Features & Benefits
1. Hard Anodized Barrel / Body to Protect from Hazardous atmosphere & corrosion, which enhance life of actuator.
2. Mounting Standard Pinion Top (As Per Namur Standard) The pinion
(shaft) top drilled and slotted for easy assembling of switch, positioners and
other accessories.
3. Adjusting Bolt Adjusting Bolts for 0 – 90° ± 5% Over Travel.
4. ISO – 5211 Standard Mounting for Valve (An International Standard) Double bottom drilling for actuator to valve Assembling & centering. Designed for strength and easy mounting or interchangeability
5. ISO – 5211 Standard Pinion Bottom (An International Standard) Bottom of the pinion (Shaft) as female key, double square-hole for assembling on valves with square key stem and in line or turned to 45O. Designed for strength and sure-fix with stem.
6. Sliding Skates The innovation for replaceable sliding skates, between Pistons (Racks) and internal bore surface of the Actuator, just to avoid metal contact, which enhances the Actuator life.
7. Compact Design “aira” Actuators are designed as compact double acting which offers high torque values. Internal sliding surface, machined and anodized for minimum friction and long life of actuator

3 Position Pneumatic Actuator

Specification & Standard
Body Material
Extruded Aluminium Hard Anodized
Air Pressure
Normal Air Supply Pressure: 4KG/CM², AIR SUPPLY PRESSURE: 8KG/CM² MAX
Rotation
90° – Quarter Turn
Caps And Rack
Aluminium Pressure Die Cast
Features & Benefits
1. Actuator is suitable for coarse – fine adjustment, typically forbatching operations or processes.
2. The Actuator has to be Double Acting.
3. The repeatability is 100% since stopping is by mechanicalstoppers. It is suitable for application calling for the precise fine-coarse adjustment like liquid filling system.
4. The Actuator can be switched to one, position from any otherposition very easily with the solenoid control. The 3rd positionis achieved by the mechanical stopping of the piston movement,in the return stroke by pneumatic stopper pistons.
5. The Intermediate position is present at 20% opening. Theopening can be adjusted as required by the set screw. This is field adjustable.
6. Actuator as a standard, works in reverse action, as opposed toconventional configuration i.e. piston inward stroke opens thevalve, and piston outward stroke closes the valve.
7. The End Stops (+/- 5°) are provided on the closing and openingside of the Actuator for setting valve closing precisely.
8. 5,00,000 Cycles POD.
