or utilisation of the actuator or if the actuator installed is not fit for intended purpose. It is the sole
responsibility of the user to ensure the valve type and materials are correctly specified.

• It is important that the actuator is used only within the working limits indicated in the technical
specifications.
• Do not operate the actuator over temperature limits: this could damage internal and external
components (disassembly of spring return actuator may become dangerous).
• Do not operate the actuator over pressure limits: this could damage internal parts as well as cause
damage to the housing and end-caps.
• Do not use the actuator in corrosive environments with incorrect protection: this could damage the
internal and external parts.
• Do not disassemble individual spring cartridges, this may result in personal injury. If maintenance to
springs is necessary, send them to Torqturn.
• Close and disconnect all air supply lines and make sure that air connections are vented during
maintenance and installation on valve.
• Do not disassemble the actuator or remove end caps while the actuator is pressurised.
• Torqturn actuators are designed to be used only on valves.
• Before installing the actuator onto the valve make sure that the rotation direction and the position
indicator are in the correct position.
• If the actuator is incorporated in a system or used within safety devices or circuits, the customer shall
ensure that the national and local safety laws and regulations are observed.

Operating media: -
Dry or lubricated air or inert gases, provided that they are compatible with the actuator’s internal parts
and lubricant. The operating media must have a dew point equal to -20°C (-4°F) or at least 10°C below
the ambient temperature. The maximum particle size contained into the operating media must not exceed
30
µm
.
Supply pressure: -
The maximum supply pressure is 7 or 8 bar as an indication.
For double acting and spring return actuators the working pressure is from 2.5 bar (36 Psi) to 8 bar (116
Psi).
Operating temperature: -
Standard actuators from -40°C (-40°F) to +80°C (+176°F).
