AIR TORQUE
• Operating Time:
See Technical Data Sheet.
Caution: The operating speeds depend on several factors such as: supply pressure/supply capac-
ity (i.e. pipe diameter/flow capacity or pneumatic accessory), valve type, valve torque and char-
acteristics, what safety factor is to be applied, frequency of operation and temperature.
• Stroke:
The stroke for AIR TORQUE actuators are as follows (See technical data):
Standard construction: 90° rotation with stroke adjustment at 0° and 90° + or – 4°
Type Y 120
o
Type X 180
• Lubrication:
The actuators are factory lubricated for the life of the actuator in normal working conditions.
The standard lubricant is suitable for use from -20
(HT) temperature service, where special grease is required please contact AIR TORQUE.
Recommended Air Torque actuator lubricants for standard working conditions:
• Construction:
Rack and pinion actuator design suitable for both indoor or outdoor installations.
• Protection and Corrosion resistance:
Ensure actuators are supplied with corrosion protections for normal environments. For severe duties
select the protection required for corrosion protection. See technical data sheet before installing
actuators.
• Actuator designation and Marking:
The actuator type, size, operating pressure, output torque, direction of rotation, orientation of fail-
ure mode, operating temperature and drive type are determined by actuator designation.
AIR TORQUE actuators are supplied with a label showing all of this information: type, model (includ-
ing protection and if applicable the LT or HT for operating temperature), stroke, maximum permis-
sible supply pressure, direction of rotation, output torque, ancillary attachment, pressure connec-
tion, valve actuator attachment and serial number.
4) OPERATING FUNCTION AND DIRECTION OF ROTATION
The actuator is a pneumatic operator for remote actuation of valves. The operation (90° – 120° or
180° rotation) may be connected by different methods:
- Direct mounting of solenoid valves (5/2 for double acting, 3/2 for spring return) to pressure
connections 2 and 4.
- Screwed connection (to pressure connections 2 and 4) with air lines from separate control cabi-
net.
The standard rotation is clockwise to close, counter-clockwise rotation is obtained when port 2 is
pressurised. For actuator marked LF the rotation is counter-clockwise to close, clockwise rotation
is obtained when port 2 is pressurised.
