Desperate for Brnz. Seacock Help

[redsky49]

Okay. I did it. I forced a bronze seacock (Wilcox Crittendon) and broke the small handle clean off. I am hauled out and have been servicing the valves.



Seacock is still stuck and I am out of ideas. There is no clearance to tap the nutted end. I have tried PB Blaster, soaking it several times. I have tried to tap the valve body. I have cleared all the calcium buildup (valve is in open position).


My last two thoughts are to place a stopper in the valve outlet and fill with muriatic acid, or to try to find a small butane precision torch and try to heat the valve body enough to break it free.


Don't know how I am going to fix the broken handle, but would appreciate any suggestions to break the valve free. FYI, the seacocks were serviced 4-1/2 years ago. I just haven't exercised the valves enough.
TIA
