InterApp IA250S12.F05-F0714

The rack and pinion pneumatic actuator IA Motion combines innovative design features with the latest technology, materials and protection coatings available, resulting in one of the highest grade pneumatic actuators on the market.

• Compact design with identical body and end caps for double acting and spring return types, allowing field conversion by adding or removing spring cartridges.
• Body made of extruded aluminium with internal and external ALODUR® corrosion protection, with honed cylinder surface for a higher cycle life and lower coefficient of friction.
• Symmetric rack and pinion design for high-cycle life and fast operation. Reverse rotation can be accomplished by inverting the pistons.
• Two independent external travel stop adjustments, enabling an easy and precise adjustment of -5°÷15° / 75°÷95°, in order to get a precise valve positioning.
• One-piece blow-out proof, electroless nickel-plated drive shaft with bearing guided one-piece pinion for improved safety and max. cycle life.
• Fully machined piston teeth for accurate low backlash rack and pinion engagement and maximum efficiency.
• Pistons standard anodised for higher life.
• Multifunction position indicator, adaptable to all kinds of limit and proximity switches.
• Preloaded spring cartridges with coated springs for simple versatile range and corrosion resistance. Spring return actuator can be disassembled without danger on field.
• High quality bearings and seals for low friction, high cycle life and a wide operating temperature range.
• End caps, anodized and Polyester® coated (RAL 5021).
• All used screws in stainless steel for life time corrosion resistance.
• Full compliance to the latest specifications: EN ISO 5211, VDI/VDE 3845, NAMUR and ATEX (Directive 94/9/CE).
• Every single actuator is tested and provided with a unique serial number for traceability.
