AT75 Automotive Automation Control Components Double Acting Pneumatic Valve Actuator

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.
