I realize this is an older video, but I ask, is there a directional way to install a ball valve? I mean is one side devoted to the input and the other output? On gate valves they have an arrow for direction. But ball valve have nothing. Just wondering...
With a ball valve there is no direction, just make sure its installed the handle can turn freely, and if two or more are installed in parallel, make sure they turn the same way for uniformity an example would be a boiler system. Hopefully that helps
Nibco makes crappy fittings. Zero quality control on Nibco's part. I've gotten fittings that looked like they were bitten off by a shark there were so bad. I'll stick with Viega. Viega is more expensive but much better quality.
And you can also find opinions that the valve should be taken apart to protect the plastic seals, not sure how much heat is put into the valve body and how durable the seal materials are.
my guess is that if its in the open position then the ball is making a tight fit between the nylon and the copper so that the heat will transfer to the nylon that is pressed up tight in there. Maybe if its closed then the ball isn't squeezing the nylon up againsn't the hot valve body.
Very nicely done with one small error. I’ve seen at least a dozen “experts” videos on ball valve soldering. You are the only one that does not allow the valve to cool after doing one side before moving to the other side. If you are at all concerned about protecting the plastic in the valve, that seems like a no brainer thing to do. Also, many recommend a wet rag wrapped around the central part of the valve for the same reason. Otherwise, excellent video. If you wanted a complete tutorial maybe add a brief segment on soldering these valves in the vertical position but hey, there’s lots of other references out there for that anyway.
Hi, why do I need to keep a ball valve in the closed position during soldering? I am going to solder a ball valve. I went to DYI forum and asked if I need to keep the ball valve open or closed? One "expert" replied that the valve must be in the open position to let the hit go away. So, should it be open or closed?
Hey, I would sure like to hear from those manufacturer’s their reasons for having the valve closed. I’ve always done it open… The hand full I have done because I reason… more airflow reduces the potential for internal meltdown. And, yes, one side at a time unless you get paid to do it!
Would you explain to us the change in the valve handle color from red or blue to White as from your factory in Mexico. These are a bother as I must repaint to match the system .
I am no plumber but did this on my main shutoff in 2014 and have never had leaks. I think I did 200 or more solder joints that weekend. My arms were hurting after all that twisting/cutting and preparing the pipe. Copper lasts a lifetime.
Nibco fails in quality control where I have received fittings that are burred and straight up screwed up. And as for your customer service is at it's worst!
Who can tell me the machine supplier for the bending, punching(stretch the internal diameter) and turning for this copper fitting? and T model machine. Many thanks! My email address is zglzhl@gmail.com
