Air Torque Upgrade Series User Manual

• Actuator designation and marking (see technical data
sheets):
The actuator type, size, operating pressure, output
torque, direction of rotation, spring action, operating
temperature and type of connections/interfaces are
determined by designation.
• All AIR TORQUE actuators are supplied with an identifi-
c
ation label showing the serial number and all necessary
information on use, service, operation and product
designation. Where applicable, the label indicates the
classification according to ATEX Directive 94/9/EC.
4) OPERATING FUNCTION AND DIRECTION OF
ROTATION
The actuator is a pneumatic device for remote opera-
tion of industrial valves. The operation (90°,120°,135° or
180° rotation) may be activated by different methods:
• Direct mounting of solenoid valve (5/2 for double acting,
3/2 for spring return) to pressure connections 2 and 4,
connected to supply and control lines.
• Screwed connection (to pressure connections 2 and 4)
with air lines from separate control cabinet.
The standard rotation (when port 4 is pressurized or
for spring action) is clockwise to close. When port 2 is
pressurized, counter-clockwise rotation is obtained.
Air Torque actuators can be supplied with different types
of assembly/rotation direction depending on the type of
required operation and/or installation, see technical data
sheets.
5) ACTUATOR INSTALLATION INSTRUCTIONS
The Air Torque actuator is a pneumatic device for the remote
operation of industrial valves. The actuator will operate through
90°,120°,135° and 180° rotation permitting the opening and
closing of many types of valves up to 180° rotation.
All the necessary technical information to install the actuator
correctly and safely onto a valve i.e.:
Dimensions, Output torque, Supply pressure, Air volume,
Stroke adjustment, Operating time, Operating temperature,
Direction of rotation and Weight is stated clearly on the
Actuator label, in the catalogue and technical data sheets.
Please read all technical information before proceeding with
the actuator installation.
 5.1) Important safety notice!
• For safety reasons, the actuator must not be pressurized
at any time during installation as injury may result.
• 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.
• 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.
• Before fitting onto the valve, make sure that the actuator/
valve are correctly orientated, depending upon which
direction of rotation is required.
• 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.

DOUBLE ACTING OPERATION FUNCTION
(STANDARD ROTATION TYPE “ST”) TOP VIEW
Air supplied to port 2 forces the pistons towards the actuator end caps.
A counter-clockwise rotation is achieved.
Exhaust air exits from Port 4.
Air supplied to Port 4 forces the pistons inward.
A clockwise rotation is achieved.
Exhaust air exits from Port 2.
SINGLE ACTING OPERATION FUNCTION
(STANDARD ROTATION TYPE “ST”) TOP VIEW
Air supplied to Port “2” forces the pistons toward the actuator end caps,
compressing the springs.
A
counter-clockwise rotation is achieved. Exhaust air exits from Port 4.
T
he loss of air pressure (air or electric failure) at Port “2” allows the springs
t
o force the pistons inward.
A clockwise rotation is achieved.
Exhaust air exits from Port 2.
