Pneumatic Rotary Single Acting Actuator
Offers ISO 5211 Standard Pneumatic Actuator for all your 90° Valves & Dampers Automation Requirements
ACTUATOR ! BECAUSE
- Hard Anodized
Barrel/ Body to Protect from Hazardous atmospher & Corrosion, which enhance life of actuator
- Namur Standard Pinion Top
The pinion (shaft) top drilled and slotted for easy assemling of switch, positioners and other accessories.
- Namur pad for Solenoid Valve
Air Supply ports are covered with interface plate as per NAMUR standard to facilitate direct mounting of solenoid valve at actuator.
- IS0 - 5211 Standard Mounting for valve
Double bottom driling for actuator to valve
assembling & Centering. Designed for strength and easy mounting or interchangeability
- IS0 - 5211 Standard Pinion Bottom
Bottom of the pinion (shaft) as female key, double square hole for assembling on vlaves with square key stem and in line or turned to 45°. Designed for strength and sur-fix with stem
- 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 lifr.
- Compact Design
Actuators are designed as compact and common for both double acting and single acting (spring return) which offers high torque values. Internal sliding surface, lapped and anodized for minimum friction and long life of actuator.

SELECTION OF SINGLE ACTING ACTUATOR
Conclude your required torque value.
Increase 25% for an acceptable safety factor.
Now look on TABLE- D, your required torque value should be nearby higher value of "FIX TORQUE BY SPRING" & TORQUE BY AIR/ GAS PRESSURE".
The found position shows the model of "aira" actuator and working pressure in bar, we need.
EXAMPLE
Suppose we need 120 Nm torque to drive a value.
Increase 25% - 150 Nm for safety factor.
In table given below actuator model ARA- 110-S Show 165 Nm "TORQUE BY AIR/ GAS PRESSURE AT 6 bar"
