e) Operating drive rotation.
The part turn actuator rotation angle is nominally 90°. ACTUATECH actuator provides a stroke of 92° rotation, from –1° to 91°.
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.
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 20 μm 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 is external protected from
corrosion and wear with 20 μm technical oxidation. The cast aluminium end caps are polyester painted. Driving shaft is in alloy steel
nickel plated and caps screws are in stainless 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.
j) Functional Safety
The ACTUATECH S.p.A. pneumatic actuators are also suitable for installations which require high level of functional reliability, up to
SIL3, in compliance with the IEC 61508 standard.
