5 inch Butterfly Valve on 4 inch Pipe?
5 inch Butterfly Valve on 4 inch Pipe?
(OP)
My boss in his past life remembers using a 5" Butterfly valve on 4" pipe. He has asked me to find the parts to make this happen. Is there a special flange I might use?





RE: 5 inch Butterfly Valve on 4 inch Pipe?
Low pressure water you might find something, but generally a 5" butterfly won't work on a 4" flange as the disc won't turn....
I have seen oddball discs with say 5" bolt holes and then 4" studs welded in the 4" PCD in between, but I don't think you'll find a high pressure / approved version of this.

Also: There's usually a good reason why everyone does it that way
