What type of valve is this?

[jaydebruyne]

NRV and isolation?

 

[PlumbBobBob]

looks like it to me

Looking at the arrow on the side I would say its a check valve (nrv)

 

[jaydebruyne]

I know dome of the iso valves have an arrow too but its the screw above it that makes me think its a verifiable check valve.. Their hot water pressure is quite low and this is on the cold to the combi so gonna change this to see if its the issue

 

[jtsplumbing]

If its been fitted as a service valve you could remove it or replace with full flow valve

Cheers guys

Looks like a gas cock with a test nipple.

Not gas the gas valves like this usually have a pozzi screw and you can see the rubber seal looks like water of an old multipoint

And it would pet-rude further out to put your gauge hose on. It looks like a water connection of a mains multipoint, it's got the screw as a drain.

Maybe is Leo.

my thoughts as well,like the ones that come with the old aristons

 

[jaydebruyne]

So what's the screw for?

So what's the screw for?

test point for measuring gas pressure ,looks like a gas iso has been fitted to water TBH

But there was no way you'd get a gauge hose on there, its not long enough.. ?

Must be a valve of an old multipoint then. The screw is to drain the pipe. If it is it will have a rubber o ring on the screw.

Pooh! Which means I could have misdiagnosed the issue then :/

what was the problem and what did you come to?

Hot water pressure throughout the flat is quite low. Temperature is stable. I thought either there's a blockage somewhere or a valve that is restricting flow and that's the only valve I found.

What a bout the stop tap?

Cold water is fine, its just the hot

As it's not full bore it could be that valve in the pic

I'll soon find out lol

 

[jaydebruyne]

I believe this valve could be a combined isolation and flow regulator.. As seen made by aquaflow:

What you reckon?

 

[Leo21]

Nope, just an isolater with a drain.

Oh.. :/ haha never seen these before
