C-MAX C-5000SR（弹簧2.3.4.5.6可选）单作用执行机构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。气动执行器有时还配备一定的辅助装置。常用的有阀门定位器和手轮机构。阀门定位器的作用是利用反馈原理来改善执行器的性能,使执行器能按控制器的控制信号,实现准确的定位。手轮机构的作用是当控制系统因停电、停气、控制器无输出或执行机构失灵时,利用它可以直接操纵控制阀，以维持生产的正常进行。
Pneumatic actuators are actuators that use pneumatic pressure to drive the opening and closing or regulating valves, also known as pneumatic actuators or pneumatic devices, but commonly referred to as pneumatic heads. Pneumatic actuators are sometimes equipped with certain auxiliary devices. Commonly used are valve positioners and handwheel mechanisms. The function of valve positioner is to use feedback principle to improve the performance of the actuator, enabling the actuator to achieve accurate positioning according to the control signal of the controller. The function of the handwheel mechanism is to use it to directly manipulate the control valve to maintain normal production when the control system experiences power outages, gas shutdowns, controller output failure, or actuator failure.
