    CVHE

    Just pumping out some CVHE's and guess what the charging valve stem has broken off. Any tricks to opening the valve with the chrage still in the machine.

    If you are sitting in a vacuum I would just change it on the fly.

    Ditto Jayguy. Just get yourself a 1/2" ballvalve and nipple, take the handle off the valve make sure its in the closed position and do a quick switch with it in a vacuum . Takin the handle off means you can spin it in quick .

    the reason i like using R718 is because you can still vent it if you put in too much or if you have to make a repair.

    i also like to sniff a special concoction that i make of 78% R728, 21% R732 and about 1% of R740, R744, R720 and some other stuff that i put in there just for fun.

    and after a big meal i will release a little R50

    The lubricant used in R-50 is it vasaline based.
