*This valve is designed to be soft soldered into lines without disassembly,
using a low temperature solder to 420°F (216°C). Higher temperature sol-
ders may damage the seat material. Apply heat with the flame directed
AWAY from the center of the valve body. Excessive heat can harm the
seats. After soldering, the packing nut may have to be tightened.
