WebAug 16, 2010 · Some control valves, like Samson model 3241, strongly recommend that the pipeline upstream and downstream of the control valve should be straight and free of obstructions for a length of at least 6 times the pipe diameter (DN). My questions are: (1) Is this a common rule that people do follow? WebIdeally the control valve response should be linear (from the control system’s perspective). If the PID output changes 5%, the process should respond in a similar fashion regardless of where the output is. (In other words 15% to 20% or 85% to 90% should ideally generate the same process response.) If the valve response is non-linear, control ...
