valve torque
and figures, applied safety factor,cycle frequency, temperature,
etc.
4.Rotation and stroke adjustment (see technical data sheet):
For standard actuators (90° rotation), 120° actuators (120°
rotation), 135° actuators (135° rotation) and 180° actuators (180°
rotation).Stroke adjustment at 0°(closed pistons): +15°max/ - 5°.
Stroke adjustment at 90°, 120°, 135° and 180°(open pistons):
+5°/-15°max. For actuator AT045U the stroke adjustment at 90° (open
pistons) is available only on request.
5.Construction: rack and pinion actuator design suitable for both
indoor or outdoor installations.
6.Protection and corrosion resistance:All the actuators are
supplied with corrosion protection for normal environments. For
corrosion resistance of the different types of protection see
technical data sheet.Before installing the actuator in aggressive
environment, ensure that the selected protection level is suitable.
Quality Standards :
The company for the products are brand new original products, no
second-hand and refurbished products, or leave a compensable ten
and return the full amount , but the buyer due to our purchase of
model error is not responsible for returns, another of the
company's sales of products enjoy one year from the date of
shipment quality assurance , according to the original quality
standards , during warranty with product problems , need
confirmation testing by the manufacturer , the supplier to be
solved , the demand side due to storage , use, poor maintenance
caused by lower-quality product , and not raise objections
