Animation product overview
 
DESIGN
 
The 4th GENERATION and POWER TECHNOLOGY (PT) pneumatic rack and
pinion actuators have been designed, developed and tested by AIR TORQUE
incorporating all of the latest technology, materials, and protective coating
available on the market today.
The effect of AIR TORQUE's intense product and market research has resulted
in an extremely high quality actuator having all of the following characteristics:
 
- Reliability
- High performance
- A rational and extensive product range that permits the best sizing
   selection at the lowest cost
- Innovations and patented solutions for a universal drive shaft and a
   multifunction position indicator accepting a wide range of accessories
   selection at the lowest cost
- Full compliance with latest worldwide specifications
- A wide selection of internal and external protective surface
   treatments utilizing recently developed technology specifically designed
   to prevent deterioration due to wear and environmental conditions
- Compact and aesthetically modern style without any external cavities
   where-in avoiding collection points for corrosion to begin

CONSTRUCTION
 
1.Extruded aluminum body with both internal and external corrosion protection having a honed cylinder surface for longer life and a lower coefficient of friction.
 
2.Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life and fast operation. Reverse rotation can be accomplished in the field by simply inverting the pistons.
 
3.Two independent external travel stop adjustments permit easy and precise adjustment of +/- 4° in both directions. This adjustment may be made in either the open or closed position and provides for accurate valve alignment.
 
4.Universal and anti-blowout patented drive shaft for an easy conversion from parallel to diagonal square and vice versa. This feature permits a lower and more flexible stock. UNIVERSAL DOUBLE SQUARE design available as option on 4th Generation and as standard on Power Technology permits easy adaptation to any valve and allows for a lower and more flexible inventory.
 
5.A single compact design utilizing identical body and end caps for both double acting and spring return models. This feature reduces inventory and allows field conversion, by adding or removing modular spring cartridges.
 
6.Multifunctional position indicator for visual position indication and a direct, easy, economical way to mount popular sensors.
 
7.Multiple bearings and guides on pistons and racks for precise operation, low friction, high cycle life and a blowout proof pinion shaft.
 
8.Modular preloaded spring cartridges designed with coated springs for simple range versatility, greater safety and corrosion resistance.
 
9.Fully machined teeth on piston racks and pinion shaft for accurate positioning, low backlash and maximum engagement resulting in overall efficient operation.
 
10.Electroless nickel-plated blowout resistant, bearing guided, one-piece pinion shaft for improved safety and maximum cycle life.
 
11.Selected high quality bearings and seals that provide a wide operating temperature range, low friction and high cycle life.
 
12.Internal and external stainless steel fasteners for long term corrosion resistance.
 
13.Full conformance to following latest specifications: ISO 5211, DIN 3337 and VDI/VDE 3845 for product interchangeability and easy mounting of solenoids, limit switches and other accessories.
