I have started a new project where I have to control the valves operation through Labview 2015,using NI USB cDAQ).
I need to control Flow control valve(open, semi open, partially open, semi close, partially close, fully close) using Labview. It is a globe valve and 4 numbers are used here.
Please let me know, how should l develop the VI for this? How to get started?, any helpful links? If there is any example code?
Its little urgent !

hi Aryans, In order to control valves you need to use DC motors so that by varying the voltage levels you can apply your race conditions here i am attaching a doc this might helpful http://ceia.seecs.nust.edu.pk/pdfs/Valve_Actuator_FYP_Report.pdf Regards, Venugopal

Hi Aryans,
For the requirement you mentioned above, You can just use the Case Structure or "In Range and Coerce" function for realising it.
Any further doubts, please explain it as clearly as possible...

I think it should be fine. But you should be the final person to say whether it meets your requirements.
If you are new to the Labview, i suggest you to just browse through all the available functions and features of the Labview for a day or two. Then, you'll feel much better to work with it.
