目前任何一种控制阀执行机构都是一种利用能源去驱动的装置。这种装置可能是人力操作的齿轮组,用它去开关阀门,或者是一种具备复杂控制和测量装置的智能电子部件,用它可实现阀门的连续调节。随着微电子技术的发展,执行机构变得更加复杂。早期的执行机构只不过是带有位置感应开关的马达齿轮传动装置。如今的执行机构已经具备了更多先进的功能,它们不仅可以打开或关闭阀门而且可以检测阀门与执行机构的工作状态为预测性维护提供各种数据。

对于执行机构广泛的定义是:一种能提供直线或旋转运动的驱动装置,它利用某种驱动能源并在某种控制信号作用下工作。
执行机构使用液体、气体、电力或其它能源并通过电机、气缸或其它装置将其转化成驱动作用。基本的执行机构用于把阀门驱动至全开或全关的位置。用与控制阀的执行机构能够精确的使阀门走到任何位置。尽管大部分执行机构都是用于开关阀门,但是如今的执行机构的设计远远超出了简单的开关功能,它们包含了位置感应装置,力矩感应装置,电极保护装置,逻辑控制装置,数字通讯模块及PID控制模块等,而这些装置全部安装在一个紧凑的外壳内。

1、驱动能源,常用的驱动能源是电源或流体源,如果选择电源为驱动能源,对于大尺寸阀门一般选用三相电源,对于小尺寸阀门可选用单相电源。一般电动执行机构可有多种电源类型供选择。有时也可选直流供电,此时可通过安装电池实现电源故障安全操作。
流体源种类很多,首先可以是不同的介质如:压缩空气、氮气、天然气、液压流体等,其次它们可以具备各种压力,第三执行机构具有各种尺寸以提供输出力活力矩。
