RANCO heater control valve testing 120-130

Walter;

I suppose you could plumb it up using 1/2" copper soldered fittings, rubber heater hose and clamps and adapt a cooling system pressure tester to it...

I don't see why a heatgun couldn't be used to check the thermobulb action (careful, it can put out much more heat than should be necessary).

I would be very interested in your impressions and results...please take lots of notes, pix or vids...not long ago, I disassembled a dead RANCO valve generously made available to me by Agent Stangelove...it seemed to me that to straighten the tabs of the frame where the thermobulb valve is housed from the base plate required significant force, and that the tabs would not likely survive another bending to reassemble...I planned to solder them back for reassembly (how did you fare in this operation?...does NAPA still source the seal kit?

I haven't gone further than disassembly with this project, but once rebuilt, intend to publish a detailed article at some point.

Cheers
