6.3 STORAGE
6.3.1 Storage Instructions
If the actuator is not for immediate use, the following precaution must be taken for storage:
• Store the actuator in a clean and dry environment and at a temperature between -20°C (-4°F) and
+40‚C (+104°F).
• It is recommended that the actuator be stored in its original box.
• Do not remove the plastic plugs on air supply ports.
6.3.2 Lifting and Handling
It is recommended to lift the actuators with proper, adequate and permitted systems in relation to the
actuator weight and by following the ruling laws in terms of safety and health protection. The weight of
the actuators is indicated on the Torqturn catalogue and on the related technical data sheets. During the
lifting and the handling of the actuators, it is recommended to avoid clashes and/ or accidental falls in
order to avoid irreparable damages to the actuators and to compromise the functionality.
Contact APV for any information and technical data sheets.
7 . 0 O P E R A T I O N
Typical operation of the actuator involves applying pressure to the appropriate pressure inlet(s) of a
double acting or spring return cylinder by means of a suitable control valve. APV-Torqturn actuators are
sized to ensure the required valve torque is produced at the supply pressure selected by the customer.
All APV-Torqturn actuators feature a fully enclosed body cavity which ensures protection for all moving
parts and eliminates the possibility of injury to operating personnel. APV-Torqturn pneumatic actuators do
not require additional lubricants.
When using APV-Torqturn actuators manually, the supply pressure is required to be vented or equalised
on either side of the power piston (with some provision for handling the minor difference in displacement
of opposing sides of the cylinder position).
a) When operation is a ‘declutchable’ gearbox, move the lever until the mechanism is engaged. With this
done, the gearbox then operates actuator and valve.
7.1 OPERATING FUNCTION AND DIRECTION OF ROTATION
The actuator is a pneumatic device for remote operation 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.
