O V E R V I E W
This instruction manual is for rack & pinion pneumatic actuators. The RP Series rack &
pinion pneumatic actuator has been designed, developed and tested incorporating the
latest technology and materials available, with some innovative design features. As a
result of this product research we have obtained a high grade product with the following
characteristics:
• Reliability
• High performance
• Wider product range permitting a more economical sizing
selection.
• Innovative and patented universal drive shaft and multifunction
position indicator
• Full compliance with latest worldwide specifications
• A wide selection of highest levels of corrosion protection
technology
• Aesthetically compact and modern style with no external cavities
to avoid deposit build up.
