Airpower  |  The Result of 30 years experience

Welcome to AirPower Benelux! We are proud to present you twintorque© the new quarter turn actuator, a new concept in the field of actuators. Now is the best time to take advantage of 30 years of experience in the field of actuating technology and peripheral accessories as well as automation & process engineering.
Gains to be made with airpower: Technically mature product know-how, constructed and produced according to international standards, guarantees absolute safety. The most important advantages and benefits in the deployment of twin-torque actuators have been put together and listen on our website. We also assume that it is right that you always have access to our extensive know-how and experience in valve control technology when and where you need it. See also www.airpower-benelux.com

Airpower  |  Pneumatic Actuator Function double acting

When pressure is applied to connection "2", both pistons move apart from their basic position of 0°and move into the 90° switch position. The force from both pistons is transferred onto the pinion "C" via the toothed rack. If the pistons are given pressure through the connection "4", then both pistons move together into the basic position O°.

Basic position 0°

Switch position 90°

End position adjustment

End position adjustment

THe pivoting angle can be adjusted in both end positions with the adjustment screws"B" and "F" in a pressure-free condition by between +5° en -5°. The locknut-nuts "A" ensure that the new position is secured.

Stroke limiting

The rated pivoting angle can be set in the switch position with the setting screws "E" in a pressure-free condition by between + 5 ° eand -30 °.
The lock-nuts "D" ensure that the new postion is secured.

airpower  |  Pneumatic Actuator Function single acting

When pressure is applied to connection "2", both pistons move apart from their basic position of 0° move into the 90° switch position and compress the springs. Release the pressure in the inner chamber through connection "2" the springs push back the pistons into the 0° basic position. The number of springs (4 up to 16 pieces) must be matched to the control pressure beforehand.

Advantages

Construction features
Same dimension for the double and single-acting actuators with 90° pivoting angle. 180° pivoting angle adjustable from 180° to 120°


Position indicator
The position indicator is mounted onto the actuator in such a way that is does not interfere with the namur interface and thereby according to VDI/VDE 3847

End position setting
About two independently functioning adjustment can be seperately adjusted in a range from +5° to -5° on the screw types APD/APS-040-350 the two end positions.


Stroke limiter
In addition to the final position of the twin torque has for types APD/APS -050-210 standard with a stroke limit adjustment in one direction (opening or closing). This means the rated pivoting angle can adjusted in a range of +5° or -30°

Corrosion protection: Housing and Caps
Aluminium housing is hard-anodised and additionally from the outside powder-coated. Caps in die-cast aluminium is likewise powder-coated.

Corrosion protection: Piston
Aluminium die-cast pistons are hard anodised.

Corrosion protection: airpower-safety-springs
Captive springs are plastic-coated.


O-Rings and bearings

Standard seals deployable from -35° to +80° C.

ISO-Flange patterns
Multiple ISO-Flange patterns per acuator size.

Silicon free


Benefits

- Low capital lockup because only dubbel-acting actuators have to be kept in stock and single-acting actuators can be made by         
simply installing the springs. - Simple, safe handling through the use of captive, pre-stressed springs. - Covers a very wide range of applications

- Use of cost-efficient standardised components.
- Quicker, less expensive mounting of signal units.
- Indicators can be seen from long distances.


- Butterfly valves: discs only need to touch the seal and the valve is closed. - Longer service life through low wear. Low torque and low cost choice of actuator. - Ball and plug valves: opened position of the ball, i.e. plug can be adjusted exactly. - Avoids turbulent flow of the medium and cavitations.

- The additional stroke limitation means the amount of flow can be reproducibly set for butterflies and seals.
- Savings in costs, as special solution are simly not needed (e.g.
  special switching cams or electrical solutions)


- Deployment possibilities in almost all situations, especially in
  critical environments.



- Functional security even with using critical control device.


- Good corrosion protection ensures good service life. - From APS-070 non ferrous metal. - Reduced service and maintenance costs.
- No danger of accidents.

- Wide temperature range. - Cost-effective maintenance via easy exchange of sels and wearing parts.

- Costs-savings through flexible automation of valves


- Application also in locations where Silicon is not permitted for
  one reason or another, e.g. in paint spraying shops.
