Control valves modulate the flow of fluids in flow, pressure, level, and temperature control systems. They consist of three main parts: a valve body, actuator, and positioner. The positioner, through the actuator, drives the valve in proportion to a control signal. Various types of valve and actuator combinations are available to suit most process control applications. It can be used for a variety of processes including: Pressure Control, Temperature Control, Level Control, Flow Control, and Humidity.
