AT75 1/4" 1/2" 1" 1.5" final controlling element silvery Aluminum
Pneumatic double acting actuator
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.Before installing the actuator onto the valve make sure that the
rotation direction and the position indicator are in the correct
position.
WORKING CONDITIONS AND TECHNICAL DATA
1.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.
2.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.
3.Construction: rack and pinion actuator design suitable for both
indoor or outdoor installations.
4.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.
Important safety notice!
1.For safety reasons, the actuator must not be pressurized at any
time during installation as injury may result.
2.The utmost cleanliness is required during air supply connection
to the actuator i.e. the connecting pipe
thread, fittings and seals must be clean and dirt-free.
3.When fitting accessories onto the actuators, assemble them in
such a way that the emergency control of the solenoid valve and the
top of the drive shaft are easily accessible, should emergency
manual operations be required.
4.Before fitting onto the valve, make sure that the actuator/ valve
are correctly orientated, depending upon which direction of
rotation is required.
5.For spring return actuators, avoid that dangerous and/or
corrosive substances in the working environment enter into the
external chambers by using adequate filters and/or solenoid valves.
