Three Way Valve of HVAC System in Urdu/Hindi
HTML-код
- Опубликовано: 15 апр 2021
- This is HVAC conceptual video about the "Three-way valve of HVAC System" regarding the HVAC system valves which are commonly used in chilled/hot water loops at AHUs and FCUs with accessories. This video is in the Urdu/Hindi language. It is basic learning detailed information for new or fresh engineers or technical field persons. It is also important for HVAC / MEP technical staff to leaning points of view. Here sharing my experience and knowledge that will be helpful to learn & grow for Engineers & Technical staff. If you found anything which is inappropriate then convey it in the comments for my information and rectification in the future.
I have explained the following in this video:
1. What is a three-way valve?
2. Types of three-way valves.
3. Application of the three-way valve.
4. Function of the three-way valve.
5. Operation of the tree-way valve, etc.

Your sound is like Dr Rajiv dixit.
Thank you for your comment! I appreciate the comparison. However, I'm glad that you found my sound similar to his. If you have any questions or if there's anything specific you'd like me to address in future videos, please let me know. Thanks for watching and supporting the channel!

Sir good information thanks. I think apny ministry off since main km kiya hi Islamabad.
Yes, you are right
nice
Thanks
Thanks for video,
Sir why we fitted three way divert valve in return line , not in supply line as like AHUs....
Please explain sir
DRV/2-way/3-way vales is used for control chilled water flow as per design requirements which is installed return pipeline.
It is normally installed on return because of the following reasons:
1. ASHRAE Recommendations.
2. The coil of the unit should be flooded in case the valve is closed.
3. With a control valve on the return side, the water is at a higher pressure through the coil, reducing off gas, thereby lowering dissolved oxygen content. Lower dissolved oxygen extends equipment life by minimizing the air entrapment.
4. In coil return line, after AHU/FCU install two way or three way valve, afterward install DRV due to above reasons.
Tannweer Sir , 3 way mixing valve is placed in return line and 3 way diverting line which is commonly used in HVAC is placed in Supply line ? is this right ?
Mostly in HVAC, 3 way valve install in return line of AHU
Thanks alot sir
Welcome
@@TanweerAhmed Sir kindly guide me how much DRV valve open for per tonnage or for 1 Ton,?
DRV valve finalized as per flow capacity of water. It will open 100% on full load and close as per demand of water.
@@TanweerAhmed dear sir ager ap open close drv par ek video bana den to it's very helpful for us. 🙏🏼

Sir why we install these 2 way ,3 way ,PICV & DRV in return line...???
I have explained in videos. However, 2-way valve is used when chilled water no used or partial used in AHU/FCU then it operate and save energy. 3-way vale is same function but it also divert chilled water. PICV & DRV are used to provide required quantity of water in units as per load requirements.
Actually how to answer simply in interview
The Main Difference between 2 way Valve and 3 way Valve
Both valves actuate through thermostat but 2 way valve resist the flow and 3 way valve divert the flow when temperature achieved. 2 way valve has two ports and three way valve has three ports.
Constant pump chilled water system ,we can place 3-way valve in AHU cooling coil inlet ???
If we place in that system what are the problems can fine
Can you plz explain

Sir return grill bina duct work ke sidha ceiling me lga skta hu...FCU celing mounted hai.to return duct alag se dene ki jarurat h kya ?
Both options are used and this depends on designer because calculation done accordingly
@@TanweerAhmed if area is 650sq ft 800 CFM is required then can i place directly into ceilling.
My answer is same as given already
pls.make a correction red line should be in water return line .supply water should be in blue line.thanks

Fcu actuator valve kaisa check kartey? Kaisa find out kaeage problem koo?
What is a problem?
Boss kya mein line me valve package ke bina btu meter install Kar sakte ha ja ne
Valves are used for maintenance point of view because some you have replaced or repaired then valves are used for on/off purpose. Without valve BTU meters can install but it is not good practice
@@TanweerAhmed thank you boss
Why on earth would we choose to mix flow that's going back to the chiller, instead of mixing what's going into the FCU or AHU?
because requirement of AHU/FCU fulfilled therefore chilled water divert to chiller
Actuvator out mai kyun lagate hai

SIR MERA EK QUESTION H 3WAY VALVE KE LIYE
SIR ISKA SIZE PIPE SIZE SE LARGE HOTA H YA SMALL
AND KITNA DIFFERNECE HOTA H
Valve and pipes sizes remain almost same and some times valve size size small because valve select as per flow.
@@TanweerAhmed SIR HOW CALCULATE THE SIZE
KOI VIDEO YA AAPKE PASS CALCULATION HO PLZ SHARE
Mostly BMS vendor supply these two and three way valves and select valves models according to flow and pressure requirements. Refer catalogue of any valve for this purpose
