Title: S/S 3/8" bsp NRV
Post by: BDCS on May 06, 2013, 08:02:27 pm

Does anyone have a specific valve that they have used and can confirm its durability running 250 bar at 120 degrees. Thanks

Think Lee at blastaway has something like that, maybe a few as I know he was doing a few tests on joining machines together

I'm plumbing the boiler in but need it to be simple ( just like the bloke who works for me ) to change from cold to hot without running through the boiler on cold

Yes thats right but its the nrv that needs to sit in the hot flow that I need to source. I know what I want just need someone who has used a specific v/v

Can you not divert before the boiler  ie engine/pump/unloader/3 way to boiler or cold . Just have two push/quick releases... one hot and one cold. As you set up at the job you could either set up hot or set up cold...or it would only be a case of unplugging the hose and throwing the lever to change between the two.
A non return valve will always be problematic....keep it simple!

So your going to have two balk valves? One to divert the water in the boiler and one to divert into the hose?

Either way you need something to split the water into the hose reel cause the real is either connected to the outlet on the boiler or its connected to cold.

No, just an L valve and a NRV on the outlet of the boiler
