Request schematic for Dacor J Valve

Fri Dec 29, 2017 2:01 pm

Does anyone have a diagram or service manual for an old all-metal Dacor 3/4" J-Valve? Looked in the manuals and catalogs section and only saw regulator info. It doesn't look like rocket science but I'm rebuilding one and want to make sure I'm not leaving out any parts. Thanks. Mark

I have a manual and schematic for a Dacor JV3/4 and J3v Reserve valve. I can scan it and send it if you would like.

That would be awsome, thanks. My email on the VDH link is good. Mark

Ps. Bryan may want it for the manuals section too.

Thanks to time2dive there is now a Dacor J-valve (all metal) schematic in the Manuals & Catalogs Section. Thank you! :D

Well, I got the darn thing apart. Per the schematic all parts are there. Seats look good. Gonna replace the orings and install a new burst disc and it should be good to go. Mark

Quick question. The bonnet nut oring appears to be a -015 but the one in the valve is thicker resulting is a slightly larger OD (but same ID as 015), What am i missing? Does the thicker oring have a different designation. I used an oring size chart but no cigar. In the pic the upper oring is the one currently in the valve. The bottom one is a 015. Thanks for all input. I ain't no engineer. Mark.

UPDATE: Answered my own question. Looks like its a 113. Anyone out there have an extra i could buy off you? Otherwise I'll just order a pack of 'em online. Mark

I ordered a package of 50 #113 O-rings (90 Duro) for $2 so if anyone needs one let me know. Mark.
