Sir which types check valve prefered for oxygen and hydrogen gas services for below 2 inch 200 bar pressure

[@sujitprajapati9148]

Perfect video for NRV

[@manishsinha5670]

I need to install nrv for my home. There is 4" pvc pipe coming out of my bathroom into a inspection chamber, which is connected to an outlet pipe of 6" to the road drainage. Road Drains overflow during rain and water enters the bathroom. What type of nrv valve I should opt for. The depth of inspection chamber is only 1" about from the 4" pipe and 0" from 6" pipe. Dimension is 2"*2"*2" for the inspection chamber.

[@mstsshortvideos4004]

Which is best for drain pipes? And how much will a piece cost ?

[@rinkukumar-po8bn]

Very nice video sir

[@shivayogimuppayyanavarmath8646]

Sir is there any place for air valve in nrv

[@rushikeshkasar3965]

Konsa vala best he sir

[@shashankgupta7571]

What is the pressure drop across disc type ch ck valve?

[@vishalkumarjha4542]

Sir any suitable type used for vertical piping? And how does dual plate NRV close itself as it is not against gravity ?

[@gourisankarsamanta7670]

Dual plate NRV is spring loaded. For vertical piping dual plate NRV can be used, if flow is upward.

[@vignesha7049]

Could you share me the comparison of Check Placement in vertical & horizontal.. What is the advantage of placing valve in horizontal

[@sankarghosh1485]

Sir, please make a tutorial video on seals. Different types of seal used, their MOC and their working principle.

[@samirmukherjee4786]

Can we use a NRV in an underground 4" sewer line ? Want to block reverse flow of very heavy rain water.

[@gourisankarsamanta7670]

Yes, NRV can be used inside a pit or chamber so that valve maintenance and gasket replacement will be possible.

[@samirmukherjee4786]

Please suggest a suitable 4" NRV for our house drainage system, our problem is heavy reverse flow of rain water.

[@gourisankarsamanta7670]

@@samirmukherjee4786 please go for swing type or dual plate type flanged NRV.

[@shaibajsayyad3436]

For Compress air which type of NRV is best...?

[@gourisankarsamanta7670]

For compressed air, dual plate NRV is the best.
