- This is a practical firefighting System video about the "Zone Control Valve (ZCV) Assembly" in Urdu / Hindi language. It is a practical detailed explanation video for basic learning information about the ZCV Assembly of the fire suppression system. Mostly ZCV assembly is used in a large piping network of firefighting sprinklers systems to control or monitor easily through the zone in case of fire. It is also important for Firefighting or MEP technical staff. Here sharing my experience and knowledge that will be helpful for learning & growing for Engineers & Technical staff who are interested in this topic.
I have explained the following points here:
1. Zone Control Valve Assembly?
2. Supervisory Valve
3. Pressure Reducing Valve (PRV)
4. Flow Switch
5. Test Drain
I am ensured that you can get theoretical as well as practical knowledge of ZCV assembly through the above link & video if you will watch till the end.

Welcome
Assalamualykum sir.
If i set the riser of sprinkler far from the stair. And set the zone controll at the middle side of the building. Is that issue ase per nfpa?
Standpipe system's hose connections, hose cabinets or hose compartments are required in landings of staircase and exit or entry doors therefore mostly riser pipes are installed on the staircase side. You can install a riser pipe in the middle of the building but pipes connection may be difficult/
Bro, I have a light hazard building with 12000m2 area, Can I Provide Fire water supply with Single riser with single Alarm Check valve and multiple Zone control valves?
Or 3 riser with 3 Alarm check valve is must? (Bcs asper nfpa single riser can serve 4000m2 area only)
your second option
Sir I have a godown of Confectionery of 300 square yard. What fire fighting system we should install. Please guide
Wet fire sprinkler system
السلام علیکم
Dear Sir,
Kindly make a video for supervisory switch and fire alarm.
Thanks
Ok noted 😊
Sir os& y valve and supervisory valve me kya difference hai
OS&Y valve with tempering switch will be supervisory valve. Also Supervisory Butterfly valve available. Here both function will be same but physical structure change.
السلام علیکم سر،زبردست ڈیٹیل دے دیا آپ نے شکریہ۔

