A major advantage of using the Spring Boot Actuator is that it implements a number of production-ready features without requiring the developer to construct their own implementations. [18] If Maven is used as the build tool, then the spring-boot-starter-actuator dependency can be specified in the pom.xml configuration file. [19]
A rotary actuator is an actuator that produces a rotary motion or torque. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically , or use energy stored in springs .
If there is a spring inside of the actuator, it will force the valve open or closed and will keep it in that position while power is restored. An actuator may be specified "fail open" or "fail close" to describe its behavior. In the case of an electric actuator, losing power will keep the valve stationary unless there is a backup power supply.
An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.
When the actuator needs to be moved, an electromagnet counteracts the spring and releases the braking force on the drive nut. Similarly an electromagnetic ratchet mechanism can be used with a linear screw actuator so that the drive system lifting a load will lock in position when power to the actuator is turned off.

Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
