**This valve is designed to be soft soldered into lines without disas-
sembly, using a low temperature solder to 420°F (216°C). Higher tem-
perature 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.
