Great video. But is recommended to install the electromagnetic flowmeter before the control valve, it can prevent empty pipe that produces wrong measuring of the flow.
Thank you! I greatly appreciate the enormous effort you put into creating those animations, which really help with the understanding of the physical phenomena occurring in these systems. Please keep up the good work.
Hey! Thanks a lot for your kind compliment! We are always extremely happy to hear such positive feedback. If you ever have any questions, feel free to reach out to us. Happy learning!
Hello RealPars, You guys have been amazing so far. I'm always anticipating you your video lessons. However, to fully understand the control valve and their service function, I think you should make a video lessons on the ANALOG POSITIONER. Best regards
Hi Obafemi, Thanks for your comment and sharing your feedback with us. We truly appreciate that, and I will make sure to forward your suggestion to our course developers. Thanks again and happy learning!
Can you do another video on advanced print reading? The videos that you did on prints are way too simple and don't show the complexity of most prints in the real world. A lot of people think they can read print but have a hard time finding what they are looking for when they are given a stack of prints or prints with lots of details. Thanks
Thanks for the feedback, Eric! I will surely pass this on to our course developers. Hopefully, this is something we can focus on in future video courses.
Thanks for your comment, and for sharing your topic suggestion! I will happily go ahead and forward this to our course developers. Thanks again, and happy learning!
Thanks for your support, Medo! We're happy to receive such positive feedback. Regarding your question, I am actually not sure about that as our illustrations are created by our Graphic and Animation Department.
Nice graphics, well explained, may need to have a look at the fail closed graphic though. The spring would be above the diaphragm to push it closed in failure.
This video is an amazing start. I wish I could have helped offer a few additional points before it was made. Or saw this when I was learning in the job. there are issues / limitations of each technical choice. My experience is that hydraulic actuators are more robust, respond quicker, more reliable, able to work better on larger valves with a smaller footprint. There can be issues but that is more a maintenance issue. Pneumatic valves also require good maintenance and quality instrument air. They work great for on off valves. They have less control because air within the actuator compresses. If you choose a butterfly valve instead of a globe valve you have less control. The valves have a leakage class and shutoff time requirement. They valves can have lvdt, position sensors or limit switches to communicate if it is behaving properly. Often valves are calibrated with a factory supplied cv curve that is custom to that exact valve. This information needs to be updated to account for variations from the standard values. There opening profiles like pop and glide.
With liquid, there may be no issues but with gas, due to compressibility, this can be an issue due to restrictions. On another note, this may not be to scale, the distance from the valve to the flow meter may be large enough not to bother. Regards.
I really like your amazing videos. Can you make video about the resolver and how does it work. compare to encoder and what is the different between these two kinds of position sensors.
You just picked my brain. I'm actually working on that as we speak. Send me an INMAIL on LinkedIn, Obafemi Jimoh. We could share idea about that. Do you have Aspen Hysys or INtools for sizing and calculation?
@@obafemijimoh918 I use the software provided by the valve manufacturers. A lot of them will run the calculations and then give you a list of models they make that will work with those parameters.
@@Ryarios Are you on LinkedIn? If you are please connect with me. Valve sizing is out of my instrumentation scope but I'd love to know how I can independently size one and and prepare it's calculation and specification.
The main advantage is that a pneumatic control valve has a fail position that the valve returns to when the air signal is lost power loss or failure of the instrument air system. A motorized valve will simply stay in the last position on power loss, which may be in a position that allows fluids or gas to continue to pass. This can be dangerous if that fluid is natural gas or a dangerous chemical. I am not sure which PLC you are referring to. The video is a "digital twin" simulation of a process installation, and the controller shown looks like it could be a Siemens S7-1500 PLC.
Hi @Eshan Patil. Thanks for your question. Most control valves are pneumatic and operate in a full stroke range of 3 to 15 psi or 20 to 100 kPa. But, there is usually a converting device called a Voltage to pressure (E/P) or a Current to pressure (I/P) to convert the signal from the controller into a pneumatic signal to stroke the valve. The valve will begin to move at 1v if an E/P is connected or 4 ma if an I/P is connected. I hope that answers your question.
Please make a video of connection of an rtd that controls the on and off of the heater...thy has to be indications of each process....the whole process should be ran by a plc and pid
Hi thank you for your great clips. Please make a clip about chemical processes and how to control the loop and adjust the loop in chemical processes and petrochemicals. For example, loop adjustment methods and loop control strategies in petrochemicals that produce methanol or ethylene.
Dear RealPars This is another awesome video, I would like to ask if it is possible to make a video on slip ring and how can we change it to a wireless slip ring with keeping the high voltage (400v) with a normal sleep ring and all what concern data and signal with the wireless one if it's possible Thanks in advance!

Hi Alberto, Thanks for your comment! Regarding your question, I am actually not sure about this as our course videos are created by our graphics and animation department.
Yes, the flow rate is the same at the inlet and at the outlet. Unless there is a serious leak around the stem of the valve, a control valve is a flow-through device

I think practically control valves are place after flow meters , first flow is measured then everything comes thereafter...

For liquids it does not matter, but mostly I have seen control valve at upstream of flowmeter (whether it is gas or liquid).
