Gate Valve or Ball Valve

Thanks. Might work if I plan to turn the valve. I hadn't planned on that but let me check to see if it'll work. Thanks!!!

Yep, but it doesn't say it has to be infinitely adjustable and I still argue that gate valves are for regulating either 0 flow or no flow.

Fluid in a nuke plant is H20. Fluid in the house is H20. The valves look and operate pretty much the same. Especially those on the 2ndary side. The primary ones are still the same, just leak proof. There is no scheduled replacement of valves... unless they wear out.

Nuke plant valves are expected to be in place the life of the nuke plant. They cost too much otherwise. Some are never operated except in emergencies. I have a gate valve on my water supply at home. Not a ball valve.

Not necessarily.

Ball valves are used in nuke plants but usually in the air or hydraulic systems. They aren't as maintainable or leakproof as gate valves.

Make sure the steel rod isn't at a 90 degree angle to the pipe, or you may find that turning the valve on might be a little problematic. ;-)
