*This valve is designed to be soft soldered into lines without
disassembly, using a low temperature solder to 420°F (216°C).
Higher temperature solders 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.
