AB Valves. Just the dimensions that make up the boxy shapes would probably do as I’m pretty sure I’m just going to plumb the pipes right thru the sides w/o worrying about the various fitting faces.



I’m mid-way thru doing a CAD model of a triple valve for a KC brake and I gotta say I wish I hadn’t started.



I think Dennis is right… I gotta go crawl under some old cars.

Has anyone a dimensioned drawing of a triple valve they can share? Any era. All sides. Even a couple of photos of drawings will help.

Dave, are you looking for drawings of triple valves or AB valves? Many model railroaders erroneously say "triple valve" (only used with K brakes, I believe) when they're actually talking about an "AB" valve.
