1. Top/side mounting standard.
The air supply interface of AOX-P series industrial single acting pneumatic actuator is built according to NUMAR standard. To the interface the NUMAR solenoid valve can be installed directly.
2. Fastener.
All the fasteners of AOX-P series industrial single acting pneumatic actuator are made of stainless steel to be resistant to corrosion for a long time.
3. Bottom mounting standard
The pontes are built in according to latest version of ISO5211,DIN3337(F03-F25) to guarantee the interchangeability and versatility of the products.
4. 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.

Bill of Materials

Performance Data (Single Acting)

Operation Mechanism (Single Acting)

The air source pressure comes into the body of AOX-P series industrial single acting pneumatic actuator between the two pistons from air entrance (2) and pushes the pistons toward the end of the cylinder body while the springs at each ends inside the cylinder body is forced to shrink with the air between the pistons and the ends of the cylinder body released from air entrance (4).in the meantime, the racks of pistons drive the output shaft (gear wheel) simultaneously to rotate anticlockwise. After the direction of the air source pressure is reversed by the solenoid valve, the springs at each end begin to reset and the pistons are forced toward each other by the elasticity with the air between two pistons released from air entrance (2). Meanwhile the output shaft (gear wheel) would be driven by the racks of the pistons simultaneously to rotate clockwise. (if the pistons are assembled in different direction from each other, the output shaft would turn out to rotate in inverse direction when the springs reset, namely the single acting reverse SO type)

Pattern selection of the actuator

The suggested safety factor for AOX-P series industrial single acting 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 oAOX-P series industrial single acting pneumatic actuatorf springs.
