Description
A double piston, rack and pinion pneumatic actuator incorporating a three point piston support
system, anti-blowout spindle and with high duty synthetic bearings at all bearing points.
This version is a standard aluminum actuator, but incorporating parts and materials suitable for
low temperature operation.
Note
When operating actuators in sub-zero temperatures (< 0°C or < 32°F) care should be taken to
counter the effects of freezing condensate inside the actuator.
Specification
Max. pressure : 120 psi (8 bar)
Torque
: Standard
Media : Air or non corrosive gas
Temperature : -40°F to +176°F (-40°C to +80°C)
Finish
: Polyester non-TGIC based powder coating (see data sheet A4.204.01)
Spare parts
Dedicated low temperature spare parts are available for maintenance or make a standard
actuator suiteable for low temperature operation.
