任何一种水力控制阀执行机构都是一种利用能源去驱动阀门的装置。这种水力控制阀装置可能是人力操作的齿轮组，用水力控制阀去开关阀门， 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，水力控制阀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， 水力控制阀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。 水力控制阀对于执行机构最广泛的定义是：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。 水力控制阀执行机构使用液体、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水力控制阀阀门驱动至全开或全关的位置。

Any of the hydraulic control valve actuator is a kind of valve to use energy to drive the device. This hydraulic control valve device may be the human operator's gear, water power control valve to switch the valve, or a complex control and measurement devices with intelligent electronic components, it can be achieved with continuously adjustable valve. With the development of microelectronics technology, the hydraulic control valve actuator becomes more complex. Early implementation of the agency only with the motor position sensing switch gears. Today's executive body has been equipped with more advanced features, hydraulic control valve can not only open or close the valve and the valve can be detected with the implementation of the work of state agencies to provide a variety of predictive maintenance data. Hydraulic control valve for the implementation of the agency's most widely defined as: A to provide linear or rotary movement of the drive, it uses some kind of drive energy and the role of a control signal to work. Hydraulic control valve actuator using liquid, gas, electricity or other energy sources and through motor, cylinder or other devices to drive into the role. Implementing agency for basic hydraulic control valve to drive the valve to fully open or fully closed position.
