1.Energized and self-lubricated strips
Less friction between piston and cylinder
It prevents the bonding of the seal to the cylinder even after long periods of inactivity

2.Slots, bushes and pins made by steel with hardness higher than 50 HRC
Higher resistance to the forces inside the actuator

3.Rolling friction between piston and slot
Less friction

4.Scotch yoke with rolling friction (transforming rotary motion into linear motion using piston and shaft without teeths/gears)
Reduced friction between piston and shaft with consequently less wear on the relevant parts
Empowered Breakaway Torque (BTO & BTC)
Smaller volume/size than rack and pinion actuators (with the same torque) therefore less space required for installation
Less weight than the rack and pinion (-30% kg / Nm), with consequent savings on the construction sizing of the plant/equipment
Lower air consumption compared to the rack and pinion actuators (-40% air cm3/Nm for Double Acting and -20% air cm3/Nm for Spring Return) therefore less load on the compressor or the possibility of using a smaller compressor's size.

5.Rolled cylinder

Less wear of the energized ties thanks to the low roughness of the surface (0.15 micron Ra)

From sizes bigger than DAN15, NAMUR interface for solenoid valve is already integrated.
No need for extra plate.

100% in- house manufacturing process technology
Maximum control and accuracy in all the stages of the manufacturing process

ATEX Certificate
Installation is allowed in a potential explosive environment

SIL 3 Certified
Guarantee of the high level of functional safety.

TECHNICAL FEATURES
Torque from 15 Nm to 480 Nm.
Mounting flange according to ISO 5211; F03 - F05 - F07 - F10
In compliance with EN 15714-3.
Rotation angle: 92° (-1°, +91°)
Torque: directly proportional to the air supply (see table - general catalogue pneumatic actuator DA).
The code numbers after the DA letters, always correspond to the breakaway torque in
Nm by 5,6 bar air supply.
Sizes from DA 60 direct connection with NAMUR solenoid valve.
Sizes DA15 - DA30 can be provided with NAMUR plate on request.
ATEX version in conformity with directive 2014/34/EU. Please add YX at the end of the code for ATEX version.

WORKING CONDITION
Temperature: from -20°C to +80°C.
Air supply: 5,6 bar; maximum 8,4 bar.
Operating media: compressed filtered air, not necessarily lubricated. In case of lubricated air, either non detergent oil or NBR compatible oil, must be used.
