AIR TORQUE
• Double Acting operation function (standard rotation) Top View
Air supplied to Port 2 forces the pistons apart and
toward end positions, with exhaust air exiting at Port
4, a counter clockwise rotation is obtained.
• Single Acting operation function (standard rotation) Top View
Air supplied to Port 2 forces the pistons apart and
toward end positions, compressing the springs with
exhaust air existing at Port 4, a counter clockwise
rotation is obtained.
5) ACTUATOR INSTALLATION INSTRUCTIONS
The AT actuator is a pneumatic device for the remote operation of industrial valves. The AT
actuator will operate through 90°, the option is available for 120° or 180° of rotation permitting the
opening and closing of many types of 1/4 turn valves.
All the necessary technical information to install the actuator correctly and safely onto a valve
i.e. Dimensions, Output torque, Air volume, Stroke Adjustment, Operating time, Operating tempe-
rature, Direction of rotation and Weight is stated clearly on the Actuator label, in the catalogue
and technical data sheets. Please read this technical information carefully before proceeding
with the actuator installation.
5.1) Important Safety Notice :
• 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 connect-
ing pipe thread, fittings and seals must be clean and dirt-free.
• When fitting accessories onto the actuator assemble them in such a way that the top of the drive
shaft is easily accessible should manual operation of the actuator be required.
• Before fitting onto the valve make sure that the actuator / valve are correctly orientated,
depending upon which direction of rotation is required.

Maintenance
Air supplied to Port 4 forces the pistons together
with exhaust air exiting at port 2, a clockwise rota-
tion is obtained.
On loss of air pressure (air or electric failure) at
Port 2 allow the springs to force the pistons to the
centre position with exhaust air exiting at Port 2, a
clockwise rotation is obtained.
