Process Plants require that some
of the important process variable such as pressure, flow, level , temperature
etc need to kept and maintained within a required operating range to ensure
that the final product is obtained with the same quality and consistency. For
this reason , there are hundreds or even thousands of control loops all
networked together in the Process plants.
The most important component of the Control loop is the Valve called Control Valve A control Valve is a valve which manipulates a flowing fluid ( process fluids, gas, steam,water etc., to compensate for the fluctuation or variations in the process variable ( due to load disturbances and keeps the regulated process variable as close as possible to the desired Set Point.
