I'm currently a first-year mechanical engineering student learning about hydraulic and pneumatic systems. This week's topic is on proportional valves, and I must say, without this video I wouldn't have any idea of the function and operation of the valve. Thank you very much for the video!
ı would like to ask one question.we have two high shov and lov shov this valve firstly read tank pressure and compare the set pressure then make a pressure control based on the threshold.we want to use withput proportional valve or samrt valve is it possible to use with just on and off valve ?
I'm currently working on a project with arduino and proportional control solenoid valve. How do I send pwm signals from an arduino microcontroller to control a 12vdc proportional control solenoid valve?
Thank you very much, what about current consumption at 20% for example? It will drain a lot of current as it stays at steady level the coil of the solenoid valve will work too much isn't it?isn't more convenient to use a servo motor with an MCU to control a standard valve in water applications?
can a simple 24 VDC on-off valve be used to control flow. ? if we apply 12 V to 24 V DC to NC simple ON off SV, what will happen? Will it partially open or will remain closed?
I could clearly understood the concept.. could you tell me the conversion of current to voltage is calculated??... I think mostly the controller sends the output in the range of 0v-5v to the actuator.. am I right?? Please explain? Let me know how do you make these videos 📹 what software ?? It's pretty good 👍
I have a 25 ohms) proportional solenoid valve that uses 200mA-700mA (to operate. I am trying to find a driver or a signal generator for it. Please advise
Good job. Great video series. Can you please explain how do you get 7V on the output from PWM converter at 4:33 in this video ? I understand that 50L/min flow equates to 7.2ma control signal and is representative of 20% duty cycle. But shouldn't this in turn result in 4.8V output from the valve controller (20% of the rated 24V), at least as far as simplified Flow Graph is concerned ?
Yes, that's right. For ease of explanation, I described 7.2mA as 7mA, but to express it in detail, 7.2mA is correct. I don't understand the second question, could you tell me in more detail? :)
Very informative video. Please also tell what if we want to get desired pressure from valve and we have no concern for flow rate, how will this be possible with controller? For changing pressure to desired values, which values from input current and flow rate would change and which would be constant?please tell.
The device in the video is a 'flow control device', and the device you are looking for is probably a 'proportional control regulator'. If you want to automatically control the pressure step by step using electricity, please refer to the product in the link below. www.festo.com/net/SupportPortal/Files/12818/PSI_239_1_en.pdf If you are looking for other manual control regulators, please refer to the products linked below. kcc2018.cafe24.com/en/bbs/search.php?url=http%3A%2F%2Fkcc2018.cafe24.com%2Fen%2Fbbs%2Fsearch.php&stx=KRG
Hello. Can you please help me with Pr 2224 proportional valve controller. What is spring response setting It is showed in the menu as percentage But I can’t figure it out Also I can’t limit the maximum current flowing to the solenoid There is setting for max current I did put my values but it is not controlling the max current Please replay
I have a question please clear my doubt. If i use this proportional solenoid valve from which oxygen gas and LPG fuel gas will flow. At a certain point i want flow of oxygen gas 5-10 LPM and LPG 15-20 LPM then after few seconds I want flow of both gases to be like oxygen 250-350 LPM and LPG 50-80 LPM. Can I do it with this valve? And if i can do with this valve then how I will set my desired flows in different times?
You would just build a parallel set of valves to the initial set that flows at 5-10 and 15-20 your parallel valves would have metering jets to make up the difference at full flow with all valves open at one just activate the first two valves and then the second two on a switch it sounds like you are trying to automate a cutting touch
All the proportional solenoid valves i searched on internet are normally closed...NC type...irrespective of other specifications of a proportional solenoid valve...can any one help me to get the link where i can purchase normally open (NO)type proportional valve.... Alternatively suggest how to convert closed type proportional valve to open type proportional valve.. Thanks in advance :-)

Very informative video,was searching for these kind of videos foe a long time.
Your channel is so great. I like your vidéos. You make pneumatics so easy to understand. Thank you.
I just want to understand, when you are increasing the voltage value does solenoide increase the openning percentage?
The solenoid valve is set according to the voltage value of each coil. It can only be used if the voltage is suitable.
Thank you for this video.
Wow
Thank uou

Goodday, I would like to ask if what was the unit/model of the proportional valve and the PWM controller, thank you.
👍👍👍, please make a video of double acting pneumatic cylinder with locking system(using compressed air)
Thank you for your kind words. I will refer to it when selecting a topic in the future.

Hi this same application can be done using stepper motor??
can a simple 24 VDC on-off valve be used to control flow. ? if we apply 12 V to 24 V DC to NC simple ON off SV, what will happen? Will it partially open or will remain closed?

can you give actual working solenoid with pwm?
@ms.pneumatic Possible to hire you to consult a prototype we are working on?
I have a 25 ohms) proportional solenoid valve that uses 200mA-700mA (to operate. I am trying to find a driver or a signal generator for it. Please advise
It would be better to contact the manufacturer of the proportional solenoid valve and purchase a compatible product.
Good job. Great video series.

@@MsPneumatic The thing is - it’s says 7v, not 7mA!
In the year time this video was posted, you could have caught and fix the mistake.
Voltage is the same. The current changes by lengthening of the “tops” of PWM signal, the longer the tops - the more is current.
Thanks for your vedio. I don't understand completely. Do you have any options to know more ( like books or vedios ) . please let me know
Nice to meet you. Only TH-cam content is still in progress.

Hello. Can you please help me with Pr 2224 proportional valve controller.
What is spring response setting
It is showed in the menu as percentage
But I can’t figure it out
Also I can’t limit the maximum current flowing to the solenoid
There is setting for max current I did put my values but it is not controlling the max current
Please replay
It is probably a word used by the company itself, so I recommend that you inquire with the company where you purchased it.
I have a question please clear my doubt. If i use this proportional solenoid valve from which oxygen gas and LPG fuel gas will flow. At a certain point i want flow of oxygen gas 5-10 LPM and LPG 15-20 LPM then after few seconds I want flow of both gases to be like oxygen 250-350 LPM and LPG 50-80 LPM. Can I do it with this valve? And if i can do with this valve then how I will set my desired flows in different times?
Unfortunately, the product in the video can only be used as a fluid, such as air, inert gas, or water.
You would just build a parallel set of valves to the initial set that flows at 5-10 and 15-20 your parallel valves would have metering jets to make up the difference at full flow with all valves open at one just activate the first two valves and then the second two on a switch it sounds like you are trying to automate a cutting touch

Thanks in advance :-)
what is the name of your PWM control ??
The product name of the controller in the video is 'KPCC-1'. If you have any questions about the product, please contact sales@kccpr.com.
@@MsPneumatic sorry but i don't see that product on the website, can you send me the link
