Koolance VLV-XUTX4B Drain Valve, Brass

If you were expecting twist-controlled flow, this isn't it. It's basically a four-port manifold and a barb tubing port with a screw-on cover. I use these for both fill and drain ports, then back them up with quarter-turn ball valves. Where leaks are concerned I like backups.Works for me, price is reasonable for the two parts, and you get a spare plug to boot.

It's not so much a drain valve as just a 4-way section. There's no spigot on this; it's a barb on one end and 3 inlets on the other. You can totally use this as part of a drain valve system, but it's not a 'valve' in the mechanical sense. Still, like all Koolance stuff, very rugged, well made; looks pretty and very easy to assemble and use. -1 Star because it's not, as I said, a 'valve'.

using as a silver bullet port pic 1 getting ready to install another silver bullet port pic 2 using only distilled water fir know ?

I have not installed it yet into my system so I can not say as to functionality

Works great as a drain Valve. No mess, no Leaks. No problems. Put it after my Swiftech MCP 35x pumps running in series.

Works well, and don't build a system without one, it is great for the initial air purge and indispensable when draining the system. Just make sure you have a bucket ready when opening (and the system fill plug to avoid vapor lock), as it will release fluid almost on the first twist of the cap.

Well made

really nice just need a male to male fitting
