Heat on proportioning valve?

hey all, So i have to replace more on my brakes.. The line from the master to the proportioning/metering valve is stuck in the prop valve side... Ive used everything.. vice grips, pipe wrench, PB blaster, I even bought that new sea foam "deep creep" for 12 bucks and it is still stuck... Can I use heat near or on the prop valve... They are basically non existent (year one has them for 90 bucks and i really dont want to spend that). any ideas?

I hope we're talking about the same part, the splitter, pressure differential switch below the master that sends fluid from the master to both front wheels and the rear diff, if so. At the shop we used to cut off the line and use a 6 point socket on the nut, but if you've been in there with vice grips you probably beyond that point. Do not heat the valve, if memory serves me correctly the body is brass, and will transfere heat and burn out the switch seals. Can you remove the valve from the coach and work on it in a vice ?? If you can get it to a vice and blow all the fluid out of the valve , you could try heating the nut with a soldering iron, that's about all the temp the valve will tolerate. Or look closly at the valve and see if the switch is removable, to prevent damage.
Good luck.

If ya hadn't already chewed the nut up, I'd tell ya to put the pipe wrench on and tap on it with a small sledgehammer to break the threads loose after a healthy soaking in WD-40/etc.... Also, double check that yer turning it the right way .
