Jazakaallah bhai... please provide us the details of standard valve package connections in AHU & FCU including btu meter, inlet which valves are used & outlet which valves are used for constant & vfd type flow...
Normally it is installed on the return line because of 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. If it is a hot system, some manufacturers have temperature limitations on the actuators. If there is a180°F limit on the actuator (common to some actuators), the return side is preferred as it will operate at a cooler temperature. 5. If it is a cold system, it is always better to have less thermal breaks on the colder side (e.g.42°F water) than on the warmer return side (e.g.,56°F water). The return side installation reduces sweating on the electronic actuator, which is more prone to failure when wet.

What do you want to say?
@@TanweerAhmed He wants to say that what is the purpose of using 3-way valve in chilled water line ?
Nice explained sir
U are a gem I am preparing watching your video for hvac engineering
Thanks
Ap ki video boht informative thi sir jzak allah
Thanks and Alhamdullah
Jazakallahu khaira. your videos are really helpful to understand deeply.
Welcome
Jazakallah....Thanks for the explanation...you have strong knowledge about the subject
Thanks a lot
Bhut khoob sir
Thanks
Great explanation!
Thanks
good explanation sir
Thanks and welcome
Please post a video of difference between DRV and PICV.Also can we balance FCU with only DRV ?
Watch my other videos of PICV and balancing valve for deep understanding
Very nice sir
مھربانی
Very informative. Jazakallah
Thanks
Good very helpful
الحمدللہ
Thank you so much for your help.
Welcome

Insha'Allah
Good explanation, expecting more and let me known which is the good book to learn
Thanks, these are taken from catalogue of equipment
Sir why we fix drv in return line please answer
Normally it is installed on the return line because of 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.
