1. Travel Stops.
The two sole adjusting screws at the side surface of the AOX-P series industrial spring return pneumatic actuator which has been already installed on the valve could make the adjustment of location of the valve opening and closing more convenient and accurate. 
2. Indicator for AOX-P series industrial spring return pneumatic actuator.
Multifunctional location indicator, in field visible indicator and standard socket in accordance to VDI/VDE3845、NAMUR could be installed and export all the accessories .
3. Top/side mounting standard.
The air supply interface is built according to NUMAR standard. To the interface the NUMAR solenoid valve can be installed directly.
4. Selected high quality bearings and seals that provide a wide operating temperature range, low friction, and high cycle life.

Performance Data (Single Acting)

Operation Mechanism (Single Acting)

Pattern selection of the actuator

The suggested safety factor for AOX-P series industrial spring return pneumatic actuator under normal working conditions is 30-50%
The torque needed by valve =80N.m
The torque consider safety factor(1+30%)=104N.m
Air supply=5Bar
According to the tale of spring return actuator’s output,
we find output torque of SC00300 is:
Air stroke 0° =172N.m
Air stroke 90° =112N.m
Spring stroke 90°=165N.m
Spring stroke 0°=105N.m
All the output torque is larger than we needed.
During the restoration, the spring return actuators' output torque will not be affected by the inputing air from the Port B.On the contrary ,it will help the restoration of springs.
