Glad to hear check valves are in the running !!!!.....no.matter how you move water to.a boiler, injector, steam pump, axle pump, or hand pump...check valves are always needed....they will certainly make a nice addition to.your line of products !!!!

I second that !!!....a good variety of boiler check valves is a big gap in.the live steam.window right now.....those would be a most welcome addition.!!!

They fed oil to cylinders, and air compressors

How about some nice looking, steam.operated cylinder cocks, and a 3 way valve to operate them.??....that would be a very welcome, nice addition to.your line !!!!!!

I would be interested in nathan or hancock boiler check valves....are you considering adding those along with the top.mounted check valve ?

Is this the new 4-8-4 or the old alco northern ??...I have drawings for the old alco built many years ago

Mcmaster carr has it in 4-40....which is standard coarse thread......is there any reason to be using 4-36 ?????

Wow, thats nice...maybe someday ill get into 3d printing too...lol....but for now I just do.it the old way...outta wood, or just carve the whole thing outta steel...lol

3d printing has become the new norm....its almost put the traditional patternmaker in the poor house..

The easiest solution is to use a follower board, to match the contour of the flange

Pm research has check valves down to 3/16ths mtp......you could make a threaded pipe reducer to take it on down to your 1/8th tubing

Yeah, ive done all that numerous times over the last year....could never get it to.work...I even put a different superscale injector in its place, and it worked great...which verified.all my plumbing.integrity......put the injector in.question back in place....and nothing.......so that was it, swapp...
