Temperature Effect: For operating temperature from 80°C to 130°C, use the torque multiplier given. For
0°C to 80°C no temperature multiplier is required. For operating temperatures less
then 0°C and above 140°C consult Australian Pipeline Valve.
The above is an approximate guide only, for estimating purposes.
4.5 ACTUATOR INSTALLATION INSTRUCTIONS
The Torqturn 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 the valve i.e. dimensions, output torque, supply pressure, air volume, stroke adjustment,
operating time and operating temperature.
• For safety reasons, the actuator must not be pressurised at any time during
installation as it may result in injury.
• The utmost cleanliness is required during air supply connection 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 operation 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 dangerous and/or corrosive substances in the
working environment enter into the external chambers by using adequate filters
and/or solenoid valves.
• Remove plugs from actuator air connections during installation and operation.
Protect the air connections of actuators not being used immediately.
