Binary valves in analog control

Continuous control systems are built with standard transducer measured signal, the controller and actuator. The actuator is responsible for the direct setting of the size of the control object. The actuator is connected to the control valve and the actuator position change signal into the flow rate of the working medium. Since the operating element is required the linear characteristics in the standard signal range to work. The other hand, the control valve provides flow characteristics linear or equal percentage. This flow control principle is used in various control systems. The actuator of the control valve is always equipped with a positioner, which corrects errors in the position of the valve relative to the input signal. The presented design of the control valve is an analogue system. Using the technique of converting multiple digital signal causes, the system is susceptible to damage. Remove the intermediate elements can improve the quality control and safety system. Such benefits give a design of the operating element based on direct digital processing unit and control program. The examples of control present article.
