d) Operating temperature
Actuator standard working temperature range form –20°C (-4°F) to 80°C (176°F)
For low and high temperature versions please contact ACTUATECH. For high humidity and low temperature application are recom-
mended to use a supplementary protection (e.g. screens, sheds or integral painting).
e) Operating drive rotation
ACTUATECH actuator provides a standard stroke of 100° rotation (-5° +95°), with stroke adjustment of 10°.
Some models are also available with stroke of 90°.
f) Cycle time
The cycle time is dependent on different operating and installation factors such as the supply pressure, the flow capacity, the con-
nection pipe size, the solenoid valve performance, the valve torque and characteristics, environmental temperature condition.

The above time table is referred to a standard actuator working cycle at the following tests conditions:
Ambient temperature: 18°C – 25°C
Motive energy operating medium: compressed air at 5,6 bar
Nominal cycle: 90° in both directions
Load: free
GD actuators operate with solenoid valve 5/2 ISO 1-2. While the GS actuators with solenoid valve 3/2.
Time tested with Electronic Timer device.
NOTE: different working condition such as air pressure, piping connection, filters or solenoid valves, could change the timing of the
operations.
g) Lubrication.
The actuators are factory lubricated for the standard working condition life.
During maintenance and reassembling ACTUATECH recommends using TECNOLUBE SYNTHY POLYMER 402 or equivalents.
h) Internal wear protection
The cylinder is lapped to obtain a surface with fine roughness and is protected with 20μm technical oxidation. The pistons slide sup-
ports are in P.T.F.E. The use of steel bearings on the Scotch-Yoke system ensures no play and low friction during operation.
i) External protection
ACTUATECH standard actuators are suitable for indoor and outdoor installation. The aluminium body and the caps are external pro-
tected form corrosion and wear with 20 μm technical oxidation. Driving shaft and external screws/nuts are in stainless steel.
Some models has driving shaft made in nickel plated carbon steel.
For aggressive atmosphere and severe environmental condition select the required protection from the external finishes showed in
our catalogue or contact directly our technical department.
