气动执行器是用气压力驱动启闭或调节阀门的执行装置，又被称气动执行机构或气动装置，不过一般通俗的称之为气动头。气动执行器的执行机构和调节机构是统一的整体，其执行机构有薄膜式、活塞式、拨叉式和齿轮齿条式。
气动执行器可以接受连续的气信号，输出直线位移，有的配上摇臂后，可输出角位移。移动速度大，但负载增加时速度会变慢。可靠性高，但气源中断后阀门不能保持（加保位阀后可以保持）不便实现分段控制和程序控制，具有防爆功能。
当压缩空气从A管咀进入气动执行器时，气体推动双活塞向两端(缸盖端)直线运动，活塞上的齿条带动旋转轴上的齿轮逆时针方向转动90度， 阀门即被打开。此时气动执行阀两端的气体随B管咀排出。反之，当压缩空气从B官咀进入气动执行器的两端时，气体推动双塞向中间直线运动，活塞上的齿条带动旋转轴上的齿轮顺时针方向转动90度，阀门即被关闭。此时气动执行器中间的气体随A管咀排出。以上为标准型的传动原理。
根据用户需求，气动执行器可装置成与标准型相反的传动原理，即选准轴顺时针方向转动为开启阀门，逆时针方向转动为关闭阀门。
单作用（弹簧复位型）气动执行器A管咀为进气口，B管咀为排气孔（B管咀应安装消声器）。A管咀进气为开启阀门，断气时靠弹簧力关闭阀门。

Air to Port A forces the pistons outwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port B. Air to Port B forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port A. A口进气，压缩空气推动活塞向外运动，使执行器输出轴逆时针旋转(0o -90 o )，B口排气。 B口进气， 压缩空气推动活塞向内运动，使执行器输出轴顺时针旋转(90o-0o)，A口排气。 |
