HIVAL®Control valves
Process plants consist of hundreds, or even thousands, of control valves all networked together to produce a product to be offered for sell. Each of these control system is designed to keep some important process variable such as pressure, flow, temperature, etc. Within a required operating range to ensure the quality of the end product. Each of these loops receives and internally creates disturbances that detrimentally affect the process variable, and interaction from other loops in the network provides disturbances that influence the process variable.

To reduce the effect of these load disturbances, sensors and transmitters collect information about the process variable and its relationship to some desired set point. A controller then processes this information and decides what must be done to get the process variable back to where it should be after a load disturbance occurs. When all the measuring, comparing, and calculating are done, some type of final control element must implement the strategy selected by the controller.