I will make video about control wiring of ZCV
@@TanweerAhmed thanks sir, we will wait Insha Allah
Sir why we use test drain valve?
Because if sprinkler glass break then when have to replace sprinkler after drain pipelines. Moreover, if you drain valve without sprinkler glass break then ACV activate in pump room and FACP panel inform about zone activation
Bro, I have a single zone wet sprinkler system, Does it required both alarm check valve and zone control valve or alarm Check valve only ?
Single zone means one zone therefore no need ZCV assembly and only required Alarm check valve assembly which will fulfill the NFPA requirements
@@TanweerAhmed Good, Expected answer,
In a combined system (sprinkler &FHC) from where we start fire hose connection, normally FHC line will start just before zcv na?
If no zcv, from where we start fhc line ?
@@habeebrk ZCV is not used in fire hose connection because we use manually fire hose and ZCV is required in auto sprinkler system
@@TanweerAhmed I mean for combined system
@@habeebrk as per your case as it is combine system you can take fhc individual connection from main sprinkler line but with isolation valve after each connection to control fhc.
Why check valve is providing in combined sprinkler riser ZCV Assembly . Please explain.
The requirement for a check valve to be included as part of the connection to the sprinkler system is to permit the standpipe riser to be drained and refilled in a limited amount of time should repair be necessary to any portion of the standpipe riser, fire department hose valves, pipe, and fittings, etc.
The check valve arrangements in
ZCV assembly permit the standpipe system to be drained while allowing the sprinkler pipe to remain water filled. In general, the check valve between the two systems maintains the water volume supplied within the sprinkler piping, thereby limiting the drain and refill time of the overall combination standpipe/sprinkler system. In addition, when combination risers are cross connected (loop or dual feed), the check valves will limit the flow to the appropriate floor where sprinklers have activated and limit circulation of water throughout multiple levels of the building.
Thank you👍🏻👍🏻
Boss Zone Control valve say flow switch ka distance kitna hona chiyay?
2D
High rise building me water pressure top par kitna hoga and overhead tank aur booster pump ke case me pressure distribution kaise kaam karte he please explain.
Kindly watch my firefighting videos and check in my playlist. I hope you will understand
Vaiya please Help me. NFPA As a rule how to calculated fire centrifugal pump water pressure bar and bar to galleon to pound. How to calculation. Please Help me vaiya.
Watch my video i.e. " NFPA-14 Pressure Requirements" which to be helpful for you
Thank you vaiya
It's a Pressure reducing valve. It is required to maintain pressure not more than 175 psi.
Ok
It's a function of prv rather than pdv
Whater curon nozal agar chalu ho jay to floor suich signal dega ae hame pata nahi janna hai
Yes, it will provide signal at fire alarm panel and you have reach at the zone where is happened
Hi sir, Can you please do a video on Vertical turbine fire pump?
Ok noted and thanks
Aoa bro why there isn't nrv in zcva?
And if I use gate valve instead of supervisory valve ?
W.salam, No need NRV in ZCVA because NRV is installed in Pump room. In firefighting standard used supervisory valve because this valve give ON/OFF status on FACP & also physically status, while gate valve does not provide this information.
I worked at Doha metro and we used NRV in zcva
If you are away from pump Room or no access in pump Room then you can use NRV. But NFPA-13 allow NRV with ZCV
AoA sir kya sprinkler 175 psi k pressure pr design nhi hte?
Max design pressure of sprinkler is 150 to 175 psi
But working recommend pressure is 50 to 75 psi
@@TanweerAhmed sir aik jagah zcv me contractor prv nahi laga raha hai kyu pump 8bar ka pressure deraha hai kehta hai zarurat nahi hai prv ki zcv me
If 8 bar = 116 psi pressure of pump then water move up side to floor then gradually pressure decrease in height therefore I also suggest to no need PRV with ZCV (standard recommend working pressure 50 to 75psi but should be under pressure of sprinklers design) if our sprinklers design pressure is 150 to 175psi then no need to install PRV with ZCV
Assalamualaikum wr.please let me know for how much area one zcv will be considered.
As per std 8.2.1 on NFPA 13 it indicates an area of 3720m^2 per control valve, this works out to be 400 sprinklers per control valve
@@TanweerAhmed jazakaallah bhai...
@@TanweerAhmed what will be the main line pipe size if 3720m^2 and 400 sprinkles can be served ,is there any limitations of pipe size .
Kindly watch my video of pipe schedule method regarding pipe size & number of sprinklers. Also another video pipe schedule method for Standpipe
Tanweer Bhai agar kaam shikhna hoto kya Karin

Sir fire fighting system installation drawing Ka upor video Di ja
There is available video in my playlist of firefighting. If you have any questions then you can ask
thanks for videos sir but i need documentation english because my langue arabic english please
I will try subtitles
@@TanweerAhmed thanks sir
From where we take connection for outer fire hydrant in combined sprinkler and fire hydrant system
From discharge header of fire pumps
@@TanweerAhmed thanks to reply
Please confirm me from header or from riser
secondly what will be dia of 4 or 6 inch if our header is 4 inch
Riser means standpipe: this pipe is installed vertically for water flow upward to building, while hydrant are installed outside of building at ground floor (Note: no hydrants are installed inside of building, these are called landing valve or standpipe hose connection with or without cabinet and hose reel)
If header is 4" means your system is not combine system. In hydrant system, minimum main pipe should be 6" diameter as per standard requirements.
@@TanweerAhmed thanks to reply our header is 6 inch and hydrant are out side building
My question is that we will take two connection from header one for riser and one for out side hydrant or only one connection for riser and than from riser we will take a connection for hydrants.
Thanks for your valuable input

Sir 1 ICV m kitne sprinkler install Kiya ja sakta h
What is ICV?
@@TanweerAhmed installation control valve
As per NFPA 13:2019, 4.5.1 The maximum floor area on any one floor to be protected by sprinklers supplied by anyone sprinkler system riser or
combined system riser shall be as follows:
(1) Light hazard - 52,000 ft2 (4830 m2)
(2) Ordinary hazard - 52,000 ft2 (4830 m2). Therefore on any one floor, you can install one Zone Control Valve Assembly and sprinklers quantity to be calculated according to hazard recommended area.
Bhai ZCV ka zikar hi nhi hai kahi 🙄
These all things are part of Zone Control Valve Assembly
